Anonymous method C# with Example

Anonymous methods provide a technique to pass a code block as a delegate parameter. They are methods with a 
body, but no name. 
delegate int IntOp(int lhs, int rhs); 
class Program 
{ 
static void Main(string[] args) 
{ 
// C# 2.0 definition 
IntOp add = delegate(int lhs, int rhs) 
{ 
return lhs + rhs; 
}; 
// C# 3.0 definition 
IntOp mul = (lhs, rhs) => 
{ 
return lhs * rhs; 
}; 
// C# 3.0 definition - shorthand 
IntOp sub = (lhs, rhs) => lhs - rhs; 
//   Calling   each   method 
Console.WriteLine("2 + 3 = " + add(2, 3)); 
Console.WriteLine("2 * 3 = " + mul(2, 3)); 
 

Console.WriteLine("2 - 3 = " + sub(2, 3)); 
} 
}
