看过this question并修改代码以打印“☺”、“☻”或“█”等字符,我看不出如何使用 WriteConsoleOutput 正确绘制这些字符。 (使用流或 Console.Write 时没有问题,但我无法使用这些解决方案单独控制字符颜色,因此它们不合适。)
似乎有一个解决方案here对于 C++,但他们在底部讨论的“L”宏不适用于 C#。
最后,查看了建议here ,我看不出我最终得到的代码有什么问题:
class Program
{
[DllImport("Kernel32.dll", SetLastError = true, CharSet = CharSet.Unicode)]
static extern SafeFileHandle CreateFile(
string fileName,
[MarshalAs(UnmanagedType.U4)] uint fileAccess,
[MarshalAs(UnmanagedType.U4)] uint fileShare,
IntPtr securityAttributes,
[MarshalAs(UnmanagedType.U4)] FileMode creationDisposition,
[MarshalAs(UnmanagedType.U4)] int flags,
IntPtr template
);
[DllImport("kernel32.dll", SetLastError = true)]
static extern bool WriteConsoleOutputW(
SafeFileHandle hConsoleOutput,
CharInfo[] lpBuffer,
Coord dwBufferSize,
Coord dwBufferCoord,
ref SmallRect lpWriteRegion
);
[DllImport("kernel32.dll", SetLastError = true)]
private static extern bool SetConsoleOutputCP(uint wCodePageID);
[DllImport("kernel32.dll", SetLastError = true)]
private static extern bool SetConsoleCP(uint wCodePageID);
[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.Explicit)]
public struct CharUnion
{
[FieldOffset(0)] public char UnicodeChar;
[FieldOffset(0)] public byte AsciiChar;
}
[StructLayout(LayoutKind.Explicit)]
public struct CharInfo
{
[FieldOffset(0)] public CharUnion Char;
[FieldOffset(2)] public short Attributes;
}
[StructLayout(LayoutKind.Sequential)]
public struct SmallRect
{
public short Left;
public short Top;
public short Right;
public short Bottom;
}
static void Main(string[] args)
{
//SetConsoleOutputCP(65001);
//SetConsoleCP(65001);
SafeFileHandle fileHandle = CreateFile("CONOUT$", 0x40000000, 2, IntPtr.Zero, FileMode.Open, 0, IntPtr.Zero);
Console.TreatControlCAsInput = true;
//Console.OutputEncoding = Encoding.UTF8;
Console.OutputEncoding = System.Text.Encoding.Unicode;
Console.CursorVisible = false;
short screenWidth = 40;
short screenHeight = 20;
Console.SetWindowSize(screenWidth + 1, screenHeight + 1);
Console.SetBufferSize(screenWidth + 1, screenHeight + 1);
bool running = true;
while (running)
{
CharInfo[] buf = new CharInfo[screenWidth * screenHeight];
SmallRect rect = new SmallRect() { Left = 0, Top = 0, Right = screenWidth, Bottom = screenHeight };
for (int i = 0; i < buf.Length; ++i)
{
buf[i].Attributes = 6;
buf[i].Char.UnicodeChar = '☺';
}
bool b = WriteConsoleOutputW(
fileHandle,
buf,
new Coord() { X = screenWidth, Y = screenHeight },
new Coord() { X = 0, Y = 0 },
ref rect
);
Console.SetCursorPosition(0, 0);
}
}
}
我似乎已经排除了CharSet、A/W DLLImport 后缀、code pages、Console的所有组合strong> 属性和源文件 编码。
(当然,将彩色笑脸字符快速打印到 C# 控制台并非不可能。有人告诉我我在这里漏掉了一些愚蠢的东西;我花了大约 2 个小时谷歌搜索并尝试轻松模拟 1984 年管理的 Castle Adventure。)
我怎样才能让前面提到的 '☺' 打印除 '?' 以外的任何内容?还是“:”?
