在VS 2010的C#控制台应用程序中,我有......
static void Main(string[] args)
{
Console.WriteLine("Welcome to c#");
Console.WriteLine(DownloadPOS());
当我点击播放时打开命令提示符,显示“欢迎使用c#”并运行“DownloadPOS”功能。
我想删除Console.WriteLine(DownloadPOS());
,运行程序并且必须在命令行中手动输入文本'DownloadPOS()'。我怎样才能做到这一点?我尝试打开cmd并导航到项目。?
我也尝试右键单击项目/ properties / debug并在命令行参数中输入DownloadPOS()并在debug中运行项目。这应该运行吗?

你想做这样的事情:
static void Main(string[] args)
{
Console.WriteLine("Welcome to c#");
Console.WriteLine("Please select an option.\n");
Console.WriteLine("Select D for DownLoadPos(), U for UpLoadPos() ...\n");
string input = Console.ReadLine();
switch(input)
{
case "D":
{
DownloadPOS();
break;
}
case "U":
{
//UpLoadPOS(); // This is not a real method. Just for explanation
break;
}
default:
{
Console.WriteLine("You have not selected an option.\n");
Console.WriteLine("The program will now exit. \n");
System.Threading.Thread.Sleep(1000);
break;
}
}
}

class Program
{
static void Main(string[] args)
{
Console.WriteLine("Welcome to c#");
// Example 1
if (args.Count() > 0 && args[0].ToUpper().Equals("DOWNLOADPOS1"))
{
Console.WriteLine("Called via Arguments");
DownloadPOS();
}
// Example 2
else if ("DOWNLOADPOS2" == Console.ReadLine().ToUpper())
{
Console.WriteLine("Called via user input");
DownloadPOS();
}
// To stop command prompt disappearing
Console.ReadLine();
}
private static void DownloadPOS()
{
Console.WriteLine("Hello from DownloadPOS");
}
}
如果您将DOWNLOADPOS1作为参数,程序将调用您的方法。输出将是;
欢迎来到c#
通过参数调用
您好,来自DownloadPOS
如果删除命令行参数然后运行程序,它将等待您的输入。输入" DOWNLOADPOS2"并且它将执行您的方法。命令提示符就像;
欢迎来到c#
DOWNLOADPOS2
通过用户输入进行调用
您好,来自DownloadPOS
