Delegate Constructor (Object, String)

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Updated: June 2010

Initializes a delegate that invokes the specified instance method on the specified class instance.

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

Syntax

'Declaration
<SecuritySafeCriticalAttribute> _
Protected Sub New ( _
    target As Object, _
    method As String _
)
[SecuritySafeCriticalAttribute]
protected Delegate(
    Object target,
    string method
)

Parameters

  • target
    Type: System.Object
    The class instance on which the delegate invokes method.
  • method
    Type: System.String
    The name of the instance method that the delegate represents.

Exceptions

Exception Condition
ArgumentNullException

target is nulla null reference (Nothing in Visual Basic).

-or-

method is nulla null reference (Nothing in Visual Basic).

ArgumentException

There was an error binding to the target method.

MethodAccessException

Application code attempts to access this member late-bound, for example, by using the Type.InvokeMember method.

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.
