delegate type

The return type and parameter types of a delegate type must be at least as accessible as the delegate type itself.

A delegate type whose signature matches that of the dynamic method, minus the first parameter.

Generic delegates also can be used in dynamically generated code without requiring the generation of a delegate type .

Once a delegate type has been declared, a delegate object must be created and associated with a particular method.

In this example, the value of r is 20, just like the previous example where we assigned the lambda directly to a delegate type.

After a delegate type has been declared, a delegate object must be created and associated with a particular method.

Whenever a new set of argument types or return value type is needed, a new delegate type must be declared.

You can use the delegate type to declare a variable that can refer to any method with the same signature as the delegate.

A delegate type represents references to methods with a particular parameter list and return type.

Not all the non-null entries in delegates are instances of the same delegate type.

The declaration of a delegate type establishes a contract that specifies the signature of one or more methods.

Each delegate type describes the number and types of the arguments, and the type of the return value of methods that it can encapsulate.

The Click event uses the EventHandler class for the delegate type and the EventArgs class for the event data.

In some situations, you may want to declare an event to use an existing delegate type as its underlying delegate.

This constructs a new instance of the delegate type using the constructor MyDelegate(object, IntPtr).

It is also not permissible to derive a new type from a delegate type.

This method is static (Shared in Visual Basic), so the delegate type must be supplied.

Visual Basic cannot implement an event because the delegate type of the event does not match the delegate type of another event.
