c# - 文件名、目录名或卷标语法不正确。 (来自 HRESULT : 0x8007007B) 的异常

Question

我在代码查找路径时收到此错误，我不明白这是什么时候发生的，我认为我做对了。

代码:

 string newUri = ImageGalleryUri.Replace("ms-appdatalocal/", "");  //Replace this part of the string with a nonspace character.
        newUri = newUri.Replace("/", "\\");
        newUri = newUri.Replace("%20", " "); //Replace the ASCII code for space for an actual space. For some reason I'm getting invalid character error with %20.
        StorageFolder folder = Windows.Storage.ApplicationData.Current.LocalFolder;
        StorageFile storageFile = await folder.GetFileAsync(newUri);
        DataPackage dp = new DataPackage();    //Create the DataPackage containing the clipboard content.
        dp.SetBitmap(RandomAccessStreamReference.CreateFromFile(storageFile));
        Clipboard.SetContent(dp);
        await successDialog.ShowAsync();

错误在这一行:newUri = ms-appdata:\local\Books\Assets\Recursos para el docente\Matematicas\9\Esp\1\0\Geometria_Page_04.png

StorageFile storageFile = await folder.GetFileAsync(newUri);

Answer 1

也许试试这个:

newUri = Uri.EscapeDataString(newUri);

代替:

newUri = newUri.Replace("%20", " ");
