C# 控制台应用程序中的自定义文本颜色？

Question

我刚刚完成了一个项目的 C# 控制台应用程序代码，并想为我的字体添加一些颜色。我希望能够使用自定义颜色 - 橙色。有没有办法做到这一点？

这是我过去用来更改颜色的代码，但它不提供橙色：

Console.ForegroundColor = ConsoleColor.Magenta(and so on);

有没有办法为颜色或类似的东西插入一个十六进制值？

Answer 1

在http://msdn.microsoft.com/en-us/library/system.console.backgroundcolor.aspx找到的列表

我相信是控制台中唯一支持的颜色。不允许使用十六进制。

Black
DarkBlue
DarkGreen
DarkCyan
DarkRed
DarkMagenta
DarkYellow
Gray
DarkGray
Blue
Green
Cyan
Red
Magenta
Yellow
White

从我的公共仓库中获取工作项目文件

但是在进一步的调查中，你可以做很多工作来结合红色和黄色来得到橙色。按照此处的示例进行操作。不会重新发布代码墙。 http://support.microsoft.com/kb/319883 这不会让您获得更多颜色，但会导致正确的方向。您将需要做一些 PINVOKE 工作，但我很容易将橙色或任何其他 RGB 颜色输入控制台。 http://pinvoke.net/default.aspx/kernel32.SetConsoleScreenBufferInfoEx

        irc = SetColor(ConsoleColor.Black, backgroundColor);
        if (irc != 0) return irc;

        return 0;
    }
}

如果你想使用橙色或任何其他颜色，你可以简单地调用 SetScreenColor

static void Main(string[] args)
    {

        Color screenTextColor = Color.Orange;
        Color screenBackgroundColor = Color.Black;
        int irc = SetScreenColorsApp.SetScreenColors(screenTextColor, screenBackgroundColor);
        Debug.Assert(irc == 0, "SetScreenColors failed, Win32Error code = " + irc + " = 0x" + irc.ToString("x"));

        Debug.WriteLine("LargestWindowHeight=" + Console.LargestWindowHeight + " LargestWindowWidth=" + Console.LargestWindowWidth);
        Debug.WriteLine("BufferHeight=" + Console.BufferHeight + " WindowHeight=" + Console.WindowHeight + " BufferWidth=" + Console.BufferWidth + " WindowWidth=" + Console.WindowWidth);
        //// these are relative to the buffer, not the screen:
        //Debug.WriteLine("WindowTop=" + Console.WindowTop + " WindowLeft=" + Console.WindowLeft);
        Debug.WriteLine("ForegroundColor=" + Console.ForegroundColor + " BackgroundColor=" + Console.BackgroundColor);
        Console.WriteLine("Some text in a console window");
        Console.BackgroundColor = ConsoleColor.Cyan;
        Console.ForegroundColor = ConsoleColor.Yellow;
        Debug.WriteLine("ForegroundColor=" + Console.ForegroundColor + " BackgroundColor=" + Console.BackgroundColor);
        Console.Write("Press ENTER to exit...");
        Console.ReadLine();

        // Note: If you use SetScreenColors, the RGB values of gray and black are changed permanently for the console window.
        // Using i.e. Console.ForegroundColor = ConsoleColor.Gray afterwards will switch the color to whatever you changed gray to

        // It's best to use SetColor for the purpose of choosing the 16 colors you want the console to be able to display, then use
        // Console.BackgroundColor and Console.ForegrondColor to choose among them.
    }

自 Windows 10 周年更新以来，控制台可以使用 ANSI/VT100 颜色代码

1. 您需要通过 SetConsoleMode 设置标志 ENABLE_VIRTUAL_TERMINAL_PROCESSING(0x4)

2. 使用序列：

   "\x1b[48;5;" + s + "m" - 通过表中的索引设置背景颜色 (0-255)

   "\x1b[38;5;" + s + "m" - 通过表中的索引（0-255）设置前景色

   "\x1b[48;2;" + r + ";" + g + ";" + b + "m" - 通过 r,g,b 值设置背景

   "\x1b[38;2;" + r + ";" + g + ";" + b + "m" - 通过 r,g,b 值设置前景

重要提示：Windows 内部在表格中只有 256 种（或 88 种）颜色，Windows 将使用最接近表格中的 (r,g,b) 值。

示例代码：

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Runtime.InteropServices;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApp1
{
    class Program
    {
        [DllImport( "kernel32.dll", SetLastError = true )]
        public static extern bool SetConsoleMode( IntPtr hConsoleHandle, int mode );
        [DllImport( "kernel32.dll", SetLastError = true )]
        public static extern bool GetConsoleMode( IntPtr handle, out int mode );

        [DllImport( "kernel32.dll", SetLastError = true )]
        public static extern IntPtr GetStdHandle( int handle );

        static void Main( string[] args )
        {
            var handle = GetStdHandle( -11 );
            int mode;
            GetConsoleMode( handle, out mode );
            SetConsoleMode( handle, mode | 0x4 );

            for (int i=0;i<255;i++ )
            {
                Console.Write( "\x1b[48;5;" + i + "m*" );
            }

