问题描述
我有 listbox1 - 它的数据源是一列(产品名称).
I have listbox1 - its datasource is a column (productname).
所以我在列表框中有一个 MultiSelection 选项.
so i have in the listbox a MultiSelection option.
我正在尝试为我选择的所有选项制作一个 MessageBox 代码:
and im trying to make a MessageBox for all the option i selected and this the code:
foreach (object selectedItem in listBox1.SelectedItems)
{
MessageBox.Show((selectedItem.ToString() + Environment.NewLine));
}
问题是我得到了这个值System.Data.DataRowView
推荐答案
如何填充列表框(即数据源到底是什么)?
How do you populate the listbox (ie what is exactly the datasource)?
根据您的评论，我会说一个 DataView(其中包含 DataRowView...)
From your comment I would say a DataView (and wich contains DataRowView...)
因此，您只需要将 SelectedItem 转换为 DataRowView 即可从此 DataRowView 中获取值:
So you just need to cast the SelectedItem into DataRowView in order to get a value from this DataRowView:
foreach (object selectedItem in listBox1.SelectedItems)
{
DataRowView dr = (DataRowView)selectedItem;
String result = dr["productname"].ToString;
MessageBox.Show(result + Environment.NewLine);
}
