C# 콘솔 애플리케이션에서 입력 리디렉션을 어떻게 감지할 수 있습니까?

<code class="language-csharp">using System;
using System.Runtime.InteropServices;

public static class ConsoleEx
{
    public static bool IsOutputRedirected => FileType.Char != GetFileType(GetStdHandle(StdHandle.Stdout));
    public static bool IsInputRedirected => FileType.Char != GetFileType(GetStdHandle(StdHandle.Stdin));
    public static bool IsErrorRedirected => FileType.Char != GetFileType(GetStdHandle(StdHandle.Stderr));

    // P/Invoke declarations:
    private enum FileType { Unknown, Disk, Char, Pipe };
    private enum StdHandle { Stdin = -10, Stdout = -11, Stderr = -12 };
    [DllImport("kernel32.dll")]
    private static extern FileType GetFileType(IntPtr hdl);
    [DllImport("kernel32.dll")]
    private static extern IntPtr GetStdHandle(StdHandle std);
}</code>

<code class="language-csharp">bool isInputRedirected = ConsoleEx.IsInputRedirected;</code>

<code class="language-csharp">bool isInputRedirected = Console.IsInputRedirected;</code>
