推荐答案

首先尝试创建一个新窗体(ChildForm)，在其中添加一个ListBox，
并创建一个公共函数来设置数据源.



然后在要搜索的表单中，尝试搜索XML并获取一个集合.
创建一个新的ChildForm实例，然后调用该方法来设置数据源.
并将表单显示为对话框.
尝试使用委托在selectionindex更改事件上传递数据.

谢谢，

First try to Create a new Form (ChildForm), Where you add a ListBox,
And create a public function to set the datasouce.



Then in the form where you are searching, Try to search the XML and get a collection.
Create a new instance of ChildForm and call the method to set the data source.
and show the form as a dialog.
Try to use delegate to pass data on selectionindex change event.
