我需要解释此代码 [英] i need explain of this code please

问题描述

//宽度和高度的属性.

// Properties for Width and Height.

public double Width {
   get { return pri_width; }
   set { pri_width = value < 0 ? -value : value; }
}

推荐答案

这基本上只允许设置正宽度.任何负数都将转换为正数. Abs()函数也可以实现这一点.

这里的功能相同:

This basically only allows setting a positive Width. Any negative number is converted to positive. The Abs() function would also achieve that.

This here does the same:

public double Width
     {
        get { return pri_width; }
        set { pri_width = Math.Abs(value); }
     }

代码的简化版本

The simplified version of the code

public double Width 
{
     get 
     { 
          return pri_width; 
     }
     set 
     { 
          if(value < 0)
          {
                pri_width =  -value;
          }
          else
          {
                pri_width =  value;
          }
     }
  }

阅读三元运算符以取消原始代码.

如果您不了解属性:

Read ternary operator to unserstadn original code.

if you dont understand properties:

public double GetWidth
{
    
          return pri_width;
}

     public void setWidth(double value)
     {
          if(value < 0)
          {
                pri_width =  -value;
          }
          else
          {
                pri_width =  value;
          }
     }

免责声明:JF2015提供的解决方案是最好的.我只是在解释原始代码.
