Marshal.UnsafeAddrOfPinnedArrayElement Method

Gets the address of the element at the specified index inside the specified array.

Namespace: System.Runtime.InteropServices
Assembly: mscorlib (in mscorlib.dll)

public static IntPtr UnsafeAddrOfPinnedArrayElement (
	Array arr,
	int index
)
public static IntPtr UnsafeAddrOfPinnedArrayElement (
	Array arr, 
	int index
)
public static function UnsafeAddrOfPinnedArrayElement (
	arr : Array, 
	index : int
) : IntPtr

Parameters

arr

The Array containing the desired element.

index

The index in the arr parameter of the desired element.

Return Value

The address of index inside arr.

The array must be pinned using a GCHandle before it is passed to this method. For maximum performance, this method does no validation on the array passed to it; this can result in unexpected behavior.

NoteNote

This method uses SecurityAction.LinkDemand to prevent it from being called from untrusted code; only the immediate caller is required to have SecurityPermissionAttribute.UnmanagedCode permission. If your code can be called from partially trusted code, do not pass user input to Marshal class methods without validation. For important limitations on using the LinkDemand member, see Demand vs. LinkDemand.
