C#WPF代码再大一点.............. [英] C# WPF code greater then.............

问题描述

这是我的代码

this is my code

if (view.Margin == new Thickness(view.Margin.Top > 0, -1, 0, 0))
        {
          //code in here
        }

可以请一个人解释为什么这行不通吗，请告诉我另一个我可以做到这一点?

我收到这些错误

can some one please explain why this isn''t working and please tell me another that i can do this?

I get these errors

Error   2   Argument 1: cannot convert from 'bool' to 'double'  C:\Users\Kyle\documents\visual studio 2010\Projects\Project Hat\Project Hat\MainGame.xaml.cs    33  46  Project Hat

Error	1	The best overloaded method match for ''System.Windows.Thickness.Thickness(double, double, double, double)'' has some invalid arguments	C:\Users\Kyle\documents\visual studio 2010\Projects\Project Hat\Project Hat\MainGame.xaml.cs	33	32	Project Hat

推荐答案

view.Margin.Top > 0是布尔值.
Thickness构造函数仅接受double.
传递布尔值没有任何意义.您到底想达到什么目的?

view.Margin.Top > 0 is a boolean.
The Thickness constructor accepts double only.
Passing a boolean doesn''t make sense. What exactly are you trying to achieve?

尝试三元运算符

Try ternary operator

new Thickness(view.Margin.Top>0?1:0, -1, 0, 0)
