推荐答案

您可以做在一个单一的循环。你应该将selectedIndices使用一个简单的和循环向后：

You could do all in a single loop. You should use a simple for and loop backwards on SelectedIndices:

private void button1_Click(object sender, EventArgs e) 
{ 
    for(int x = listBox1.SelectedIndices.Count - 1; x>= 0; x--)
    { 
        int idx = listBox1.SelectedIndices[x];
        listBox2.Items.Add(listBox1.Items[idx]); 
        listBox1.Items.RemoveAt(idx);
    } 
}
