How to loop throught Listbox

I use this code, but its not working.
Any idea?

For Each item As String In lstmnth.SelectedItem.Value
       MessageBox.Show(item.ToString())
Next

推荐答案

首先，您应该遍历lstmnth.Items而不是lstmnth.SelectedItem.Value，因为它只有一个值.

其次，MessageBox不能在ASP.NET中使用，它不能作为Windows Form东西使用.

First of all, you should be looping through lstmnth.Items and not lstmnth.SelectedItem.Value as it has only one value.

Second, MessageBox does not work in ASP.NET, its as Windows Form thingie.

好吧，这是适合您的C#代码段.希望您可以将其转换为VB.NET

Well, here is C# Snippet for you. Hope you can convert it into VB.NET

foreach (ListItem s in listControl.Items)
     {
         Response.Write(s.Value);
     }

希望对您有所帮助！

Hope this will help you !
