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){...}
    }
}

也试过if(args.Length == 0),但它仍然不起作用.

基本上我想知道用户是否用参数调用程序.如果程序没有要求输入.

我该怎么做？@H_403_9@提前致谢.
