Configuration.Save 在网络驱动器上

Question

我为一些简单的任务开发了一个 Winforms 应用程序。此应用程序有一个 App.config 文件，其中保存了一些设置。我在应用程序中创建了一个标签页，我可以在其中使用 Configuration class. I save to the App.config using a 'Save' button in the application itself which uses the Configuration.Save.

调整配置文件的设置

但是我在将配置文件保存到网络文件夹时遇到了问题。当我将设置保存到本地文件夹（如：C:\）上的文件时，一切都很好。我的意思是我将 .exe 和 .config 复制到网络文件夹（例如：\\folder\application.exe），当我尝试使用 Configuration.Save 将我的设置保存到配置文件时，我得到以下错误：

System.UnauthorizedAccessException: Attempted to perform an unauthorized operation.

编辑：或者我可以只使用 StreamWriter 而不是配置吗？

这是堆栈跟踪：

该文件可能是以管理员身份在该位置创建的，这将使其无法被任何其他非管理员用户使用。

您需要设置文件权限以允许所有人都喜欢这样

private void CreateSettingsFile(string path)
    {
        XDocument document = new XDocument();
        XElement rootElement = new XElement("settings");
        document.Add(rootElement);
        document.Save(path);
        var accessControl = File.GetAccessControl(path);
        var everyone = new SecurityIdentifier(WellKnownSidType.WorldSid, null);
        accessControl.AddAccessRule(new FileSystemAccessRule(everyone,
                                                            FileSystemRights.FullControl |
                                                            FileSystemRights.Synchronize,
                                                            AccessControlType.Allow));

        manager = new XmlSettingsManager(document, () => XDocument.Load("file://" + Path.Combine(AppDomain.CurrentDomain.BaseDirectory, this.settingsPath)),
            x => x.Save(this.settingsPath));
        File.SetAccessControl(path, accessControl);
    }
