22.6 Delegates

The syntax for a delegate in C# closely follows the syntax for a method. The delegate statement is followed by the delegate's return type (or void, if there is none) and the delegate name. This in turn is followed by the delegate's parameter list, in which each parameter takes the form:

<parameter_type> <parameter_name>

For example:

public delegate void StateChangeEventHandler(object sender,
   StateChangeEventArgs e);

In a VB Delegate statement, the Delegate keyword is followed by the Sub keyword (if the delegate returns a void in C#) or the Function keyword (if the delegate returns some other value). For example, in VB, the StateChangeEventHandler delegate has the following syntax:

Public Delegate Sub StateChangeEventHandler( _
   ByVal sender As Object, ByVal e As StateChangeEventArgs)
