如何在控制台应用程序中绘制矩形？

Question

我需要在C#控制台应用程序中使用扩展的ASCII绘制一个内部带有数字的矩形.我该怎么办呢？

这是一个演示.

Answer 1

public class ConsoleRectangle
{
    private int hWidth;
    private int hHeight;
    private Point hLocation;
    private ConsoleColor hBorderColor;

    public ConsoleRectangle(int width, int height, Point location, ConsoleColor borderColor)
    {
        hWidth = width;
        hHeight = height;
        hLocation = location;
        hBorderColor = borderColor;
    }

    public Point Location
    {
        get { return hLocation; }
        set { hLocation = value; }
    }

    public int Width
    {
        get { return hWidth; }
        set { hWidth = value; }
    }

    public int Height
    {
        get { return hHeight; }
        set { hHeight = value; }
    }

    public ConsoleColor BorderColor
    {
        get { return hBorderColor; }
        set { hBorderColor = value; }
    }

    public void Draw()
    {
        string s = "?";
        string space = "";
        string temp = "";
        for (int i = 0; i < Width; i++)
        {
            space += " ";
            s += "?";
        }

        for (int j = 0; j < Location.X ; j++)
            temp += " ";

        s += "?" + "\n";

        for (int i = 0; i < Height; i++)
            s += temp + "?" + space + "?" + "\n";

        s += temp + "?";
        for (int i = 0; i < Width; i++)
            s += "?";

        s += "?" + "\n";

        Console.ForegroundColor = BorderColor;
        Console.CursorTop = hLocation.Y;
        Console.CursorLeft = hLocation.X;
        Console.Write(s);
        Console.ResetColor();
    }
}

这是 String 的扩展方法，它将在给定字符串周围绘制一个控制台框。包括多行支持。

即\nstring tmp = "some value"; Console.Write(tmp.DrawInConsoleBox());

\n

        public static string DrawInConsoleBox(this string s)\n        {\n            string ulCorner = "\xe2\x95\x94";\n            string llCorner = "\xe2\x95\x9a";\n            string urCorner = "\xe2\x95\x97";\n            string lrCorner = "\xe2\x95\x9d";\n            string vertical = "\xe2\x95\x91";\n            string horizontal = "\xe2\x95\x90";\n\n            string[] lines = s.Split(new char[] { \'\\r\', \'\\n\' }, StringSplitOptions.RemoveEmptyEntries);\n            \n\n            int longest = 0;\n            foreach(string line in lines)\n            {\n                if (line.Length > longest)\n                    longest = line.Length;\n            }\n            int width = longest + 2; // 1 space on each side\n\n            \n            string h = string.Empty;\n            for (int i = 0; i < width; i++)\n                h += horizontal;\n\n            // box top\n            StringBuilder sb = new StringBuilder();\n            sb.AppendLine(ulCorner + h + urCorner);\n\n            // box contents\n            foreach (string line in lines)\n            {\n                double dblSpaces = (((double)width - (double)line.Length) / (double)2);\n                int iSpaces = Convert.ToInt32(dblSpaces);\n\n                if (dblSpaces > iSpaces) // not an even amount of chars\n                {\n                    iSpaces += 1; // round up to next whole number\n                }\n\n                string beginSpacing = "";\n                string endSpacing = "";\n                for (int i = 0; i < iSpaces; i++)\n                {\n                    beginSpacing += " ";\n\n                    if (! (iSpaces > dblSpaces && i == iSpaces - 1)) // if there is an extra space somewhere, it should be in the beginning\n                    {\n                        endSpacing += " ";\n                    }\n                }\n                // add the text line to the box\n                sb.AppendLine(vertical + beginSpacing + line + endSpacing + vertical);\n            }\n\n            // box bottom\n            sb.AppendLine(llCorner + h + lrCorner);\n\n            // the finished box\n            return sb.ToString();\n        }\n

\n

输出如下\n
