首先感謝院子里的“yanxinchen”，之前的方法是通過c#調用系統api實現的，相比之下我的有點畫蛇添足了，哈哈。

最佳解決方案的代碼：

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();
}

效果如圖：

我之前的代碼如下（已過時）：

控制臺應用程序字體本身不能輸出帶顏色的字體，所有就需要調用系統的api實現，下面是一個封裝好的類，另賦調用的方法，使用起來很方便，效果如圖：

封裝調用系統api的類ConsoleColor.cs代碼如下：

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方法的調用代碼如下：

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();
