.NET中的高级控制台IO

console.setcursorposition、console.backgroundcolor、console.foregroundcolor和console.resetcolor。

注意:这些是在2.0版中添加到.NET框架中的。在那之前,你需要松果。

根据 Mono Library List 至少有两个库对您有用:

• Curses# 在Windows上使用pdcurse,在Linux上使用ncurse。它几乎是二进制级的跨平台。

• MonoCurses 是一个MIT-X11许可的Curses绑定,它包括用于创建基于控制台的应用程序的最简单的gui.cs gui工具包。

This posting 演示如何使用控制台类方法在控制台上创建进度条-这可能是一个很好的例子,可以参考….

最有效的功能是 WriteConsoleOutput . 它是本机Win32 API,但可以在.NET应用程序中使用p/invoke:

[DllImport("kernel32.dll", SetLastError = true, EntryPoint = "WriteConsoleOutputW")]
public static extern bool WriteConsoleOutput(IntPtr hConsoleOutput, CHAR_INFO[,] lpBuffer, COORD dwBufferSize,
                                                 COORD dwBufferCoord, ref SMALL_RECT lpWriteRegion);

其中char_info是一个结构:

/// <summary>
/// CharSet.Unicode is required for proper marshaling.
/// </summary>
[StructLayout(LayoutKind.Explicit, CharSet = CharSet.Unicode)]
public struct CHAR_INFO
{
    [FieldOffset(0)]
    public char UnicodeChar;
    [FieldOffset(0)]
    public char AsciiChar;
    [FieldOffset(2)] //2 bytes seems to work properly
    public Attr Attributes;

    public override string ToString() {
        return string.Format("CHAR_INFO : '{0}' ({1})", AsciiChar, Attributes);
    }
}

AtTR结构:

/// <summary>
/// CHAR_ATTRIBUTES native structure.
/// </summary>
[Flags]
public enum Attr : ushort {
    NO_ATTRIBUTES = 0x0000,
    /// <summary>
    /// Text color contains blue.
    /// </summary>
    FOREGROUND_BLUE = 0x0001,
    /// <summary>
    /// Text color contains green.
    /// </summary>
    FOREGROUND_GREEN = 0x0002,
    /// <summary>
    /// Text color contains red.
    /// </summary>
    FOREGROUND_RED = 0x0004,
    /// <summary>
    /// Text color is intensified.
    /// </summary>
    FOREGROUND_INTENSITY = 0x0008,
    /// <summary>
    /// Background color contains blue.
    /// </summary>
    BACKGROUND_BLUE = 0x0010,
    /// <summary>
    /// Background color contains green.
    /// </summary>
    BACKGROUND_GREEN = 0x0020,
    /// <summary>
    /// Background color contains red.
    /// </summary>
    BACKGROUND_RED = 0x0040,
    /// <summary>
    /// Background color is intensified.
    /// </summary>
    BACKGROUND_INTENSITY = 0x0080,
    /// <summary>
    /// Leading byte.
    /// </summary>
    COMMON_LVB_LEADING_BYTE = 0x0100,
    /// <summary>
    /// Trailing byte.
    /// </summary>
    COMMON_LVB_TRAILING_BYTE = 0x0200,
    /// <summary>
    /// Top horizontal
    /// </summary>
    COMMON_LVB_GRID_HORIZONTAL = 0x0400,
    /// <summary>
    /// Left vertical.
    /// </summary>
    COMMON_LVB_GRID_LVERTICAL = 0x0800,
    /// <summary>
    /// Right vertical.
    /// </summary>
    COMMON_LVB_GRID_RVERTICAL = 0x1000,
    /// <summary>
    /// Reverse foreground and background attribute.
    /// </summary>
    COMMON_LVB_REVERSE_VIDEO = 0x4000,
    /// <summary>
    /// Underscore.
    /// </summary>
    COMMON_LVB_UNDERSCORE = 0x8000
}

坐标和小矩形:

[StructLayout(LayoutKind.Sequential)]
public struct COORD
{
    public short X;
    public short Y;

    public COORD(short X, short Y)
    {
        this.X = X;
        this.Y = Y;
    }
};

[StructLayout(LayoutKind.Sequential)]
public struct SMALL_RECT
{
    public short Left;
    public short Top;
    public short Right;
    public short Bottom;

    public SMALL_RECT(short left, short top, short right, short bottom) {
        Left = left;
        Top = top;
        Right = right;
        Bottom = bottom;
    }
}
