在Windows窗体应用程序的后台在cmd中运行命令

Question

I'm trying to run these commands in the cmd in the background of my program:

• Change into that directory and type 'svn log --xml -v > svn.log
• Change back to the c:\\statsvn directory
• type 'java -jar statsvn.jar c:\\myproject\\svn.log c:\\myproject'

I'm unsure where I should start but have tried this:

private void FileSelect_Click(object sender, EventArgs e)
    {
        string databaseDirectory = saveAndLoad.getFolderContentsFilename();
        FilePath.Text = databaseDirectory;
    }

    private void xmlGenerator_Click(object sender, EventArgs e)
    {
        string file = FilePath.ToString();
        var process = new Process();
        var startInfo = new ProcessStartInfo
        {
            WindowStyle = ProcessWindowStyle.Hidden,
            FileName = "path to your script file..."
        };

        process.StartInfo = startInfo;

        process.Start();
        process.WaitForExit();

        if (process.ExitCode == 0)
        {
            //success
        }
        else
        {
            //an error occured during script execution...
        }

    }

The overall aim of my code is to generate an xml file based on changes that have been committed to SVN the command lines that need to run should create an xml file. I'd like to do this in the background of the program without the cmd being displayed.

Any help would be great.

Thanks

Answer 1

You are trying to run program located in in a file at startInfo.FileName path, not your script. Save your script that you want to execute to a file, pass the path to the script file to your StartInfo object, start the process and wait for its execution:

var process = new Process();
var startInfo = new ProcessStartInfo
{
    WindowStyle = ProcessWindowStyle.Hidden,
    FileName = "path to your script file..."
};

process.StartInfo = startInfo;

process.Start();
process.WaitForExit();

if (process.ExitCode == 0)
{
    //success
}
else
{
    //an error occured during script execution...
}

I use the following function for any command, it always works: here you would need to pass two arguments. 1) your command and 2) your directory.

 private string BatchCommand(string cmd, string mapD)
    {
        Batchresults = "";

        System.Diagnostics.ProcessStartInfo procStartInfo = new System.Diagnostics.ProcessStartInfo("cmd", "/c " + cmd);
        procStartInfo.WorkingDirectory = mapD;
        // The following commands are needed to redirect the standard output.
        // This means that it will be redirected to the Process.StandardOutput StreamReader.
        procStartInfo.RedirectStandardOutput = true;
        procStartInfo.RedirectStandardError = true;
        procStartInfo.RedirectStandardInput = true;
        procStartInfo.UseShellExecute = false;
        // Do not create the black window.
        procStartInfo.CreateNoWindow = true;
        // Now we create a process, assign its ProcessStartInfo and start it
        System.Diagnostics.Process cmdProcess = new System.Diagnostics.Process();
        cmdProcess.StartInfo = procStartInfo;
        cmdProcess.ErrorDataReceived += cmd_Error;
        cmdProcess.OutputDataReceived += cmd_DataReceived;
        cmdProcess.EnableRaisingEvents = true;
        cmdProcess.Start();
        cmdProcess.BeginOutputReadLine();
        cmdProcess.BeginErrorReadLine();
        cmdProcess.StandardInput.WriteLine("exit");                  //Execute exit.
        cmdProcess.WaitForExit();

        // Get the output into a string

        return Batchresults;
    }
    static void cmd_DataReceived(object sender, DataReceivedEventArgs e)
    {
        if (e.Data != null)
            Batchresults += Environment.NewLine + e.Data.ToString();

    }

     void cmd_Error(object sender, DataReceivedEventArgs e)
    {
        if (e.Data != null)
        {
            Batchresults += Environment.NewLine + e.Data.ToString();

        }
    }

note that Batchresults is a global string.

call the script as

string result= BatchCommand("Your command here","Directory from where you want to execute it");

string result will contains details of all result and errors as well
