如何在异步过程中从shell中检索完整的结果？

Question

请参阅这些帖子：此处1 和 < a href="https://stackoverflow.com/questions/2864078/how-avoids-deadlock-condition">here2 最后我通过构建异步解决方案解决了我的问题，并且效果很好！但是我面临一个问题，现在我的代码是这样的：

class MyProcessStarter
    {
        private Process process;
        private StreamWriter myStreamWriter;
        private static StringBuilder shellOutput = null;
        public String GetShellOutput { get { return shellOutput.ToString(); }}

        public MyProcessStarter(){
            shellOutput = new StringBuilder("");
            process = new Process();            
            process.StartInfo.FileName = "sqlplus";
            process.StartInfo.UseShellExecute = false;
            process.StartInfo.CreateNoWindow = true;
            process.OutputDataReceived += new DataReceivedEventHandler(ShellOutputHandler);

            process.StartInfo.RedirectStandardInput = true;
            process.StartInfo.RedirectStandardOutput = true;
            //process.StartInfo.RedirectStandardError = true;
            process.Start();
            myStreamWriter = process.StandardInput;
            process.BeginOutputReadLine();
        }

        private static void ShellOutputHandler(object sendingProcess,DataReceivedEventArgs outLine)
        {
            if (!String.IsNullOrEmpty(outLine.Data))
                shellOutput.Append(Environment.NewLine + outLine.Data);
        }

        public void closeConnection()
        {
            myStreamWriter.Close();
            process.WaitForExit();
            process.Close(); 
        }

        public void RunCommand(string arguments)
        {
            myStreamWriter.WriteLine(arguments);
            myStreamWriter.Flush();
            process.WaitForExit(100);
            Console.WriteLine(shellOutput);
            Console.WriteLine("============="+Environment.NewLine);
            process.WaitForExit(2000);
            Console.WriteLine(shellOutput);            
        }
    } 

我的输入是这样的：

 myProcesStarter.RunCommand("myusername/mypassword");
 Console.writeline(myProcesStarter.GetShellOutput);

但是看看我的输出：

正如你所看到的，运行函数的输出在不同时间是不一样的！那么现在你会帮我一个忙并帮助我，我如何才能等到所有输出以其他方式完成意味着我如何自定义我的流程以等到输出完成？因为我想写一个sqlcompiler所以我需要shell的精确输出。

请尽快帮助我。thanxxxxxxxxxxxx :X

Answer 1

您应该在 SQL*Plus 上使用 -S 参数。根据帮助，这个参数

设置静音模式以抑制
显示 SQL*Plus 横幅，
提示和命令回显。

理想情况下，这将使输出一致。
