你会得到那个价值因为你的数据绑定到

ComboBox而被退回。将SelectedValue转换为DataRowView，然后您可以从Row属性和所需列中获取

适当的值。

你好，我正在尝试获取comboBox值但是当我写作时：
MessageBox.Show（this.comboBoxdb.SelectedValue.ToSt ring（））;
我得到以下结果：
系统.Data.DataRowView
而不是选定的值。为什么？

谢谢，但我铸造失败 - 我怎么能这样做（我试图创建新的

DataRowView而不是将SelectedValue指向它但它没有工作）

怎么办它？

谢谢！

Hello ,I am trying to get the comboBox value but when I am writing:
MessageBox.Show(this.comboBoxdb.SelectedValue.ToSt ring());
I get the following result:
System.Data.DataRowView
instead of the selected value . Why?

You''ll get that "value" being returned because you''re data binding to the
ComboBox. Cast the SelectedValue to a DataRowView and then you can get the
appropriate value from the Row property and desired column.
