将文本数据从文件重定向到Stdin C#Windows [英] Redirecting text data from file to stdin c# windows

问题描述

如何将数据从某些文本文件重定向到C#程序的stdin?通过某些代码或命令提示符(在Windows中)?我曾尝试在命令提示符下将其重定向为:input.txt> program.exe> output.txt(例如在Linux中)，但这不起作用.也尝试过这种方式:

How can I redirect data from some text file to the C# program's stdin? Via some code or command prompt (in Windows)? I've tried redirecting it in command prompt like this: input.txt > program.exe > output.txt (like in linux), but that's not working. Also tried it this way:

string path = @"D:\input.txt";
// Open the file to read from. 
using (StreamReader sr = File.OpenText(path))
{
    string s = "";
    using (StreamWriter stdinput = new StreamWriter(Console.OpenStandardInput()))
    {
        while ((s = sr.ReadLine()) != null)
        {
            stdinput.WriteLine(s);
        }
    }
}

但这也不起作用.它因出现以下错误而崩溃:

But this didn't work either. It crushes with the following error:

发生了类型为'System.ArgumentException'的未处理异常 mscorlib.dll

"An unhandled exception of type 'System.ArgumentException' occurred in mscorlib.dll

其他信息:流不可写."

Additional information: Stream was not writable."

我该怎么办?

推荐答案

使用命令重定向运算符

 program.exe < input.txt > output.txt
