Subtracts an offset from the value of a pointer.
Assembly: mscorlib (in mscorlib.dll)
The method does not throw an exception if the result is too small to represent as a pointer on the specified platform. Instead, the subtraction operation is performed in an unchecked context.
Languages that do not support operator overloading or custom operators can use this method to subtract an offset from the value of a pointer.
The following example instantiates an IntPtr object that points to the end of a ten-element array, and then calls the method to iterate the elements in the array in reverse order.
