C# 将void（对象、DataReceivedEventArgs）传递给函数

我正在编写一个函数来创建一个进程并运行它

以下是原始函数：

public static void LaunchApplication(string runCommand, string commandArguments, string workingDir, string informMessage)
{
    try
    {
        Process applicationProcess = new Process();
        applicationProcess.StartInfo.FileName = runCommand;
        applicationProcess.StartInfo.WorkingDirectory = workingDir;
        applicationProcess.StartInfo.Arguments = commandArguments;
        applicationProcess.StartInfo.UseShellExecute = false;

        WriteHeadlineToConsole(informMessage);

        applicationProcess.Start();
        while (Process.GetProcesses().Any(runningProcess => runningProcess.Id == applicationProcess.Id)) { }

        WriteHeadlineToConsole("Finished " + informMessage);
    }
    catch (Exception ex)
    {
        Console.WriteLine(ex.Message);
        return;
    }
}

我想将函数的签名更改为：

public static void LaunchApplication(string runCommand, string commandArguments, string workingDir, string informMessage, Func<object, DataReceivedEventArgs> myMethodName)

applicationProcess.OutputDataReceived += new DataReceivedEventHandler(myMethodName);

可以这样做吗？

试试这个：

public static void LaunchApplication(string runCommand, string commandArguments, string workingDir, string informMessage, Action<string> redirectOutput, Action<string> redirectError)
{
    try
    {
        Process applicationProcess = new Process();
        applicationProcess.StartInfo.FileName = runCommand;
        applicationProcess.StartInfo.WorkingDirectory = workingDir;
        applicationProcess.StartInfo.Arguments = commandArguments;
        applicationProcess.StartInfo.UseShellExecute = false;
        applicationProcess.EnableRaisingEvents = true;
        applicationProcess.StartInfo.CreateNoWindow = true;

        if (redirectOutput != null)
            applicationProcess.OutputDataReceived += (s, data) => redirectOutput(data.Data);

        if (redirectError != null)
            applicationProcess.ErrorDataReceived += (sErr, errData) => redirectError(errData.Data);

        GeneralUtils.WriteHeadlineToConsole(informMessage);
        applicationProcess.Start();
        if (redirectOutput != null)
            applicationProcess.BeginOutputReadLine();
        if (redirectError != null)
            applicationProcess.BeginErrorReadLine();
        applicationProcess.WaitForExit();
        GeneralUtils.WriteHeadlineToConsole("Finished " + informMessage);
    }
    catch (Exception ex)
    {
        Console.WriteLine(ex.Message);
        return;
    }
}

PS： 下面的代码太糟糕了

AccessDeniedException

可能被抛出，CPU快疯了

while (Process.GetProcesses().Any(runningProcess => runningProcess.Id == applicationProcess.Id)) { }

使用

applicationProcess.WaitForExit（）取而代之
 在实现所有更改后，我测试了代码，但现在我得到了：
StandardOut尚未重定向或进程尚未启动。
尝试调用
applicationProcess.BeginOutputReadLine（）时出现异常。我用更改更新了您的代码。有什么想法吗？我看不到下面这行
applicationProcess.StartInfo.RedirectStandardOutput=true。我想这是需要的。我的错，忘了。再次非常感谢！！
while (Process.GetProcesses().Any(runningProcess => runningProcess.Id == applicationProcess.Id)) { }
