Anonymous Methods

Added in .NET 2.0
These are superseded by Lambda Expressions

Anonymous methods allow you to define a delegate inline.
An anonymous method provides a way of passing a block of code as an argument instead of creating an explicit named method.
Use the delegate keyword to declare a delegate type first
A parameter is then passed to an anonymous method using the delegate keyword
no parameters

delegate void Delegate_Type(); 

Delegate_Type delegate_variable = delegate() 
{ // do something } 

instead of

delegate void Delegate_Type(); 

void Method_Name() 
{ // do something } 
Delegate_Type delegate_variable = Method_Name; 

with a parameter

delegate int Delegate_Type(int x); 

Delegate_Type delegate_variable = delegate(int paramater) 
{ return paremeter * parameter; } 

instead of

delegate int Delegate_Type(int x); 

int Method_Name(int parameter) 
{ return parameter * parameter; } 
Delegate_Type delegate_variable = Method_Name;
