Allocates an array while skipping zero-initialization, if possible.
public static T[] AllocateUninitializedArray<T> (int length, bool pinned = false);
static member AllocateUninitializedArray : int * bool -> 'T[]
Public Shared Function AllocateUninitializedArray(Of T) (length As Integer, Optional pinned As Boolean = false) As T()
Type Parameters
- T
Specifies the type of the array element.
Parameters
- length
- Int32
Specifies the length of the array.
- pinned
- Boolean
Specifies whether the allocated array must be pinned.
Returns
An array object with uninitialized memory.
Remarks
If pinned is set to true
, T
must not be a reference type or a type that contains object references.
Skipping zero-initialization is a security risk. The uninitialized array can contain invalid valuetype instances or sensitive information created by other parts of the application. The code operating on uninitialized arrays should be heavily scrutinized to ensure that the uninitialized data is never read.
Skipping zero-initialization using this API only has a material performance benefit for large arrays, such as buffers of several kilobytes or more.
