我需要在C#控制台应用程序中使用扩展ASCII绘制一个带有数字的矩形。我该如何做?
这是为了演示。

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();
}
}
╔ ═ ╗ ╚ ╝
- Alex K.║
。 - IC_string tmp = "some value"; Console.Write(tmp.DrawInConsoleBox());
public static string DrawInConsoleBox(this string s)
{
string ulCorner = "╔";
string llCorner = "╚";
string urCorner = "╗";
string lrCorner = "╝";
string vertical = "║";
string horizontal = "═";
string[] lines = s.Split(new char[] { '\r', '\n' }, StringSplitOptions.RemoveEmptyEntries);
int longest = 0;
foreach(string line in lines)
{
if (line.Length > longest)
longest = line.Length;
}
int width = longest + 2; // 1 space on each side
string h = string.Empty;
for (int i = 0; i < width; i++)
h += horizontal;
// box top
StringBuilder sb = new StringBuilder();
sb.AppendLine(ulCorner + h + urCorner);
// box contents
foreach (string line in lines)
{
double dblSpaces = (((double)width - (double)line.Length) / (double)2);
int iSpaces = Convert.ToInt32(dblSpaces);
if (dblSpaces > iSpaces) // not an even amount of chars
{
iSpaces += 1; // round up to next whole number
}
string beginSpacing = "";
string endSpacing = "";
for (int i = 0; i < iSpaces; i++)
{
beginSpacing += " ";
if (! (iSpaces > dblSpaces && i == iSpaces - 1)) // if there is an extra space somewhere, it should be in the beginning
{
endSpacing += " ";
}
}
// add the text line to the box
sb.AppendLine(vertical + beginSpacing + line + endSpacing + vertical);
}
// box bottom
sb.AppendLine(llCorner + h + lrCorner);
// the finished box
return sb.ToString();
}
想要显示类似这样的内容吗?
这对我有用:
Console.OutputEncoding = Encoding.GetEncoding(866);
Console.WriteLine("┌─┐");
Console.WriteLine("│1│");
Console.WriteLine("└─┘");

回答评论中的子问题:
Console.OutputEncoding = Encoding.GetEncoding(866);
Console.WriteLine(" ┌─┐");
Console.WriteLine(" │1│");
Console.WriteLine("┌─┼─┘");
Console.WriteLine("│1│");
Console.WriteLine("└─┘");
您可以使用CsConsoleFormat†在控制台中使用ASCII边框符号进行绘制。
使用“双”线在矩形内绘制数字:
ConsoleRenderer.RenderDocument(
new Document()
.AddChildren(
new Border {
Stroke = LineThickness.Wide,
Align = HorizontalAlignment.Left
}
.AddChildren(1337)
)
);
您可以更改 Stroke = LineThickness.Wide
行来更改线条的样式。 LineThickness.Single
会产生细单线,new LineThickness(LineWidth.Single, LineWidth.Wide)
会产生单竖线和双横线。
这是它的样子:
你也可以使用ConsoleBuffer
类来显式地绘制行(参数名称已添加以增加清晰度):
using static System.ConsoleColor;
var buffer = new ConsoleBuffer(width: 6);
buffer.DrawHorizontalLine(x: 0, y: 0, width: 6, color: White);
buffer.DrawHorizontalLine(x: 0, y: 2, width: 6, color: White);
buffer.DrawVerticalLine(x: 0, y: 0, height: 3, color: White);
buffer.DrawVerticalLine(x: 5, y: 0, height: 3, color: White);
buffer.DrawString(x: 1, y: 1, color: White, text: "1337");
new ConsoleRenderTarget().Render(buffer);
† CsConsoleFormat 是由我开发的。
public class AsciDrawing
{
public static void TestMain() {
var w = Console.WindowWidth;
var h = Console.WindowHeight;
RecursiveDraw(16, 8, new Point(w/2-8, h/2-4), ConsoleColor.Black);
Console.CursorTop = h;
Console.CursorLeft = 0;
}
public static void RecursiveDraw(int Width, int Height, Point Location, ConsoleColor BorderColor) {
if(Width < 4 || Height < 2) return;
Draw(Width, Height, Location, BorderColor); //Commnet this draw and and Uncomment Draw bellow to see the difference.
Thread.Sleep(500);
//Comment or Uncomment to see how many recursive calls you want to make
//The best is to comment all execpt 1 and then uncomment 1 by 1
RecursiveDraw(Width/2, Height/2, new Point(Location.X-Width/4, Location.Y-Height/4), ConsoleColor.Green); //Left Top
RecursiveDraw(Width / 2, Height / 2, new Point(Location.X + 3* Width / 4, Location.Y + 3* Height / 4), ConsoleColor.Red); //Right Bottom
RecursiveDraw(Width / 2, Height / 2, new Point(Location.X + 3* Width / 4, Location.Y - Height / 4), ConsoleColor.Blue); //Right Top
RecursiveDraw(Width / 2, Height / 2, new Point(Location.X - Width / 4, Location.Y + 3* Height / 4), ConsoleColor.DarkMagenta); // Left Bottom
//Draw(Width, Height, Location, BorderColor);
}
public static void Draw(int Width, int Height, Point Location, ConsoleColor BorderColor)
{
Console.ForegroundColor = BorderColor;
string s = "╔";
string temp = "";
for (int i = 0; i < Width; i++)
s += "═";
s += "╗" + "\n";
Console.CursorTop = Location.Y;
Console.CursorLeft = Location.X;
Console.Write(s);
for (int i = 0; i < Height; i++) {
Console.CursorTop = Location.Y + 1 + i;
Console.CursorLeft = Location.X;
Console.WriteLine("║");
Console.CursorTop = Location.Y + 1 + i;
Console.CursorLeft = Location.X + Width+1;
Console.WriteLine("║");
}
s = temp + "╚";
for (int i = 0; i < Width; i++)
s += "═";
s += "╝" + "\n";
Console.CursorTop = Location.Y+Height;
Console.CursorLeft = Location.X;
Console.Write(s);
Console.ResetColor();
}
}
public record Point(int X, int Y);