            Console.ReadLine();
        }
    }
}

在这里扩展 Alexei Shcherbakov Windows 10 ENABLE_VIRTUAL_TERMINAL_PROCESSING 的答案是一个完整的颜色代码映射，因此您可以将所有颜色及其各自的数字放在一个地方：

Answer 4

迟到总比没有好，但现在看来这是可能的，至少在 Vista 和更高版本上是这样。因此，我将添加此内容以供有相同问题的其他人将来参考。

当我打算这样做时，我遇到了 Hans Passant 的reply on MSDN：

我现在无法访问 Vista，所以无法尝试。但是有些东西 这样应该可以工作：

CONSOLE_SCREEN_BUFFER_INFOEX info;
info.cbSize = sizeof(info);
HANDLE hConsole = GetStdHandle(STD_OUTPUT_HANDLE);
GetConsoleScreenBufferInfoEx(hConsole, &info);
info.ColorTable[14] = RGB(255, 128, 0);  // Replace yellow
SetConsoleScreenBufferInfoEx(hConsole, &info);
SetConsoleTextAttribute(hConsole, FOREGROUNDINTENSITY | FOREGROUND_RED | FOREGROUND_GREEN);

这需要一点 p-Invoking，但应该会给你一些东西。

Answer 5

您可以使用Colorful.Console，它可以让您使用自定义颜色，甚至可以使用 Figlet 字体来制作 ASCII 艺术！

Answer 6

它不是橙色，因为该颜色不是控制台支持的颜色之一。我的意思是，即使使用 Windows API，您也无法获得它。如果您想验证它，请查看以下代码：

   public static class Win32
    {
        [DllImport("kernel32.dll", SetLastError = true)]
        public static extern bool SetConsoleTextAttribute(IntPtr hConsoleOutput, short attributes);

        [DllImport("kernel32.dll", SetLastError = true)]
        public static extern IntPtr GetStdHandle(int nStdHandle);
    }

    public class Program
    {
        static void Main(string[] args)
        {
            foreach(var i in Enumerable.Range(0, 100)) // why "100"? it is just any number
            {
                Win32.SetConsoleTextAttribute(Win32.GetStdHandle(-11), (short)i);
                Console.WriteLine("Hello");
            }
        }
    }

进一步证明这不起作用（使用本杰明链接中的方法）：

using System.Runtime.InteropServices;

namespace
{
    class Program
    {
        [DllImport("kernel32.dll")]
        public static extern bool SetConsoleTextAttribute(IntPtr hConsoleOutput, int wAttributes);
        [DllImport("kernel32.dll")]
        public static extern IntPtr GetStdHandle(uint nStdHandle);

        static void Main(string[] args)
        {
            uint STD_OUTPUT_HANDLE = 0xfffffff5;
            IntPtr hConsole = GetStdHandle(STD_OUTPUT_HANDLE);

            SetConsoleTextAttribute(hConsole, (int)Colour.Red + (int)Colour.Green + (int)Colour.Intensity);
            Console.WriteLine("Red + Green + Intensity == Yellow");

            SetConsoleTextAttribute(hConsole, (int)Colour.Red + (int)Colour.Green + (int)Colour.Intensity + (int)Colour.Red);
            Console.WriteLine("Yellow + Red != Orange");

            SetConsoleTextAttribute(hConsole, 15);
            Console.WriteLine();
            Console.WriteLine("Press Enter to exit ...");
            Console.Read();
        }

        public enum Colour
        {
            Blue = 0x00000001,
            Green = 0x00000002,
            Red = 0x00000004,
            Intensity = 0x00000008
        }
    }
}

此方法不允许您添加任何无法通过 ConsoleColor 访问的内容。真的很遗憾，因为我也很想在我的应用程序中添加橙色。如果有人找到了我会非常感兴趣的方法。

Answer 8

有点晚了，我知道。但是，实现 C# 控制台中通常不可用的颜色的一种方法是更改​​注册表中颜色的 ColorCode。但请注意，这可能是最不可接受的方式。 只需打开regedit（Win + R，然后键入“regedit”），转到HKEY_CURRENT_USER，打开“Console”键（此时您应该导出“Console”键以便稍后恢复它）。在那里，您将看到从 ColorTable00 到 ColoTable15 的值列表。如果您将 ColorTable10 从 0x0000ff00 更改为 0x0000a5ff（或 65280 至 42495），则在重新启动后在控制台中使用 ConsoleColor.Green 时，您将看到橙色。也可以通过代码改变这个值

using System;
using Microsoft.Win32;

namespace colorChanger
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.ForegroundColor = ConsoleColor.Green;
            Console.WriteLine("Hello World");
            RegistryKey regKey = Registry.CurrentUser.CreateSubKey("Console");
            regKey.SetValue("ColorTable10", 42495, RegistryValueKind.DWord);
            Console.ReadKey();
        }
    }
}

当然，这适用于所有其他 ColorTable-Values 和 Colorcodes，但它仅针对您 PC 上的用户进行更改。
