Public Shared Function UnsafeAddrOfPinnedArrayElement (arr As Array, index As Integer) As IntPtr

Parameters

arr
Array

The array that contains the desired element.

index
Int32

The index in the arr parameter of the desired element.

Returns

IntPtr

nativeint

The address of index inside arr.

Attributes
ObsoleteAttribute SecurityCriticalAttribute

Remarks

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.
