Represents an expression that creates a delegate.
Assembly: System (in System.dll)
Thetype exposes the following members.
|CodeDelegateCreateExpression()||Initializes a new instance of the class.|
|CodeDelegateCreateExpression(CodeTypeReference, CodeExpression, String)||Initializes a new instance of the class.|
|Equals(Object)||Determines whether the specified object is equal to the current object. (Inherited from Object.)|
|Finalize||Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)|
|GetHashCode||Serves as the default hash function. (Inherited from Object.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
The DelegateType property specifies the type of delegate to create. The TargetObject property indicates the object that contains the event-handler method. The MethodName property indicates the name of the event-handler method whose method signature matches the method signature of the delegate.
In C#, a delegate creation expression is typically of the following form: new EventHandler(this.HandleEventMethod). In Visual Basic, a delegate creation expression is typically of the following form: AddressOf Me.HandleEventMethod.
The following example code uses a to create a delegate.
// Defines a delegate creation expression that creates an EventHandler delegate pointing to a method named TestMethod. CodeDelegateCreateExpression^ createDelegate1 = gcnew CodeDelegateCreateExpression( gcnew CodeTypeReference( "System.EventHandler" ),gcnew CodeThisReferenceExpression,"TestMethod" ); // Attaches an EventHandler delegate pointing to TestMethod to the TestEvent event. CodeAttachEventStatement^ attachStatement1 = gcnew CodeAttachEventStatement( gcnew CodeThisReferenceExpression,"TestEvent",createDelegate1 ); // A C# code generator produces the following source code for the preceeding example code: // this.TestEvent += new System.EventHandler(this.TestMethod);
