// Defines a delegate creation expression that creates an EventHandler delegate pointing to a method named TestMethod.

CodeDelegateCreateExpression createDelegate1 = new CodeDelegateCreateExpression(

new CodeTypeReference("System.EventHandler"), new CodeThisReferenceExpression(), "TestMethod");

// Attaches an EventHandler delegate pointing to TestMethod to the TestEvent event.

CodeAttachEventStatement attachStatement1 = new CodeAttachEventStatement(new CodeThisReferenceExpression(), "TestEvent", createDelegate1);

// A C# code generator produces the following source code for the preceeding example code:

// this.TestEvent += new System.EventHandler(this.TestMethod);
