用ASCII字符画两个相邻的矩形

本文关键字：两个 字符 ASCII | 更新日期: 2023-09-27 17:54:00

我的目标是画两个相邻的矩形。我写了一个矩形的代码，但是我不能画两个相邻的矩形。我看到问题在哪里，但我不知道如何解决它。非常感谢你的帮助。

class DrawRectangles
{           
    static void Main(){
        Console.WriteLine(DrawRectangle(8,8)+DrawRectangle(4,3));
    }
    static string DrawRectangle(int width,int length){
        StringBuilder sb = new StringBuilder();
        string first = "+" + " -".StringMultiplier(width-1)+ " + ";
        sb.AppendLine(first);
        for(int i=0; i<length-1;i++)
            sb.AppendLine("|"+" ".StringMultiplier(2*width-1)+"|");
        sb.Append(first);
        return sb.ToString();
    }
}   
internal static class StringExtensions
{       
    public static string StringMultiplier(this string value,int count){
        StringBuilder sb = new StringBuilder(count);
        for(int i=0;i<count;i++)
            sb.Append(value);
        return sb.ToString();
    }       
}

预期输出: 

+ - - - - - - - +|               ||               ||               ||               |+ - - - +|               ||       ||               ||       ||               ||       |+ - - - - - - - ++ - - - +之前
电流输出: 
<>之前+ - - - - - - - +|               ||               ||               ||               ||               ||               ||               |+ - - - - - - - ++ - - - +|       ||       |+ - - - +

用ASCII字符画两个相邻的矩形

首先，StringMultiplier扩展是不必要的，因为您可以使用System.String(Char, Int32)来完成相同的事情。

下面是你真正需要的代码: 
// Assume the Tuples are <height, width>
string DrawRectangles(params Tuple<int, int>[] measurements)
{
    var sb = new StringBuilder();
    var maxHeight = measurements.Max(measurement => measurement.Item1);
    for (var h = maxHeight; h > 0; h--)
    {
        foreach (var measurement in measurements)
        {
            // If you're on the top or bottom row of a rectangle...
            if (h == 0 || measurement.Item1 == h)
            {
                sb.Append(String.Format("{0}{1}{0}", "+", new String('-', measurement.Item2 - 2)));
                continue;
            }
            // If you're in the middle of a rectangle...
            if (measurement.Item1 > h)
            {
                sb.Append(String.Format("{0}{1}{0}", "+", new String(' ', measurement.Item2 - 2)));
                continue;
            }
            sb.Append(new String(' ', measurement.Item2));
        }
        sb.Append(Environment.NewLine);
    }
    return sb.ToString();
}

用法:

var output = DrawRectangles(new Tuple(8, 8), new Tuple(4, 3), etc...);

代替此代码

string first = "+" + " -".StringMultiplier(width-1)+ " + ";

你可以简单地使用这个模式:

string first = string.Format("+{0}+", new string('-', width - 2));
