c# params

原文地址：點擊打開鏈接

每個C#函數都允許有個參數帶params關鍵字，在調用的時候可以不給他傳值，也可以給他傳值，還可以給他傳多個值，例子如下：

程序代碼

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

namespace ConsoleApplication1
{
 

   classProgram
    {
        staticvoid Main(string[] args)
        {
            Console.WriteLine(Test("Jack"));//不傳值，顯示Jack
            Console.WriteLine(Test("Jack","Hi"));//傳一個值，顯示Jack Hi
            Console.WriteLine(Test("Jack","Hi", "How are you?"));//傳多個值，顯示Jack Hi How are you?

            Console.ReadKey();
        }

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