ListBox的问题!

[cantops]

我做了两个listbox,希望通过button来实现items在两个listbox之间相互移动.
在button的Click事件里我加入了如下代码

for(int i=0;i<(int)lstLeft.Items.Count;i++)
{
if (lstLeft.Items[i].Selected)
{
lstRight.Items.Add(lstLeft.Items[i]);
lstLeft.Items.Remove(lstLeft.Items[i]);
}
}
为什么这段代码无法实现我预期的效果呢?每逢偶数索引时items都不会移动.郁闷中

用js来做

private void Movebtn_Click(object sender, System.EventArgs e)
{
int Count = ListBox1.Items.Count;
int Index = 0;
for(int i=0;i<Count-1;i++)
{
ListItem Item = ListBox1.Items[Index];
if(ListBox1.Items[Index].Selected == true)
{
ListBox1.Items.Remove(Item);
ListBox2.Items.Add(Item);
Index--;
}
Index++;
}
}

private void Upbtn_Click(object sender, System.EventArgs e)
{
//若不是第一行则上移
if( ListBox1.SelectedIndex > 0 )
{
string name = ListBox1.SelectedItem.Text;
string ID = ListBox1.SelectedItem.Value;
int index = ListBox1.SelectedIndex;
ListBox1.SelectedItem.Text = ListBox1.Items[index-1].Text;
ListBox1.SelectedItem.Value = ListBox1.Items[index-1].Value;
ListBox1.Items[index-1].Text = name;
ListBox1.Items[index-1].Value = ID;
ListBox1.SelectedIndex --;
}
}

private void Downbtn_Click(object sender, System.EventArgs e)
{
//若不是最后一行则下移
if( ListBox1.SelectedIndex >= 0 && ListBox1.SelectedIndex < ListBox1.Items.Count-1 )
{
string name = ListBox1.SelectedItem.Text;
string ID = ListBox1.SelectedItem.Value;
int index = ListBox1.SelectedIndex;
ListBox1.SelectedItem.Text = ListBox1.Items[index+1].Text;
ListBox1.SelectedItem.Value = ListBox1.Items[index+1].Value;
ListBox1.Items[index+1].Text = name;
ListBox1.Items[index+1].Value = ID;
ListBox1.SelectedIndex ++;
}
}
}
