在C＃中将字符串作为批处理文件运行

Question

I'm writing an application that creates a batch file and then run :

I know I can create a Batch file and run it no problem with that .

What I want to do is : once I have created the string that makes the file , Is there is any way to execute the string as a Batch file ? something like

string BatchFile = "echo \"bla bla\" \n iperf -c 123  ... ... .. "
Diagnostics.Process.Start(BatchFile);

Answer 1

您可以使用/ c作为可执行文件来运行CMD.EXE ，并将其余部分作为参数：

Process.Start("cmd.exe", "/c echo \"bla bla\" \n iperf -c 123  ... ... .. ");

for me, I am using this code:

Process process;
        private void button1_Click(object sender, EventArgs e)
        {
            process = new Process();
            process.StartInfo.UseShellExecute = false;
            process.StartInfo.FileName = "cmd";
            process.StartInfo.RedirectStandardOutput = true;
            process.StartInfo.RedirectStandardInput = true;
            process.Start();
            BackgroundWorker worker = new BackgroundWorker();
            worker.DoWork += new DoWorkEventHandler(worker_DoWork);
            worker.RunWorkerAsync();

            process.StandardInput.WriteLine("cd d:/tempo" );
            process.StandardInput.WriteLine("dir");



        }
        void worker_DoWork(object sender, DoWorkEventArgs e)
        {
            string line;
            while (!process.StandardOutput.EndOfStream)
            {
                line = process.StandardOutput.ReadLine();
                if (!string.IsNullOrEmpty(line))
                {
                    SetText(line);
                }
            }
        }

        delegate void SetTextCallback(string text);
        private void SetText(string text)
        {
            if (this.textBox1.InvokeRequired)
            {
                SetTextCallback d = new SetTextCallback(SetText);
                this.Invoke(d, new object[] { text });
            }
            else
            {
                this.textBox1.Text += text + Environment.NewLine;
            }
        }
        private void FrmMain_FormClosing(object sender, FormClosingEventArgs e)
        {
            process.StandardInput.WriteLine("exit");
            process.Close();

        }

You may create your Batch "file" as a long string with lines terminated in \\n , exactly as you shown in your example, and then execute that string (I called it a "NotBatch-text") executing cmd.exe and redirecting such string into its Stdin standard handle. This way, your "NotBatch-text" may use a large number of Batch features, like expansion of %variables%, IF and FOR commands nested at any level, and many more. You may also use delayed !variable! expansion if you execute cmd.exe with /V:ON switch. Really, the only things that don't works in the NotBatch-text are: parameters and SHIFT command, and GOTO / CALL :label commands; further details at this post .

If you want to execute a more advanced "NotBatch-text" string, you may even simulate GOTO and CALL :label commands with the aid of a third party program, as described at this post .
