volatile keyword

The volatile keyword can be applied to fields of these types:

Reference types.

Pointer types (in an unsafe context). Note that although the pointer itself can be volatile, the object that it points to cannot. In other words, you cannot declare a "pointer to volatile."
Simple types such as sbyte, byte, short, ushort, int, uint, char, float, and bool.
An enum type with one of the following base types: byte, sbyte, short, ushort, int, or uint.
Generic type parameters known to be reference types.
IntPtr and UIntPtr.
