This API is not CLS-compliant.
Copies bytes from the source address to the destination address.
public:
static void CopyBlock(System::Byte % destination, System::Byte % source, System::UInt32 byteCount);
public static void CopyBlock (ref byte destination, ref byte source, uint byteCount);
[System.CLSCompliant(false)]
public static void CopyBlock (ref byte destination, ref byte source, uint byteCount);
static member CopyBlock : byte * byte * uint32 -> unit
[<System.CLSCompliant(false)>]
static member CopyBlock : byte * byte * uint32 -> unit
Public Shared Sub CopyBlock (ByRef destination As Byte, ByRef source As Byte, byteCount As UInteger)
Parameters
- destination
- Byte
The managed pointer corresponding to the destination address to copy to.
- source
- Byte
The managed pointer corresponding to the source address to copy from.
- byteCount
- UInt32
The number of bytes to copy.
- Attributes
Remarks
This API corresponds to the cpblk
opcode. Both the destination
and source
pointers are assumed to be pointer-aligned. See ECMA-335, Sec. III.3.30 ("cpblk - copy data from memory to memory") for more information.
Caution
This API is not intended for copying arbitrary-length runs of memory. Consider instead using MemoryCopy or CopyTo for this scenario.
