推荐答案

我想问题就出在这一行：

I guess the problem is in this line:

m_SelectedBrand = e.Result;

检查m_SelectedBrand是否为int，如果是这样你应该像这样把e.Result转换为int：

Check if m_SelectedBrand is and int,and if so you should cast e.Result to int like this:

m_SelectedBrand =(int) e.Result;

当然，如果e.Result是int，这将有效。如果不是，则必须将此值存储在不同类型的变量中

Of course,this will work if e.Result is an int. If if isn't,you'll have to store this value in a different type of variable
