“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

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.

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 [email protected] -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();
