A read-only field that represents a pointer or handle that has been initialized to zero.
Assembly: mscorlib (in mscorlib.dll)
The value of this field is not equivalent to nullptr. Use this field to efficiently determine whether an instance of UIntPtr has been set to a value other than zero.
For example, assume the variable, uip, is an instance of UIntPtr. You can determine if it has been set by comparing it to the value returned by a constructor, for example: " if uip != new UIntPtr(0)... ". However, invoking a constructor to get an unintialized pointer is inefficient. It is better to code either " if uip != UIntPtr.Zero... ", or " if !UIntPtr.Zero.Equals(uip)... ".
