推荐答案

使用无类型表可能不那么容易.组合框具有用于列表框的Text属性:

That may not be so easy with untyped tables. A Combobox has a Text property, for the listbox:

 textbox3.Text = listBox1.SelectedItem;

为您提供项目"，但这可能是DataRowView.您可以投放它:
((DataRowViw) SelectedItem).Row[3]

Gets you the 'item' but that probably is a DataRowView. You can cast it :
((DataRowViw) SelectedItem).Row[3]
