如何在WPF中将对象数据类型转换为UIElement

Question

I declared an object data type

object itemize;

then i created a method with conditions, depending on the condition, the itemize will be assigned into a corresponding UserControl

public void StackFilter(string mode)
{
    this.stkFilter.Children.Clear();

    switch(mode)
    {
        case "FilterWithType":
            itemize = new FilterWithTypesUC();
            break;
        case "FilterBasic":
            itemize = new FilterBasicUC();
            break;
    }
    this.stkFilter.Children.Add(itemize);
}

it says I can't add the itemize as the stack panel's child because it is not an UIElement type. Ho how do I make it as UIElement?

Answer 1

将元素转换为UIElement即

this.stkFilter.Children.Add(itemize as UIElement);

Answer 2

I'll suggest you to declare it as UIElement itself. Then you don't need a cast.

UIElement itemize;
