C# Need to understand some of the technical (C# 需要懂的一些技术)

1. Anonymous Methods (匿名方法)

//example 1

delegate int MyAnonymityFunction();

private void CommonFunction()

{

     MyAnonymityFunction fun = delegate

    {

        return 7;

    }

    //anonymityValue value is 7

    int anonymityValue = fun();

}

//example 2

this.Button1.Click += delegate
{
    //input code
}

2. Lambda Expression (Lambda表达式)

List<int> listInt = new List<int>(){1,2,3,4,5,6,7,8};
//listEven value is 2,4,6,8
List<int> listEven = listInt.FindAll(i => i%2 == 0);
