Assembly: mscorlib (in mscorlib.dll)
static member Copy : source:IntPtr * destination:int16[] * startIndex:int * length:int -> unit
Parameters
- source
- Type: System.IntPtr
The memory pointer to copy from.
- destination
- Type: System.Int16[]
The array to copy to.
- startIndex
- Type: System.Int32
The zero-based index in the destination array where copying should start.
- length
- Type: System.Int32
The number of array elements to copy.
| Exception | Condition |
|---|---|
| ArgumentNullException | source, destination, startIndex, or length is a null reference (Nothing in Visual Basic). |
Unmanaged, C-style arrays do not contain bounds information, which prevents the startIndex and length parameters from being validated. Thus, the unmanaged data corresponding to the source parameter populates the managed array regardless of its usefulness. You must initialize the managed array with the appropriate size before calling this method.
