刚学C#,照书上打了一个例子没有结果

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

public class Test
{
public static void Main(string[] args)
{
Console.WriteLine("Hello,World");
Console.WriteLine("Yor entered the following {0} commend:",args.Length);
for(int i=0;i<args.Length;i++)
{
Console.WriteLine("{0}",args[i]);
}
}
}

没有结果,For也没有执行,怎么回事?
