写入InstalledLocation遇到的文件“Access is Denied” （0X80070005）！ [英] Write to the file in the InstalledLocation encounter "Access is Denied" (0x80070005)!

问题描述

在InstalledLocation中读取文件工作正常，但无法写入此文件。

Read file in the InstalledLocation works fine, but can't write to this file.

如何修复这个问题？

StorageFolder folder = Package.Current.InstalledLocation.
                GetFolderAsync(@"Settings").AsTask().Result;
            StorageFile file = folder.GetFileAsync(@"Settings.json").AsTask().Result;
            string jsonString = FileIO.ReadTextAsync(file).AsTask().Result;
            var rootObject = JsonObject.Parse(jsonString);
            rootObject["set1"]= JsonValue.CreateStringValue("ok");
            FileIO.WriteTextAsync(file, rootObject.Stringify()).AsTask().Wait();

推荐答案

在你的问题中，你正试图写入安装目录，它会给出错误。此行为是预期的。因为应用程序的安装目录是只读位置。这在文档中提到：应用程序
安装目录。您可以参考此文档以获取有关文件访问权限的更多信息。

In you question, you are trying to write into the install directory and it gives the error. This behavior is expected. Because the app's install directory is a read-only location. This is mentioned in the document here:Application install directory. You could refer this document for more information about file access permissions.

祝您好运，
