[UWP] Windows 10拖放问题 [英] [UWP]Windows 10 Drag&Drop problem

问题描述

Hello

我有Windows Universl App，可以修改文件。现在我尝试添加一个从其他应用程序删除文件的功能（这与Windows 10一起提供），但是我发现当我调用
时我得到的文件

I have Windows Universl App which allows to modify files. Now I trying to add an ability to Drop Files from other app(this comes with Windows 10), but I've found that files I get when I call

DataView.GetStorageItemsAsync

DataView.GetStorageItemsAsync

都是ReadOnly，我没有找到改变这种情况的方法。

are all ReadOnly and I didn't find the way to change this situation.

有没有办法获得带有"读写"访问权限的文件 来自Windows 10 UWP应用程序中的D& D？

Is there a way to get files with ReadWrite access  from D&D in Windows 10 UWP app?

是的，据我所知，从Drag and Drop访问的所有文件都是ReadOnly。此问题的一种解决方法是将文件复制到本地存储，之后您可以读取和写入此复制的文件：

Yes, as far as I know all those file which accessed from the Drag and Drop are ReadOnly. One workaround for this issue is to copy the file to your Local storage, after that you can Read and Write this copied file:

           var files = await e.DataView.GetStorageItemsAsync();
            foreach (var storageItem in files)
            {
                var file = storageItem as StorageFile;
                if (file != null)
                {
                  
                    //copy file to LocalFolder
                    var newCopyFile = await file.CopyAsync(ApplicationData.Current.LocalFolder, file.Name, NameCollisionOption.ReplaceExisting);

......
