- Anonymous methods allow you to define a code block where a "delegate" object is acceptable.
- An anonymous methods use the keyword "delegate", instead of name of the method. This is
followed by the body of the method.
- Anonymous method always start with the keyword "delegate" and which is followed by parameters to
be used inside the method & the method body itself.
- You can reduce the code by preventing instantiation of the delegate and registering delegate with
the methods.
- It increases the maintainability & readability of our code by keeping the caller
of the method & the method itself as close as possible to one another.
public MyForm()
{
Button btnSayHello = new Button();
btnSayHello.Text = "Hello";
btnSayHello.Click +=
delegate
{
MessageBox.Show("Hello!! User");
};
Controls.Add(btnSayHello);
}
Note:
- Anonymous methods are an easy or simplified way for you to assign handlers to the events. They
take less effort as compared to delegates & are closer to the events they are associated
with.
- An anonymous methods can't access the out or ref parameters of an outer scope.
- The anonymous-method-block can not access Unsafe code within it
- Method attributes can't be applied to Anonymous methods. Also an anonymous methods
can be added to the invocation list for delegates, but it can be only deleted from the invocation
list if they have been saved to the delegates.
