推荐答案

在此示例中，我假设您要拖动&的列表视图中有人"列表.

启动拖放操作.放在来源"例如这样的listview面:

Hi,

In this example I assume that you have list of Persons in the listviews you want to drag & drop between source and target listviews.

Initiate the drag & drop on the "source" listview side like this for example:

私有 void listViewSource_ItemDrag( 对象 发件人，ItemDragEventArgs e)

{

font style ="color:blue">如果 ( this .listViewSource.SelectedIndices.Coun t> 0)

{{

List< Person> selectedPersons = 新 List< Person>();

foreach <字体样式="font-size:11px">( int 索引 输入 此 selectedPersons.Add(.sourceList [index]);

}

font style ="color:blue">此 .listViewSource.DoDragDrop(selectedPersons，DragDropEffects.Copy || DragDropEffects.Move);

}

private void listViewSource_ItemDrag(object sender, ItemDragEventArgs e)

{

if (this.listViewSource.SelectedIndices.Count > 0)

{

List<Person> selectedPersons = new List<Person>();

foreach (int index in this.listViewSource.SelectedIndices)

{

selectedPersons.Add(this.sourceList[index]);

}

this.listViewSource.DoDragDrop(selectedPersons, DragDropEffects.Copy | DragDropEffects.Move);

}

}
