我的目标是绘制两个彼此相邻的矩形。我编写了绘制矩形的代码,但无法绘制两个相邻的矩形。我知道问题出在哪里,但我不知道如何解决它。非常感谢您的帮助。
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:
+ - - - - - - - + | | | | | | | |+ - - - + | || | | || | | || | + - - - - - - - ++ - - - +
当前输出:
+ - - - - - - - + | | | | | | | | | | | | | | + - - - - - - - ++ - - - + | | | | + - - - +
最佳答案
首先,StringMultiplier
扩展是不必要的,因为您可以使用 System.String(Char, Int32)
完成同样的事情。
这是您实际需要的代码:
// 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...);
