Writes a 16-bit signed integer value to unmanaged memory at a specified offset.
Assembly: mscorlib (in mscorlib.dll)
public: [SecurityCriticalAttribute] static void WriteInt16( IntPtr ptr, int ofs, wchar_t val )
Parameters
- ptr
-
Type:
System::IntPtr
The base address in the native heap to write to.
- ofs
-
Type:
System::Int32
An additional byte offset, which is added to the ptr parameter before writing.

-
Type:
System::Char

WriteInt16 enables direct interaction with an unmanaged 16-bit signed array, eliminating the expense of copying an entire unmanaged array (using Marshal::Copy) to a separate managed array before setting its element values.
Writing to unaligned memory locations is supported.
The following example demonstrates how to read and write to an unmanaged array using the ReadInt16 and WriteInt16 methods.
requires full trust for the immediate caller. This member cannot be used by partially trusted or transparent code.
