C#console应用程序中的自定义文本颜色？

Tho*_*mas 31 c# console console-application textcolor visual-studio

我刚刚为项目完成了我的C#控制台应用程序代码,并希望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？

这是我过去用来改变颜色的代码,但它不提供橙色:

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

有没有办法可以为颜色或类似的东西插入十六进制值？

该列表位于http://msdn.microsoft.com/en-us/library/system.console.backgroundcolor.aspx

我相信是控制台中唯一支持的颜色.不允许十六进制.

~~但是在进一步调查中,你可以做很多工作,将红色和黄色结合起来变成橙色.按照这里的例子.不会重新发布代码墙. http://support.microsoft.com/kb/319883~~ 这不会让您访问更多颜色,但确实导致了正确的方向.你需要做一些PINVOKE工作,但我很容易将橙色或任何其他RGB颜色变成控制台. http://pinvoke.net/default.aspx/kernel32.SetConsoleScreenBufferInfoEx

然后,如果您想使用橙色或任何其他颜色,您可以简单地调用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.

.Net框架不为控制台前景色支持自定义RGB颜色，这很奇怪，因为它本身受支持。伟大的解决方案本杰明！ (2认同)

[无耻的自我推销]

我正在开发一个项目,允许您在任何System.Drawing.Color中设置控制台输出的样式,包括橙色.这是你如何做到的:

Console.WriteLine("writing to the console in orange", Color.Orange);

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

您需要通过SetConsoleMode设置标志ENABLE_VIRTUAL_TERMINAL_PROCESSING(0x4)
使用顺序:

"\ X1B [48; 5;" + s +"m" - 按表中的索引设置背景颜色(0-255)

"\ X1B [38; 5;" + s +"m" - 按表中的索引设置前景色(0-255)

"\ X1B [48; 2;" + r +";" + g +";"+ b +"m" - 用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

重要通知:内部Windows在表格中只有256(或88)种颜色,Windows将最接近表格中的(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();
        }
    }
