Public Shared Function CreateDelegate ( _

[SecuritySafeCriticalAttribute]

    bool ignoreCase,
    bool throwOnBindFailure
)

Parameters

type
Type: System.Type
The type of delegate to create.

target
Type: System.Type
The class that implements method.

method
Type: System.String
The name of the static method that the delegate is to represent.

ignoreCase
Type: System.Boolean
true to ignore the case when comparing the name of the method; otherwise, false.

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- target is not a RuntimeType. -or- target is an open generic type. That is, its ContainsGenericParameters property is true. -or- method is not a static method (Shared method in Visual Basic). -or- method cannot be bound; for example, because it cannot be found, and throwOnBindFailure is true.
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 static 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.

Platform Notes

Silverlight for Windows Phone

CreateDelegate throws MissingMethodException when attempting to create a delegate with incorrect arguments. Delegate.CreateDelegate throws TargetInvocationException when called on a null object. Delegate.CreateDelegate throws MissingMethodException instead of ArgumentException for non-instance methods.
