This enum allows control over how data is treated when internal arrays are returned to the ArrayPool. Be careful to understand what each option does before using anything other than the default of Auto.

Auto has different behavior depending on the host project's target framework. .NET Core 2.1: Reference types and value types that contain reference types are cleared when the internal arrays are returned to the pool. Value types that do not contain reference types are not cleared when returned to the pool. .NET Standard 2.0: All user types are cleared before returning to the pool, in case they contain reference types. For .NET Standard, Auto and Always have the same behavior.

The Always setting has the effect of always clearing user types before returning to the pool. This is the default behavior on .NET Standard.You might want to turn this on in a .NET Core project if you were concerned about sensitive data stored in value types leaking to other pars of your application.

Never will cause pooled collections to never clear user types before returning them to the pool. You might want to use this setting in a .NET Standard project when you know that a particular collection stores only value types and you want the performance benefit of not taking time to reset array items to their default value. Be careful with this setting: if used for a collection that contains reference types, or value types that contain reference types, this setting could cause memory issues by making the garbage collector unable to clean up instances that are still being referenced by arrays sitting in the ArrayPool.

Represents a read-only collection of pooled elements that can be accessed by index

The type of elements in the read-only pooled list.

Gets a for the items currently in the collection.

Implements a variable-size list that uses a pooled array to store the elements. A PooledList has a capacity, which is the allocated length of the internal array. As elements are added to a PooledList, the capacity of the PooledList is automatically increased as required by reallocating the internal array.

This class is based on the code for but it supports and uses when allocating internal arrays.

Constructs a PooledList. The list is initially empty and has a capacity of zero. Upon adding the first element to the list the capacity is increased to DefaultCapacity, and then increased in multiples of two as required.

Constructs a List with a given initial capacity. The list is initially empty, but will have room for the given number of elements before any reallocations are required.

Constructs a PooledList, copying the contents of the given collection. The size and capacity of the new list will both be equal to the size of the given collection.

Gets a for the items currently in the collection.

Gets and sets the capacity of this list. The capacity is the size of the internal array used to hold items. When set, the internal Memory of the list is reallocated to the given capacity. Note that the return value for this property may be larger than the property was set to.

Read-only property describing how many elements are in the List.

Returns the ClearMode behavior for the collection, denoting whether values are cleared from internal arrays before returning them to the pool.

Gets or sets the element at the given index.

Adds the given object to the end of this list. The size of the list is increased by one. If required, the capacity of the list is doubled before adding the new element.

Adds the elements of the given collection to the end of this list. If required, the capacity of the list is increased to twice the previous capacity or the new size, whichever is larger.

Adds the elements of the given array to the end of this list. If required, the capacity of the list is increased to twice the previous capacity or the new size, whichever is larger.

Adds the elements of the given to the end of this list. If required, the capacity of the list is increased to twice the previous capacity or the new size, whichever is larger.

Advances the by the number of items specified, increasing the capacity if required, then returns a Span representing the set of items to be added, allowing direct writes to that section of the collection.

The number of items to add.

Gets a view over the data in a list. Items should not be added or removed from the list while the returned span is in use.

Searches a section of the list for a given element using a binary search algorithm.

Elements of the list are compared to the search value using the given IComparer interface. If comparer is null, elements of the list are compared to the search value using the IComparable interface, which in that case must be implemented by all elements of the list and the given search value. This method assumes that the given section of the list is already sorted; if this is not the case, the result will be incorrect. The method returns the index of the given value in the list. If the list does not contain the given value, the method returns a negative integer. The bitwise complement operator (~) can be applied to a negative result to produce the index of the first element (if any) that is larger than the given search value. This is also the index at which the search value should be inserted into the list in order for the list to remain sorted.

Searches the list for a given element using a binary search algorithm. If the item implements then that is used for comparison, otherwise is used.

Clears the contents of the PooledList.

Contains returns true if the specified element is in the List. It does a linear, O(n) search. Equality is determined by calling EqualityComparer{T}.Default.Equals.

Copies this list to the given span.

Ensures that the capacity of this list is at least the given minimum value. If the current capacity of the list is less than min, the capacity is increased to twice the current capacity or to min, whichever is larger.

Returns an enumerator for this list with the given permission for removal of elements. If modifications made to the list while an enumeration is in progress, the MoveNext and GetObject methods of the enumerator will throw an exception.

Equivalent to PooledList.Span.Slice(index, count).

Returns the index of the first occurrence of a given value in this list. The list is searched forwards from beginning to end.

Returns the index of the first occurrence of a given value in a range of this list. The list is searched forwards, starting at index index and ending at count number of elements.

Returns the index of the first occurrence of a given value in a range of this list. The list is searched forwards, starting at index index and upto count number of elements.

Inserts an element into this list at a given index. The size of the list is increased by one. If required, the capacity of the list is doubled before inserting the new element.

Inserts the elements of the given collection at a given index. If required, the capacity of the list is increased to twice the previous capacity or the new size, whichever is larger. Ranges may be added to the end of the list by setting index to the List's size.

Returns the index of the last occurrence of a given value in a range of this list. The list is searched backwards, starting at the end and ending at the first element in the list.

Returns the index of the last occurrence of a given value in a range of this list. The list is searched backwards, starting at index index and ending at the first element in the list.

Returns the index of the last occurrence of a given value in a range of this list. The list is searched backwards, starting at index index and upto count elements

This method removes all items which match the predicate. The complexity is O(n).

Removes the element at the given index. The size of the list is decreased by one.

Removes a range of elements from this list.

Reverses the elements in this list.

Reverses the elements in a range of this list. Following a call to this method, an element in the range given by index and count which was previously located at index i will now be located at index + (index + count - i - 1).

Sorts the elements in this list. Uses the default comparer and Array.Sort.

Sorts the elements in this list. Uses Array.Sort with the provided comparer.

Sorts the elements in a section of this list. The sort compares the elements to each other using the given IComparer interface. If comparer is null, the elements are compared to each other using the IComparable interface, which in that case must be implemented by all elements of the list. This method uses the Array.Sort method to sort the elements.

ToArray returns an array containing the contents of the List. This requires copying the List, which is an O(n) operation.

Sets the capacity of this list to the size of the list. This method can be used to minimize a list's memory overhead once it is known that no new elements will be added to the list. To completely clear a list and release all memory referenced by the list, execute the following statements:


            list.Clear();
            list.TrimExcess();

For example, left aligned text is wrapped such that the leftmost glyph alignment point on each line falls exactly on the left edge of the rectangle. Note that for many fonts, especially in italic style, some glyph strokes may extend beyond the edges of the alignment rectangle. For this reason, it is recommended that clients draw text with at least 1/6 em (i.e of the font size) unused margin space either side. Zero value of MaxTextWidth is equivalent to the maximum possible paragraph width.

This class represents an elliptical arc on a 2D plane. This class is adapted for use with WPF StreamGeometryContext, and needs to be created explicitly for each particular arc. Some helpers It can handle ellipses which are not aligned with the x and y reference axes of the plane, as well as their parts. Another improvement is that this class can handle degenerated cases like for example very flat ellipses(semi-minor axis much smaller than semi-major axis) and drawing of very small parts of such ellipses at very high magnification scales.This imply monitoring the drawing approximation error for extremely small values.Such cases occur for example while drawing orbits of comets near the perihelion. When the arc does not cover the complete ellipse, the lines joining the center of the ellipse to the endpoints can optionally be included or not in the outline, hence allowing to use it for pie-charts rendering. If these lines are not included, the curve is not naturally closed.
