为多列表框中的每个选定项目实现循环

Question

我正在尝试为多列表框foreach中的每个所选项目实施UserProfileTrainingSearch循环：

if (UserProfileTrainingSearch.SelectedValue != "-1" && //other conditions)
{
    foreach (var ListBoxItem in UserProfileTrainingSearch.SelectedValue) // only the first item selected is giving the results.
    {
        Session["UserbyTrainingType"] = "SELECT DISTINCT USERPROFILE.USER_ISN, USERPROFILE.LAST_NAME + ',' ..........................;
        SqlUserProfile.SelectCommand = (string)Session["UserbyTrainingType"];
    }
}

Answer 1

foreach (ListBoxItem item in UserProfileTrainingSearch.SelectedItems)
{
   // your code here
}
