如何将listBox选中的项目作为KeyValuePair <string, string> 在C＃？

Question

ListBox object is binded with BindingList<KeyValuePair<string, string>>

On SelectionChanged event I need to get selected item as KeyValuePair<string, string>

Following code gives error because KeyValuePair can't be used as reference type.

KeyValuePair<string, string> selectedProperty = listProperties.SelectedItem as KeyValuePair<string, string>;

What is good work-around for this?

Answer 1

尝试使用直接铸造的，而不是as ：

var selectedProperty = (KeyValuePair<string, string>)listProperties.SelectedItem;
