您需要重定向进程的输入和输出：

using System;
using System.IO;
using System.Diagnostics;

namespace ProcessStandardInputSample
{
    class StandardInputTest
    {
        static void Main()
        {
            using (Process myProcess = new Process())
            {
                myProcess.StartInfo.FileName = "text.bat";
                myProcess.StartInfo.UseShellExecute = false;
                myProcess.StartInfo.RedirectStandardInput = true;
                myProcess.StartInfo.RedirectStandardOutput = true;
                myProcess.Start();
                StreamWriter myStreamWriter = myProcess.StandardInput;
                myStreamWriter.WriteLine("test");
                Console.WriteLine(myProcess.StandardOutput.ReadToEnd());
                myProcess.WaitForExit();
            }
        }
    }
}

你可以在ProcessStartInfo.RedirectStandardInput Property和ProcessStartInfo.RedirectStandardOutput Property中找到很好的解释。

这可能对你有帮助

ProcessStartInfo processInfo;
Process process;

processInfo = new ProcessStartInfo("path to batch" );
processInfo.CreateNoWindow = true;
processInfo.UseShellExecute = false;

processInfo.RedirectStandardOutput = true;

process = Process.Start(processInfo);
string output = process.StandardOutput.ReadToEnd();
Console.WriteLine(output);
process.WaitForExit();

process.Close();
