推荐答案

我将假设您已将列表框绑定到数据表.如果是这样，我本人就无法使用SelectedValue.

我发现有效的方法是使用以下方法来获取选定的值:

I''m going to assume that you have the listbox bound to a datatable. If so, I''ve had trouble with the SelectedValue myself.

What I''ve found works is to use the following to get the selected value:

Listbox.SelectedItems(X)(Listbox.ValueMember)

只需将"Listbox"替换为控件的名称，将"X"替换为要获取其值的所选项目的索引.

如果一次只允许1个选择，则可以将"X"硬编码为0.

祝你好运！

Just replace "Listbox" with the name of your control, and "X" with the index of the selected item you''re getting the value for.

If you''re only allowing 1 selection at a time, then you can hardcode the "X" as 0.

Good luck!

如果您有一个字符串，并且想要从中获取值，可以查看

If you have a string and you want to get the value out of that, you can have a look at this[^] and use the convert method.
