C #에서 배치 파일 실행

C #에서 배치 파일 실행

---

C #에서 배치 파일을 실행하려고하는데 운이 좋지 않습니다.

인터넷에서 여러 가지 예제를 찾았지만 작동하지 않습니다.

public void ExecuteCommand(string command)
{
    int ExitCode;
    ProcessStartInfo ProcessInfo;
    Process Process;

    ProcessInfo = new ProcessStartInfo("cmd.exe", "/c " + command);
    ProcessInfo.CreateNoWindow = true;
    ProcessInfo.UseShellExecute = false;

    Process = Process.Start(ProcessInfo);
    Process.WaitForExit();

    ExitCode = Process.ExitCode;
    Process.Close();

    MessageBox.Show("ExitCode: " + ExitCode.ToString(), "ExecuteCommand");
}

명령 문자열에는 배치 파일 (에 저장 됨 system32) 의 이름 과 조작해야하는 일부 파일이 포함됩니다. (예 :) txtmanipulator file1.txt file2.txt file3.txt. 배치 파일을 수동으로 실행하면 올바르게 작동합니다.

코드를 실행할 때 나에게 **ExitCode: 1** (Catch all for general errors)

내가 뭘 잘못하고 있죠?

이 작동합니다. 무슨 일이 일어나고 있는지 확인하기 위해 출력 및 오류 스트림의 내용을 덤프 할 수 있습니다.

static void ExecuteCommand(string command)
{
    int exitCode;
    ProcessStartInfo processInfo;
    Process process;

    processInfo = new ProcessStartInfo("cmd.exe", "/c " + command);
    processInfo.CreateNoWindow = true;
    processInfo.UseShellExecute = false;
    // *** Redirect the output ***
    processInfo.RedirectStandardError = true;
    processInfo.RedirectStandardOutput = true;

    process = Process.Start(processInfo);
    process.WaitForExit();

    // *** Read the streams ***
    // Warning: This approach can lead to deadlocks, see Edit #2
    string output = process.StandardOutput.ReadToEnd();
    string error = process.StandardError.ReadToEnd();

    exitCode = process.ExitCode;

    Console.WriteLine("output>>" + (String.IsNullOrEmpty(output) ? "(none)" : output));
    Console.WriteLine("error>>" + (String.IsNullOrEmpty(error) ? "(none)" : error));
    Console.WriteLine("ExitCode: " + exitCode.ToString(), "ExecuteCommand");
    process.Close();
}

static void Main()
{
    ExecuteCommand("echo testing");
}   

* 편집하다 *

아래에 귀하의 의견에 추가 정보가 있으면 문제를 재현 할 수있었습니다. 이 동작을 일으키는 보안 설정이있는 것 같습니다 (자세한 내용은 조사하지 않았습니다).

This does work if the batch file is not located in C:\Windows\System32. Try moving it to some other location, e.g. the location of your executable. Note that keeping custom batch files or executables in the Windows directory is bad practice anyway.

* EDIT 2 * It turns out that if the streams are read synchronously, a deadlock can occur, either by reading synchronously before WaitForExit or by reading both stderr and stdout synchronously one after the other.

This should not happen if using the asynchronous read methods instead, as in the following example:

static void ExecuteCommand(string command)
{
    var processInfo = new ProcessStartInfo("cmd.exe", "/c " + command);
    processInfo.CreateNoWindow = true;
    processInfo.UseShellExecute = false;
    processInfo.RedirectStandardError = true;
    processInfo.RedirectStandardOutput = true;

    var process = Process.Start(processInfo);

    process.OutputDataReceived += (object sender, DataReceivedEventArgs e) =>
        Console.WriteLine("output>>" + e.Data);
    process.BeginOutputReadLine();

    process.ErrorDataReceived += (object sender, DataReceivedEventArgs e) =>
        Console.WriteLine("error>>" + e.Data);
    process.BeginErrorReadLine();

    process.WaitForExit();

    Console.WriteLine("ExitCode: {0}", process.ExitCode);
    process.Close();
}

System.Diagnostics.Process.Start("c:\\batchfilename.bat");

this simple line will execute the batch file.

After some great help from steinar this is what worked for me:

public void ExecuteCommand(string command)
{
    int ExitCode;
    ProcessStartInfo ProcessInfo;
    Process process;

    ProcessInfo = new ProcessStartInfo(Application.StartupPath + "\\txtmanipulator\\txtmanipulator.bat", command);
    ProcessInfo.CreateNoWindow = true;
    ProcessInfo.UseShellExecute = false;
    ProcessInfo.WorkingDirectory = Application.StartupPath + "\\txtmanipulator";
    // *** Redirect the output ***
    ProcessInfo.RedirectStandardError = true;
    ProcessInfo.RedirectStandardOutput = true;

    process = Process.Start(ProcessInfo);
    process.WaitForExit();

