在windows窗体应用程序的背景中运行cmd中的命令。

Question

我试图在我的程序背景下的cmd中运行这些命令：

• 切换到该目录并键入'svn log --xml -v > svn.log
• 更改回c:\statsvn目录
• 键入'java -jar statsvn.jar c:\myproject\svn.log c:\myproject‘

我不知道该从哪里开始，但我试过这样做：

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...
        }

    }

我的代码的总体目标是根据提交给SVN的更改生成一个xml文件，需要运行的命令行应该创建一个xml文件。我想在没有显示cmd的情况下在程序的背景中这样做。

任何帮助都会很好。

谢谢

您正在尝试运行位于startInfo.FileName路径的文件中的程序，而不是脚本。将要执行的脚本保存到文件中，将脚本文件的路径传递给StartInfo对象，启动进程并等待其执行：

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...
}

对于任何命令，我都使用以下函数，它总是有效的:这里需要传递两个参数。1)你的命令和2)你的目录。

 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();

        }
    }

注意，Batchresults是一个全局字符串。

调用脚本为

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

字符串结果将包含所有结果和错误的详细信息。
