C#检查您是否传递了参数 [英] C# check if you have passed arguments or not

问题描述

我有此代码:

public static void Main(string[] args)
{         
    if (string.IsNullOrEmpty(args[0]))  // Warning : Index was out of the bounds of the array
    {
        ComputeNoParam cptern = new ComputeNoParam();
        cptern.ComputeWithoutParameters();
    }
    else
    {
        ComputeParam cpter = new ComputeParam();
        foreach (string s in args){...}
    }
}

还尝试了 if(args.Length == 0)，但仍然无法正常工作.

Also tried if(args.Length==0), but it still doesn't work.

基本上，我想确定用户是否使用参数调用了该程序.如果没有，程序将要求输入.

Basically I want to find out if the user called the program with arguments. If not the program will ask for input.

我该怎么做?预先感谢.

How can I do this? Thanks in advance.

推荐答案

if(args.Length == 0)应该起作用， args [0] 至少需要一个不崩溃的论点.

if(args.Length==0) should work, args[0] requires at least one argument to not crash.
