我正在尝试使用下面的代码获取列表框中所选项目的值,但它总是返回空字符串.
I am trying to get the value of the selected item in the listbox using the code below, but it is always returning null string.
DataSet ds = searchforPrice(Convert.ToString(listBox1.SelectedItem));
这里我试图将所选项目的值作为字符串传递给方法 searchforPrice 以从数据库中检索数据集.
Here I am trying to pass the value of selected item as string to method searchforPrice to retrive dataset from the database.
如何将所选项目的值检索为字符串?
How can i retrive the value of selected item as string?
我正在从组合框向列表框添加项目,组合框又从数据库中加载项目.
I am adding items to listbox from combo box which in turn loads the items from the database.
listBox1.Items.Add(comboBox2.Text);
任何人都有答案..
如果要检索项目的显示文本,请使用 GetItemText
方法:

method:
string text = listBox1.GetItemText(listBox1.SelectedItem);
