Copy Method (Int16[], Int32, IntPtr, Int32)

Marshal::Copy Method (array<Int16>, Int32, IntPtr, Int32)

Copies data from a one-dimensional, managed 16-bit signed integer array to an unmanaged memory pointer.

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

static void Copy(
	array<short>^ source, 
	int startIndex, 
	IntPtr destination, 
	int length


Type: array<System::Int16>
The one-dimensional array to copy from.
Type: System::Int32
The zero-based index in the source array where copying should start.
Type: System::IntPtr
The memory pointer to copy to.
Type: System::Int32
The number of array elements to copy.


startIndex and length are not valid.


source, startIndex, destination, or length is nullptr.

You can use this method to copy a subset of a one-dimensional managed array to an unmanaged C-style array.

The following example copies an array to unmanaged memory and then copies the unmanaged array back to managed memory.
