    MessageBoxIcon.Error);
   }
   }
  }
  }
 }
 public BitArray StrToBit(string id)//把字符串转换为bitArray
 {
  if (id.Length != 25)
  {
  throw new System.FormatException("砖块样式信息不合法！请删除BlockSet.xml文件，并重新启动程序");
  }
  BitArray ba = new BitArray(25);

  }

 }
 public void Add(BitArray id, Color bColor)//添加一个砖块信息
 {
  if (id.Length != 25)
  {
  throw new System.FormatException("砖块样式信息不合法！请删除blockset.xml文件，并重新启动程序");
  }
  info.Add(new BlockInfo(id, bColor));//给动态数组info添加一个砖块信息
  _length++;//长度加一
 }
 public void Add(string id, string bColor)
