Exceptions
| Exception | Condition |
|---|---|
| ArgumentNullException | type is nulla null reference (Nothing in Visual Basic). -or- target is nulla null reference (Nothing in Visual Basic). -or- method is nulla null reference (Nothing in Visual Basic). |
| ArgumentException | type does not inherit MulticastDelegate. -or- type is not a RuntimeType. See Runtime Types in Reflection. -or- method is not an instance method. -or- method cannot be bound; for example, because it cannot be found. |
| MissingMethodException | The Invoke method of type is not found. |
| MethodAccessException | The caller does not have access to method. -or- Application code attempts to access this member late-bound, for example, by using the Type.InvokeMember method. |
Remarks
This method 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.
In Silverlight, method must specify an accessible method.
This method overload is equivalent to calling the CreateDelegate(Type, Object, String, Boolean, Boolean) method overload, and specifying false for ignoreCase and true for throwOnBindFailure.
