简单.

Simple.

OpenFileDialog fileD = new OpenFileDialog(); //create object

fileD.ShowDialog(); //show dialog
MessageBox.show(fileD.fileName); //Get uploaded file

所有您在CP上提出的问题属于基本水平.
我认为没有人会为这种简单的任务提供代码.
并且，请在发布到CP之前先查询您的查询，如果找不到其他合适的解决方案，可以在CP上询问.

这是您 answer [

All of your question asked on CP are of basic level.
