[英]How to draw a rectangle in console application?
我需要在C#控制台應用程序中使用擴展的ASCII繪制一個內部帶有數字的矩形。 我該怎么辦呢?
這是一個演示。
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();
}
}
喜歡這個 ?
這對我有用:
Console.OutputEncoding = Encoding.GetEncoding(866);
Console.WriteLine("┌─┐");
Console.WriteLine("│1│");
Console.WriteLine("└─┘");
[編輯]
回答評論中的子問題:
Console.OutputEncoding = Encoding.GetEncoding(866);
Console.WriteLine(" ┌─┐");
Console.WriteLine(" │1│");
Console.WriteLine("┌─┼─┘");
Console.WriteLine("│1│");
Console.WriteLine("└─┘");
這是String的擴展方法,它將在給定字符串周圍繪制一個控制台框。 包括多線支持。
即string tmp = "some value"; Console.Write(tmp.DrawInConsoleBox());
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();
}
您可以使用CsConsoleFormat †在控制台中使用ASCII邊框符號進行繪制。
使用“雙”線在矩形內繪制數字:
ConsoleRenderer.RenderDocument(
new Document()
.AddChildren(
new Border {
Stroke = LineThickness.Wide,
Align = HorizontalAlignment.Left
}
.AddChildren(1337)
)
);
您可以更改Stroke = LineThickness.Wide
行以更改線條樣式。 LineThickness.Single
會產生細線, new LineThickness(LineWidth.Single, LineWidth.Wide)
將產生單個垂直和雙水平線。
這是它的樣子:
您還可以使用ConsoleBuffer
類顯式繪制線條(為清晰起見,添加了參數名稱):
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是我開發的。
