Marshal.UnsafeAddrOfPinnedArrayElement Method

.NET Framework 4

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

Namespace:  System.Runtime.InteropServices
Assembly:  mscorlib (in mscorlib.dll)
C#
C++
F#
VB
Copy 
public static IntPtr UnsafeAddrOfPinnedArrayElement(
	Array arr,
	int index
)

Parameters

arr
Type: System.Array
The array that contains the desired element.
index
Type: System.Int32
The index in the arr parameter of the desired element.

Return Value

Type: System.IntPtr
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 not validate the array passed to it; this can result in unexpected behavior.
