Passing arguments to a .cmd file in C#

问题

I have a .cmd file which asks the user for an input, based on which further steps are performed. I am trying to write a program to automate this process in C# such that command prompt runs in the background(without popping up to the user/eliminating all user interaction) and the arguments get passed. I have referred to multiple answers, however did not find a solution. I have already referred the links below.

Passing cmd line arguments to specific method

Passing Cmd Command to C# Application

Passing c# command line arguments in a batch file

It would be great if anyone could point me in the right direction.

回答1:

1) Try edit your bat/cmd for receive arguments thought in C#:

args[] in c# is %1,%2,%n... in bat/cmd

2) You need edit your bat/cmd to receive your C# arguments:

Console.ReadLine() in c# is set /p some_var_by_input= in bat/cmd
- Edit in the bat/cmd file, wherever you need: set / p input_1 =" Enter some entry: "
- Remove and add the appropriate treatment to your arguments:
```
set /p input_1="Enter some input:"
set input_1=%~1
```
- If there is more than one argument, just increase like...
```
set "input_2=%~2"
set "input_n=%~n"
```

Here is sample c# code that are sending 2 arguments to a bat/cmd file

using System;
using System.Diagnostics;

namespace ConsoleApplication
{
    class Program
    { 
        static void Main(string[] args)
        {
         System.Diagnostics.Process.Start(@"c:\batchfilename.bat", "\"1st\" \"2nd\"");
        }
    }
}

Obs.: c# sources from @T.S.Sathish answer here

The bat file code using %1 & %2 arguments passed from C #:

@echo off 
%__APPDIR__%mode.com con: cols=60 lines=6
echo/
echo/  your arg_CS[0] == arg_bat[%%1] == %1
echo/  your arg_CS[1] == arg_bat[%%2] == %2
echo/ ________________________________________________________
echo/ Please, press any key for me got to go drink a coffe...
@%__APPDIR__%timeout.exe -1 >nul

bat/cmd outputs:

Option 2 : Hiding the console window, passing arguments and taking outputs

This is an edit from this answer /by @Brian Rasmussen

using System;
using System.Diagnostics;

namespace ConsoleApplication
{
    class Program
    { 
        static void Main(string[] args)
        {
         var process = new Process();
         var startinfo = new ProcessStartInfo(@"c:\batchfilename.bat", "\"1st_arg\" \"2nd_arg\" \"3rd_arg\"");
         startinfo.RedirectStandardOutput = true;
         startinfo.UseShellExecute = false;
         process.StartInfo = startinfo;
         process.OutputDataReceived += (sender, argsx) => Console.WriteLine(argsx.Data); // do whatever processing you need to do in this handler
         process.Start();
         process.BeginOutputReadLine();
         process.WaitForExit();
        }
    }
}

_{This is based on my limited understanding of English so if that is not correct, sorry, and if possible, please let me know ...}
