C＃拖放删除

Question

我只是想知道如何从列表框中拖动项目并将其放入图像中，然后从列表框中删除该值。 这是我到目前为止的代码;

private void Form1_Load(object sender, EventArgs e)

{
textBox1.AllowDrop = true;
pictureBox1.AllowDrop = true;
}

private void listBox1_MouseDown(object sender, MouseEventArgs e)

{
if ( listBox1.Items.Count > 0 )
    listBox1.DoDragDrop(    /* ? */      , DragDropEffects.Move);    //This 
statement is incomplete!
}

private void textBox1_DragEnter(object sender, DragEventArgs e)

{
e.Effect = DragDropEffects.Move;
}

private void textBox1_DragDrop(object sender, DragEventArgs e)

{
//Code to copy selected List Box entry to Text Box and remove original entry
}

private void pictureBox1_DragEnter(object sender, DragEventArgs e)

{
e.Effect = DragDropEffects.Move;
}

private void pictureBox1_DragDrop(object sender, DragEventArgs e)
{
//Code to remove selected entry from List Box
}

任何帮助将不胜感激， 非常感谢
