我使用以下代码从列表中填充列表框:
uList.Add(new KeyValuePair<int, string>(item.Id, item.Name));
listBoxHome.DataSource = uList;
listBoxHome.DisplayMember = "Value";
listBoxHome.ValueMember = "Key";
然后我以新的对话框形式(Subtitiution)复制所有项目,并填写checkedListBox1
private void button6_Click(object sender, EventArgs e)
{
Sub sub = new Sub();
for (int i = 0; i < listBoxHome.Items.Count; i++)
{
sub.checkedListBox1.Items.Add(listBoxHome.Items[i].ToString());
}
this.Opacity = 0.7;
sub.ShowDialog();
}
然后,我将所选项目的选定索引放入列表中。 我想选择5个项目,然后将它们放在listbox的前5个位置。游戏是第一个表单。我尝试以下代码,但它给了我错误。有什么想法吗?
private void button2_Click(object sender, EventArgs e)
{
List<int> indexes = new List<int>();
foreach (int indexChecked in checkedListBox1.CheckedIndices)
{
indexes.Add(indexChecked);
}
Game game = new Game();
foreach (int PlayingInd in indexes) // Loop through List with foreach
{
game.listBoxHome.Items.Insert(0, game.listBoxHome.Items[PlayingInd]);
game.listBoxHome.Items.RemoveAt(PlayingInd);
}
this.Close();
}
