问题描述
请告诉我如何获取 ListBox
的 ValueMember
?我已经阅读了许多教程,但仍然无法解决.任何帮助将不胜感激.
Please tell me how can I get ValueMember
of ListBox
SelectedItems
? I have read many tutorials but still I am unable to solve it. Any help will be greatly appreciated.
int c = subjects_Listbox.Items.Count - 1;
for (int i = 0; i >= 0; i--)
{
if (subjects_Listbox.GetSelected(i))
{
txt.Text += subjects_Listbox.SelectedIndices[i].ToString();
txt.Text += ", ";
}
}
推荐答案
您的 for
循环不正确.只需尝试一下(这将遍历您的 ListBox
的所有 SelectedIndices
,并将它们添加到您的 TextBox
中):
Your for
loop is incorrect. Just try this (this iterate through all SelectedIndices
of your ListBox
and will add them to your TextBox
):
foreach (var item in subjects_Listbox.SelectedIndices)
{
txt.Text += item;
txt.Text += @", ";
}
甚至更好:
txt.Text = string.Join(",", subjects_Listbox.SelectedIndices.Cast<int>());
