为什么我的字符串右侧没有填充？

2023-05-26 admin

我正在尝试创建一个构建金字塔的程序。金字塔以数组的形式出现，每一层都是由星号组成的，然而，当我试图用填充居中每一层时，我只在每根字符串的左侧接收到填充。为什么会发生这种情况？

public class Kata
{
  public static string[] TowerBuilder(int nFloors)
  {
    string[] tower = new string[nFloors];
    
    for( int floorNum = 0; floorNum < nFloors; floorNum++ ) {
      int numOfStars = 2 * (floorNum + 1) - 1;
      int maxStars = 2 * nFloors - 1;
      
      char star = '*';  
      string floor = new string( star, numOfStars );
  
      int totalPadding = maxStars - floorNum - 1;
      int padding = totalPadding / 2;
      string centeredFloor = floor.PadLeft(padding).PadRight(padding);

      tower[floorNum] = centeredFloor;
    } 
  
    return tower;
  }
}
