Which of the N types of delegation statements do you like?

1. Original Version:

      PlusStringHandle( x,   Main(= ,   plusString( x,  x +

2. Original anonymous function version: remove the "plusString" method and change it

            PlusStringHandle pHandle =  PlusStringHandle(( x,  x +, ));

3. Use Lambda (C #3.0 +) and remove the "plusString" method (this method is not required for the following code)

            PlusStringHandle pHandle = ( x,  y) => x +, ));

There are even more ways to write (saving parameter types)

            PlusStringHandle pHandle = (x, y) => x +, ));

If there is only one parameter

          WriteStringHandle(  Main(            WriteStringHandle handle = p =>

 

1. For the original declaration method, see Demo2. directly use the generic delegate Func AND Action defined by. NET Framework to save the delegate declaration every time.

          Main(<>(p => Console.WriteLine(, p),   WritePrint<T>(Action<T>

3. Add an extension method to implement the so-called "chain programming.

      Main( str = .plusString(p => p = p + ).plusString(p => p +     plusString<TParam>( TParam source, Func<TParam, >
