拖放到桌面/浏览器 [英] Drag and drop to Desktop / Explorer

问题描述

随着我的方案。

我得到了一个应用程序，它加载一个Filestructure（文件夹，文件），从数据库到一个WPF的ListView。现在，我想从这个ListView中获取文件，将它拖到了我的台式机（或打开资源管理器窗口），并把它在那里。基本拖放，没有什么花哨。这听起来像一个标准功能的Windows应用程序 - 但谷歌不会帮助

I got an Application which loads a Filestructure (Folders, Files) from a Database into a WPF ListView. Now I'd like to grab a file from this ListView, drag it over my Desktop (or some open explorer window) and drop it there. Basic Drag and Drop, nothing fancy. This sounds like a "standard" function for a windows application - but google won't help.

所以，我怎么能做到这一点？互操作性展示？

So how can I achieve this? Interops?

感谢

修改：谢谢你的解决方案，我还是不得不做一些谷歌上搜索。 这是我的完整的解决方案。

Edit: Thanks for the solution, I still had to do some googling. Here's my complete solution.

推荐答案

DragDrop.DoDragDrop 能做到这一点，只要你把它传递一个合适的数据对象。

DragDrop.DoDragDrop can do this as long as you pass it an appropriate DataObject.

首先某处复制文件。您可以使用 System.IO.Path.GetTempPath（）如果你没有地方好。

First copy the files somewhere. You can use System.IO.Path.GetTempPath() if you don't have anywhere better.

接下来创建一个字符串数组，包含的完整路径的文件，并执行以下操作：

Next create a string array containing the full paths to the files and do the following:

string[] paths = ...;
DragDrop.DoDragDrop(this, new DataObject(DataFormats.FileDrop, paths),
                    DragDropEffects.Copy); 

这其实是可以做到这一点没有pre-复制文件但进入一些复杂的IDataObject的互动，所以，除非您的文件可能非常大，是不是已经在文件系统中我先试试这个方法

It is actually possible to do this without pre-copying the files but that gets into some complicated IDataObject interactions, so unless your files are potentially very large and aren't already in the filesystem I would try this method first.