    // *** Read the streams ***
    string output = process.StandardOutput.ReadToEnd();
    string error = process.StandardError.ReadToEnd();

    ExitCode = process.ExitCode;

    MessageBox.Show("output>>" + (String.IsNullOrEmpty(output) ? "(none)" : output));
    MessageBox.Show("error>>" + (String.IsNullOrEmpty(error) ? "(none)" : error));
    MessageBox.Show("ExitCode: " + ExitCode.ToString(), "ExecuteCommand");
    process.Close();
}

It works fine. I tested it like this:

String command = @"C:\Doit.bat";

ProcessInfo = new ProcessStartInfo("cmd.exe", "/c " + command);
// ProcessInfo.CreateNoWindow = true;

I commented out turning off the window so I could SEE it run.

Below code worked fine for me

using System.Diagnostics;

public void ExecuteBatFile()
{
    Process proc = null;

    string _batDir = string.Format(@"C:\");
    proc = new Process();
    proc.StartInfo.WorkingDirectory = _batDir;
    proc.StartInfo.FileName = "myfile.bat";
    proc.StartInfo.CreateNoWindow = false;
    proc.Start();
    proc.WaitForExit();
    ExitCode = proc.ExitCode;
    proc.Close();
    MessageBox.Show("Bat file executed...");
}

---

using System.Diagnostics;

private void ExecuteBatFile()
{
    Process proc = null;
    try
    {
        string targetDir = string.Format(@"D:\mydir");   //this is where mybatch.bat lies
        proc = new Process();
        proc.StartInfo.WorkingDirectory = targetDir;
        proc.StartInfo.FileName = "lorenzo.bat";
        proc.StartInfo.Arguments = string.Format("10");  //this is argument
        proc.StartInfo.CreateNoWindow = false;
        proc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;  //this is for hiding the cmd window...so execution will happen in back ground.
        proc.Start();
        proc.WaitForExit();
    }
    catch (Exception ex)
    {
        Console.WriteLine("Exception Occurred :{0},{1}", ex.Message, ex.StackTrace.ToString());
    }
}

Have you tried starting it as an administrator? Start Visual Studio as an administrator if you use it, because working with .bat files requires those privileges.

I wanted something that was more directly usable without organization-specific hard-coded string values in it. I offer the following as a directly reusable chunk of code. The minor downside is needing to determine and pass the working folder when making the call.

public static void ExecuteCommand(string command, string workingFolder)
        {
            int ExitCode;
            ProcessStartInfo ProcessInfo;
            Process process;

            ProcessInfo = new ProcessStartInfo("cmd.exe", "/c " + command);
            ProcessInfo.CreateNoWindow = true;
            ProcessInfo.UseShellExecute = false;
            ProcessInfo.WorkingDirectory = workingFolder;
            // *** Redirect the output ***
            ProcessInfo.RedirectStandardError = true;
            ProcessInfo.RedirectStandardOutput = true;

            process = Process.Start(ProcessInfo);
            process.WaitForExit();

            // *** Read the streams ***
            string output = process.StandardOutput.ReadToEnd();
            string error = process.StandardError.ReadToEnd();

            ExitCode = process.ExitCode;

            MessageBox.Show("output>>" + (String.IsNullOrEmpty(output) ? "(none)" : output));
            MessageBox.Show("error>>" + (String.IsNullOrEmpty(error) ? "(none)" : error));
            MessageBox.Show("ExitCode: " + ExitCode.ToString(), "ExecuteCommand");
            process.Close();
        }

Called like this:

    // This will get the current WORKING directory (i.e. \bin\Debug)
    string workingDirectory = Environment.CurrentDirectory;
    // This will get the current PROJECT directory
    string projectDirectory = Directory.GetParent(workingDirectory).Parent.FullName;
    string commandToExecute = Path.Combine(projectDirectory, "TestSetup", "WreckersTestSetupQA.bat");
    string workingFolder = Path.GetDirectoryName(commandToExecute);
    commandToExecute = QuotesAround(commandToExecute);
    ExecuteCommand(commandToExecute, workingFolder);

In this example, from within Visual Studio 2017, as part of a test run, I want to run an environment reset batch file before executing some tests. (SpecFlow+xUnit). I got tired of extra steps for manually running the bat file separately, and wanted to just run the bat file as part of the C# test setup code. The environment reset batch file moves test case files back into the input folder, cleans up output folders, etc. to get to the proper test starting state for testing. The QuotesAround method simply puts quotes around the command line in case there are spaces in folder names ("Program Files", anyone?). All that's in it is this: private string QuotesAround(string input) {return "\"" + input + "\"";}

Hope some find this useful and save a few minutes if your scenario is similar to mine.

System.Diagnostics.Process.Start(BatchFileName, Parameters);

I know this will work for batch file and parameters, but no ideas how to get the results in C#. Usually, the outputs are defined in the batch file.
