A read-only field that represents a pointer or handle that has been initialized to zero.
Public Shared ReadOnly Zero As IntPtr
Dim value As IntPtr value = IntPtr.Zero
public static readonly IntPtr Zero
public: static initonly IntPtr Zero
public static final var Zero : IntPtr
The value of this field is not equivalent to nullNothingnullptra null reference (Nothing in Visual Basic). Use this field to efficiently determine whether an instance of IntPtr has been set to a value other than zero.
For example, assume the variable, ip, is an instance of IntPtr. You can determine if it has been set by comparing it to the value returned by a constructor, for example: " if ip != new IntPtr(0)... ". However, invoking a constructor to get an unintialized pointer is inefficient. It is better to code either " if ip != IntPtr.Zero... ", or " if !IntPtr.Zero.Equals(ip)... ".
