“StandardOut 尚未重定向或进程尚未启动"在 C# 中读取控制台命令输出时 [英] "StandardOut has not been redirected or the process hasn't started yet" when reading console command output in C#

问题描述

感谢@user2526830 提供代码.基于该代码，我在程序中添加了几行，因为我想读取 SSH 命令的输出.下面是我的代码，它在 while

Thanks to @user2526830 for the code. Based on that code I added few lines to my program since I want to read the output of the SSH command. Below is my code which gives an error at line while

StandardOut 尚未重定向或进程尚未启动.

StandardOut has not been redirected or the process hasn't started yet.

我想实现的是我想把ls的输出读成一个字符串.

What I want to achieve is that I want to read the output of ls into a string.

ProcessStartInfo startinfo = new ProcessStartInfo();
startinfo.FileName = @"f:\plink.exe";
startinfo.Arguments = "-ssh abc@x.x.x.x -pw abc123";
Process process = new Process();
process.StartInfo = startinfo;
process.StartInfo.UseShellExecute = false;
process.StartInfo.RedirectStandardInput = true;
process.Start();
process.StandardInput.WriteLine("ls -ltr /opt/*.tmp");
process.StandardInput.WriteLine("exit");

process.StartInfo.RedirectStandardOutput = true;

while (!process.StandardOutput.EndOfStream)
{
    string line = process.StandardOutput.ReadLine();
}

process.WaitForExit();
Console.ReadKey();

推荐答案

在开始进程之前尝试设置标准输出重定向.

Try setting standard output redirection before starting the process.

process.StartInfo.RedirectStandardOutput = true;
process.Start();
