我正在尝试在文件中运行命令行程序和管道。该命令在命令行上工作正常,但是我似乎无法使其与C#中的Process对象一起使用。这是我发出的命令:

“C:\Servers\CollabNet Subversion Server\svnadmin”加载C:\Repositories\TestLoad
此功能与我传递给它的所有其他命令均能正常工作,但上面的命令除外:

public static bool ExecuteSvnCommand( string command, string arguments, out string result, out string errors )
{
    bool retval = false;
    string output = string.Empty;
    string errorLines = string.Empty;
    Process svnCommand = null;
    var psi = new ProcessStartInfo( command );

    psi.RedirectStandardOutput = true;
    psi.RedirectStandardError = true;
    psi.WindowStyle = ProcessWindowStyle.Hidden;
    psi.UseShellExecute = false;
    psi.CreateNoWindow = true;

    try
    {
        Process.Start( psi );
        psi.Arguments = arguments;
        svnCommand = Process.Start( psi );

        StreamReader myOutput = svnCommand.StandardOutput;
        StreamReader myErrors = svnCommand.StandardError;
        svnCommand.WaitForExit();

        if ( svnCommand.HasExited )
        {
            output = myOutput.ReadToEnd();
            errorLines = myErrors.ReadToEnd();
        }

        // Check for errors
        if ( errorLines.Trim().Length == 0 )
        {
            retval = true;
        }
    }
    catch ( Exception ex )
    {
        string msg = ex.Message;
        errorLines += Environment.NewLine + msg;
    }
    finally
    {
        if (svnCommand != null)
        {
            svnCommand.Close();
        }
    }

    result = output;
        errors = errorLines;

    return retval;
}

我已经尝试了此功能的几种不同组合,但是无法正常工作。我不断收到“系统找不到指定的文件”消息。我已经在这里待了大约一个星期,我想我需要一些眼睛才能看到我做错了什么。

最佳答案

马克和卢克都给了我正确的方向。我不能使用任何一个答案,因为我必须这样做,以便它可以在Linux中与Mono一起运行。因此,我最终按照建议写了StandardInput。这是有效的代码:

public static bool ExecuteSvnCommandWithFileInput( string command, string arguments, string filePath, out string result, out string errors )
{
    bool retval = false;
    string output = string.Empty;
    string errorLines = string.Empty;
    Process svnCommand = null;
    var psi = new ProcessStartInfo( command );

    psi.RedirectStandardInput = true;
    psi.RedirectStandardOutput = true;
    psi.RedirectStandardError = true;
    psi.WindowStyle = ProcessWindowStyle.Hidden;
    psi.UseShellExecute = false;
    psi.CreateNoWindow = true;

    try
    {
        Process.Start( psi );
        psi.Arguments = arguments;
        svnCommand = Process.Start( psi );

        var file = new FileInfo(filePath);
        StreamReader reader = file.OpenText();
        string fileContents = reader.ReadToEnd();
        reader.Close();

        StreamWriter myWriter = svnCommand.StandardInput;
        StreamReader myOutput = svnCommand.StandardOutput;
        StreamReader myErrors = svnCommand.StandardError;

        myWriter.AutoFlush = true;
        myWriter.Write(fileContents);
        myWriter.Close();

        output = myOutput.ReadToEnd();
        errorLines = myErrors.ReadToEnd();

        // Check for errors
        if ( errorLines.Trim().Length == 0 )
        {
            retval = true;
        }
    }
    catch ( Exception ex )
    {
        string msg = ex.Message;
        errorLines += Environment.NewLine + msg;
    }
    finally
    {
        if (svnCommand != null)
        {
            svnCommand.Close();
        }
    }

    result = output;
    errors = errorLines;

    return retval;
}
