using System.Diagnostics;
using System.IO;

        public static string CommandOutput(string commandText)
        {
            System.Diagnostics.Process p = new System.Diagnostics.Process();
            p.StartInfo.FileName = "cmd.exe";
            p.StartInfo.UseShellExecute = false;
            p.StartInfo.RedirectStandardInput = true;
            p.StartInfo.RedirectStandardOutput = true;
            p.StartInfo.RedirectStandardError = true;
            p.StartInfo.CreateNoWindow = true; //不跳出cmd視窗
            string strOutput = null;

            try
            {
                p.Start();

                p.StandardInput.WriteLine(commandText);
                p.StandardInput.WriteLine("exit");
                strOutput = p.StandardOutput.ReadToEnd();//匯出整個執行過程                p.WaitForExit();
                p.Close();

            }
            catch (Exception e)
            {
                strOutput = e.Message;
            }
            return strOutput;
        }

 p.StandardInput 也可以配合StreamWriter做批次執行 例如：

                StreamWriter sw = p.StandardInput;
                sw.WriteLine("dir /w");
                sw.WriteLine(@"cd d:\test");
                sw.WriteLine(@"copy *.* c:\test");
                sw.Close(); 

或是匯出之txt檔案 例如：

        // 1: Write single line to new file
        using (StreamWriter sw = new StreamWriter("C:\\log.txt", true))
        {
            sw.WriteLine("Important data line 1");
        }
        // 2: Append line to the file
        using (StreamWriter sw = new StreamWriter("C:\\log.txt", true))
        {
            sw.WriteLine("Line 2");
        }

出來的結果會遞增至log.txt如下所示：

Important data line 1
Line 2
