如何从列表框中查找被选中的项目 [英] how to find the seleted items from list box

问题描述

受保护的无效btndelvoters_Click(对象发送者，EventArgs e)
{
试试
{


for(int i = 0; i< listboxvotersemail.Items.Count; i ++)
{
:laugh:如果(listboxvotersemail.SelectedItem.Selected == true)
{

Vote.deletevoters(UserId，binid，listboxvotersemail.SelectedItem.Text);
Vote.deleteUserEmail(UserId，listboxvotersemail.SelectedItem.Text);
}


}


}
赶上
{
}
}

protected void btndelvoters_Click(object sender, EventArgs e)
{
try
{


for (int i= 0; i < listboxvotersemail.Items.Count; i++)
{
:laugh: if (listboxvotersemail.SelectedItem.Selected==true)
{

Vote.deletevoters(UserId, binid, listboxvotersemail.SelectedItem.Text);
Vote.deleteUserEmail(UserId, listboxvotersemail.SelectedItem.Text);
}


}


}
catch
{
}
}

推荐答案

for (int i = 0; i < listboxvotersemail.Items.Count; i++)
{
      :laugh: if (listboxvotersemail.Items[i].Selected == true)
     {
                Vote.deletevoters(UserId, binid, listboxvotersemail.SelectedItem.Text);
                Vote.deleteUserEmail(UserId, listboxvotersemail.SelectedItem.Text);
     }
}

ListBox对象中有一个名为SelectedItems的集合，因此请尝试以下操作:

There is a collection in the ListBox object called SelectedItems, so try this:

foreach (MyObject item in listBox.SelectedItems)
{
   // do soemthing with the item
}
