c# params

原文地址：点击打开链接

每个C#函数都允许有个参数带params关键字，在调用的时候可以不给他传值，也可以给他传值，还可以给他传多个值，例子如下：

程序代码

using System;
using System.Collections.Generic;
using System.Text;

namespace ConsoleApplication1
{
 

   classProgram
    {
        staticvoid Main(string[] args)
        {
            Console.WriteLine(Test("Jack"));//不传值，显示Jack
            Console.WriteLine(Test("Jack","Hi"));//传一个值，显示Jack Hi
            Console.WriteLine(Test("Jack","Hi", "How are you?"));//传多个值，显示Jack Hi How are you?

            Console.ReadKey();
        }

        staticstring Test(string name, params string[] args)
        {
            stringmsg = name;
