C# 控制台应用程序输出颜色字体[更正版]

首先感谢院子里的“yanxinchen”，之前的方法是通过c\#调用系统api实现的，相比之下我的有点画蛇添足了，哈哈。

最佳解决方案的代码：

static void Main(string[] args)
    {
       
        Console.ForegroundColor = ConsoleColor.Green;
        Console.WriteLine("Hello, color text!");
        Console.ForegroundColor = ConsoleColor.Red;
        Console.WriteLine("Hello, color text!");
        Console.ReadKey();
    }

效果如图：![2011092808461044.png][]

我之前的代码如下（已过时）：

控制台应用程序字体本身不能输出带颜色的字体，所有就需要调用系统的api实现，下面是一个封装好的类，另赋调用的方法，使用起来很方便，效果如图：

封装调用系统api的类ConsoleColor.cs代码如下：

![ContractedBlock.gif][] ![ExpandedBlockStart.gif][] ConsoleColor.cs

using System.Runtime.InteropServices;
    
    namespace Test
    {
        
        /// Summary description for ConsoleColor.
        public class ConsoleColor
        {
        
            private int hConsoleHandle;
            private COORD ConsoleOutputLocation;
            private CONSOLE_SCREEN_BUFFER_INFO ConsoleInfo;
            private int OriginalColors;
    
            private const int STD_OUTPUT_HANDLE = -11;
    
            [DllImport("kernel32.dll", EntryPoint = "GetStdHandle", SetLastError = true,
                            CharSet = CharSet.Auto,

            private static extern int GetConsoleScreenBufferInfo(int hConsoleOutput,
                             ref CONSOLE_SCREEN_BUFFER_INFO lpConsoleScreenBufferInfo);
    
            [DllImport("kernel32.dll", EntryPoint = "SetConsoleTextAttribute",
                            SetLastError = true, CharSet = CharSet.Auto,
                            CallingConvention = CallingConvention.StdCall)]
            private static extern int SetConsoleTextAttribute(int hConsoleOutput,
                                     int wAttributes);
    
            public enum Foreground
            {
        
                Blue = 0x00000001,

                Red = 0x00000004,
                Intensity = 0x00000008
            }
    
            public enum Background
            {
        
                Blue = 0x00000010,
                Green = 0x00000020,
                Red = 0x00000040,
                Intensity = 0x00000080
            }
    
            [StructLayout(LayoutKind.Sequential)]
            private struct COORD
            {
        
                short X;
                short Y;
            }
    
            [StructLayout(LayoutKind.Sequential)]
            private struct SMALL_RECT
            {
        
                short Left;
                short Top;
                short Right;
                short Bottom;
            }
    
            [StructLayout(LayoutKind.Sequential)]
            private struct CONSOLE_SCREEN_BUFFER_INFO
            {
        
                public COORD dwSize;
                public COORD dwCursorPosition;
                public int wAttributes;
                public SMALL_RECT srWindow;
                public COORD dwMaximumWindowSize;
            }
    
            // Constructor.
            public ConsoleColor()
            {
        
                ConsoleInfo = new CONSOLE_SCREEN_BUFFER_INFO();
                ConsoleOutputLocation = new COORD();
                hConsoleHandle = GetStdHandle(STD_OUTPUT_HANDLE);
                GetConsoleScreenBufferInfo(hConsoleHandle, ref ConsoleInfo);
                OriginalColors = ConsoleInfo.wAttributes;
            }
    
            public void TextColor(int color)
            {
        
                SetConsoleTextAttribute(hConsoleHandle, color);
            }
    
            public void ResetColor()
            {
        
                SetConsoleTextAttribute(hConsoleHandle, OriginalColors);
            }
        }
    }

在Main方法的调用代码如下：

ConsoleColor TextChange = new ConsoleColor();
    Console.WriteLine("Original Colors");
    Console.WriteLine("Press Enter to Begin");
    Console.ReadLine();
    TextChange.TextColor((int)ConsoleColor.Foreground.Green +
                         (int)ConsoleColor.Foreground.Intensity);
    Console.WriteLine("THIS TEXT IS GREEN");
    Console.WriteLine("Press Enter to change colors again");
    Console.ReadLine();
    TextChange.TextColor((int)ConsoleColor.Foreground.Red +
                         (int)ConsoleColor.Foreground.Blue +
                         (int)ConsoleColor.Foreground.Intensity);
    Console.WriteLine("NOW THE TEXT IS PURPLE");
    Console.WriteLine("Press Enter to change colors again");
    Console.ReadLine();
    TextChange.TextColor((int)ConsoleColor.Foreground.Blue +
                         (int)ConsoleColor.Foreground.Intensity +
                         (int)ConsoleColor.Background.Green +
                         (int)ConsoleColor.Background.Intensity);
    Console.WriteLine("NOW THE TEXT IS BLUE AND BACKGROUND OF IT IS GREEN");
    Console.WriteLine("Press Enter change everything back to normal");
    Console.ReadLine();
    TextChange.ResetColor();
    Console.WriteLine("Back to Original Colors");
    Console.WriteLine("Press Enter to Terminate");
    Console.ReadLine();
