Exception | Condition |
---|---|
ArgumentNullException | target is nulla null reference (Nothing in Visual Basic). -or- method is nulla null reference (Nothing in Visual Basic). |

Remarks
This constructor cannot be used in application code. To create a delegate by specifying the name of an instance method, use an overload of the CreateDelegate method that specifies a method name and a target object. For example, the CreateDelegate method overload creates a delegate for an instance method with a specified name.
This constructor creates delegates for instance methods only. An instance method is a method that is associated with an instance of a class; a static method is a method that is associated with the class itself.
