Parameters

ptr

The base address in unmanaged memory of the target object.

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.
