如何从命令提示符处获取参数并运行应用程序 [英] how to get arguments from command prompt and to run the application

问题描述

我有一个要求，我的c#windows应用程序中有一个函数，该函数的参数应从命令提示符处获取然后执行程序.

在此先感谢

解决方案

如果您使用的是控制台应用程序，则main方法应将字符串数组作为包含所有参数的参数.

例如.下面的代码显示所有命令行参数.

class TestClass
{
    static void Main(string[] args)
    {
        // Display the number of command line arguments:
        System.Console.WriteLine(args.Length);
    }
}

 字符串 [] System.Environment.GetCommandLineArgs()

Main的参数是命令行参数.如果您使用的是标准Visual Studio模板，则可以在Program.cs中找到Main方法.如果我在Windows应用程序中需要它们，则通常会修改Main方法，以将参数数组传递到主窗体的构造函数中，然后在其中进行处理.

Ralphlee1的答案也是正确的，但我更希望从单个入口点将它们作为参数传递，因为那样看起来更干净，因为外部信息仅在单个位置输入.

i have a requirement such that there is a function in my c#windows application arguments to that function should get from command prompt and then execute the program .how to do that??


thanks in advance

解决方案

If you are using a console application, the main method woould have a string array as a parameter that would contain all the parameters.

E.g. The code below displays all the command line arguments.

class TestClass
{
    static void Main(string[] args)
    {
        // Display the number of command line arguments:
        System.Console.WriteLine(args.Length);
    }
}

string[] System.Environment.GetCommandLineArgs()

The arguments to Main are the command line arguments. If you''re using the standard Visual Studio template, you can find the Main method in Program.cs. If I need them in a Windows application I generally modify that Main method to pass the array of arguments into the main form''s constructor, and handle them in there.

Ralphlee1''s answer is also correct but I prefer to pass them as arguments from the single entry point because that seems cleaner, as the external information is only being fed in in a single place.
