Namespace: System
Assembly: mscorlib (in mscorlib.dll)

Syntax

'Declaration
Public Shared Function CreateDelegate ( _
    type As Type, _
    target As Type, _
    method As String, _
    ignoreCase As Boolean _
) As Delegate

public static Delegate CreateDelegate(

    Type target,
    string method,
    bool ignoreCase
)

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.

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.
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.

This method overload is equivalent to calling the CreateDelegate(Type, Type, String, Boolean, Boolean) method overload, and specifying true for throwOnBindFailure.

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.
