C# 以编程方式使用docker并捕获standardoutput

我希望在进程内以编程方式运行一些docker命令，并捕获docker的标准输出。这些命令确实可以正常运行，但我无法捕获标准输出。例如，考虑下面的代码。我想读取docker info命令，但得到的只是一个空字符串。你知道有没有一种方法可以通过这种方式与docker互动吗？谢谢

    private static void VerifyDocker()
    {
        var processStartInfo = new ProcessStartInfo();
        var messagesBuilder = new StringBuilder();
        var arguments = "info --format '{{json .}}'";

        using (var process = new Process())
        {
            processStartInfo.FileName = "docker";
            processStartInfo.Arguments = arguments;
            processStartInfo.CreateNoWindow = true;
            processStartInfo.UseShellExecute = false;
            processStartInfo.RedirectStandardOutput = true;

            process.OutputDataReceived += (sender, e) => messagesBuilder.Append(e.Data);
            process.StartInfo = processStartInfo;

            process.Start();
            process.BeginOutputReadLine();
            process.WaitForExit();
            process.CancelOutputRead();

            var message = messagesBuilder.ToString();
        }
    }

是的，最好同时捕获这两个参数，并对传递到--format的参数使用双引号而不是单引号

docker是写给stdout还是stderr？您还应该捕获stderr（

processStartInfoRedirectStandardError

和

process.ErrorDataReceived

）这会保留输出着色的控制字符吗？

    private static void VerifyDocker()
    {
        var processStartInfo = new ProcessStartInfo();
        var messagesBuilder = new StringBuilder();
        var errorMessagesBuilder = new StringBuilder();
        var arguments = "info --format \"{{json .}}\"";

        using (var process = new Process())
        {
            processStartInfo.FileName = "docker";
            processStartInfo.Arguments = arguments;
            processStartInfo.CreateNoWindow = true;
            processStartInfo.UseShellExecute = false;
            processStartInfo.RedirectStandardOutput = true;
            processStartInfo.RedirectStandardError = true;

            process.OutputDataReceived += (sender, e) => messagesBuilder.Append(e.Data);
            process.ErrorDataReceived += (sender, e) => errorMessagesBuilder.Append(e.Data);
            process.StartInfo = processStartInfo;

            process.Start();
            process.BeginOutputReadLine();
            process.BeginErrorReadLine();
            process.WaitForExit();
            process.CancelOutputRead();
            process.CancelErrorRead();

            var message = messagesBuilder.ToString();
            var errrors = errorMessagesBuilder.ToString();
        }
    }
