简介： 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.

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：

=================================================================================

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：

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,
                        CallingConvention = CallingConvention.StdCall)]
private static extern int GetStdHandle(int nStdHandle);

        [DllImport("kernel32.dll", EntryPoint = "GetConsoleScreenBufferInfo",
                        SetLastError = true, CharSet = CharSet.Auto,
                        CallingConvention = CallingConvention.StdCall)]
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,
            Green = 0x00000002,
            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();
