Question

运行Git diff会卡住，直到作为System.Diagnostics.Process运行时被杀死。

代码：

class Program
    {
        static void Main(string[] args)
        {
            ProcessStartInfo pInfo = new ProcessStartInfo();
            pInfo.FileName = "git.exe";
            pInfo.Arguments = "diff --name-only --exit-code V2.4-Beta-01 HEAD";
            pInfo.WorkingDirectory = @"C:\Git";
            pInfo.UseShellExecute = false;
            pInfo.CreateNoWindow = true;
            pInfo.RedirectStandardError = true;
            pInfo.RedirectStandardOutput = true;

            Process p = new Process();
            p.StartInfo = pInfo;

            p.Start();

            p.WaitForExit(10000);

            if (!p.HasExited)
            {
                p.Kill();
                Console.WriteLine("Killed!!!");
            }

            Console.WriteLine(p.StandardOutput.ReadToEnd());
            Console.WriteLine(p.StandardError.ReadToEnd());
            Console.ReadLine();
        }
    }

如何避免这种情况并使程序正常存在而不会使其超时失效？

问题是有人必须使用stdout缓冲区，否则它将被填充并且进程被卡住（参见解释here）。差异我正在尝试检索983行，这导致缓冲区溢出。

以下是我的问题的解决方案：

class Program
    {
        static void Main(string[] args)
        {
            ProcessStartInfo pInfo = new ProcessStartInfo();
            pInfo.FileName = "git.exe";
            pInfo.Arguments = "diff --name-only --exit-code V2.4-Beta-01 HEAD";
            pInfo.WorkingDirectory = @"C:\Git";
            pInfo.UseShellExecute = false;
            pInfo.CreateNoWindow = true;
            pInfo.RedirectStandardError = true;
            pInfo.RedirectStandardOutput = true;

            string output = string.Empty;

            Process p = new Process();
            p.StartInfo = pInfo;

            p.OutputDataReceived += new DataReceivedEventHandler((sender, e) =>
            {
                if (!String.IsNullOrEmpty(e.Data))
                {
                    output += e.Data + Environment.NewLine;
                }
            });

            p.Start();

            p.BeginOutputReadLine();

            p.WaitForExit();
            p.Close();

            Console.WriteLine(output);
            Console.ReadLine();
        }
    }

当作为.NET进程运行时，Git diff会卡住
