System.Runtime.InteropServices.Marshal.WriteByte Method

Writes a single byte value to unmanaged memory at a specified offset.

Syntax

public static void WriteByte (IntPtr ptr, int ofs, byte val)

Parameters

ptr
The base address in unmanaged memory to write to.
ofs
An additional byte offset, which is added to the ptr parameter before writing.
val
The value to write.

Remarks

Marshal.WriteByte(IntPtr, int, byte) enables direct interaction with an unmanaged C-style byte array, eliminating the expense of copying an entire unmanaged array (using Marshal.Copy(Int32[], int, IntPtr, int)) to a separate managed array before setting its element values.

Requirements

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