有没有办法让一个对象的变量设置为另一个变量？

Question

有没有办法让对象变量的另一个变量？

比如我想在的位置 'TutGrass'

总是被设置为CharacterX和CharacterY

所以每当CharacterX和CharacterY的值更改位置的TutGrass将改变。

Answer 1

你可以使用属性来改变位置的值：

public int CharacterX 
{ 
    get 
    { 
    return Location.X; 
    } 
    set 
    { 
    Location = new Point(value, Location.Y); 
    } 
} 

这样的定位和字符的值绑在一起（Location.X将持有本例中的值）。如果你需要你可以有另一个中间变量保存值。通常它会是private。

在你的代码可以修改Location.X或CharacterX，他们都将被更新：

Location.X = 5; //Sets the value of Location.X to 5 
int testValue = CharacterX; //since CharacterX will return the value of Location.X testValue is assigned 5 

CharacterX = 6;//Sets the value of Location.X to 6. CharacterX never really holds a value, just assigns it to Location.X
