Windows phone 8 StorageFolder GetFolderFromPathAsync Windows Phone 8

你好，我有这个密码

private async Task SaveImageToIsolatedStorage(Stream stream)
        {

            StorageFolder Datafolder = await ApplicationData.Current.LocalFolder.GetFolderAsync("Data");
            StorageFolder subfolder1 = await Datafolder.GetFolderAsync("subfolder1");
            StorageFolder subfolder2 = await subfolder1 .GetFolderAsync("subfolder2");

            StorageFile file = await subfolder2.CreateFileAsync("test.jpg", CreationCollisionOption.ReplaceExisting);
            using (Stream current = await file.OpenStreamForWriteAsync())
            {
                await stream.CopyToAsync(current);
            }

        }

StorageFolder folder= await ApplicationData.Current.LocalFolder.GetFolderAsync("Data\\subfolder\\subfolder1");

如果直接使用StorageFolder.GetFolderFromPathAsync（“数据\子文件夹1 \子文件夹2”）接收错误

{System.IO.FileNotFoundException:系统找不到指定的文件

如何？

根据msdn上的一篇帖子，您需要使用双斜杠：

StorageFolder.GetFolderFromPathAsync("Data\\subfolder1\\subfolder2")

好的，它与此代码一起工作

private async Task SaveImageToIsolatedStorage(Stream stream)
        {

            StorageFolder Datafolder = await ApplicationData.Current.LocalFolder.GetFolderAsync("Data");
            StorageFolder subfolder1 = await Datafolder.GetFolderAsync("subfolder1");
            StorageFolder subfolder2 = await subfolder1 .GetFolderAsync("subfolder2");

            StorageFile file = await subfolder2.CreateFileAsync("test.jpg", CreationCollisionOption.ReplaceExisting);
            using (Stream current = await file.OpenStreamForWriteAsync())
            {
                await stream.CopyToAsync(current);
            }

        }

StorageFolder folder= await ApplicationData.Current.LocalFolder.GetFolderAsync("Data\\subfolder\\subfolder1");
