更新 WPF 桌面桥通用应用程序时无法升级设置 [英] Can't upgrade settings when updating a WPF Desktop Bridge Universal app

问题描述

我的应用程序是用 WPF C# 编写的，我直接从 Visual Studio 使用 MSIX 应用程序项目将其导出为通用应用程序.

My app is written in WPF C# and I export it as Universal app using MSIX Application Project straight from Visual Studio.

我只是无法让设置在更新之间保持不变.我在 MainWindow_Loaded 事件中使用以下代码:

I just can't get the settings to persist between updates. I'm using the following code in the MainWindow_Loaded event:

Settings.Default.Upgrade();
Settings.Default.Save();
Settings.Default.Reload();

我尝试保持程序集信息版本相同，只是在 appx.manifest 中增加版本，但它不起作用.

I tried keeping assembly information versions the same and just increment the version in the appx.manifest but it doesn't work.

我注意到，每次应用更新时，它都会创建一个新的唯一命名的父设置文件夹(每次都有一个新的散列)，子文件夹名称是程序集的版本.文件夹结构是这样的:

I've noticed that each time the app updates it creates a new uniquely named parent settings folder (with a new hash every time) and the subfolder name is the version from the assembly. The folder structure is like this:

App.exe_Url_dfvfmfjs1qo33zsag1ay5w1s0rwg0u53/0.2.10.0/user.config

App.exe_Url_tazrvujdga5ujjarnahpkoscv5zbkgl0/0.2.10.0/user.config

我认为这可能与它不断生成新的哈希值有关，而不仅仅是将新版本作为子文件夹放置，这就是 Upgrade 不做任何事情的原因.

I believe it might have to do with the fact that it keeps generating new hashes instead of just placing the new version as a subfolder and that's why Upgrade doesn't do anything.

到目前为止我发现的唯一信息是使用 Settings.Default.Upgrade()

The only information I've found so far is to use Settings.Default.Upgrade()

当我的通用桌面桥应用更新时，我应该如何将旧版本设置转移到新版本?

How am I supposed to transfer the old version settings to the new version when my universal desktop bridge app updates?

推荐答案

据我研究，这些设置不会使用桌面桥传输到 UWP 更新.于是我开始使用 UWP 的原生 ApplicationData.Settings

As far as I researched these settings do not transfer to UWP updates using Desktop Bridge. So I started using UWP's native ApplicationData.Settings

作为一种解决方法，我创建了 2 种方法来使用 LocalSettings 更新新创建的 WPF 设置，这是 UWP 等效项，反之亦然.UWP 的 LocalSettings 传输更新.我在保存 WPF 设置时调用 Update()，在应用程序启动时调用 Load().它有效.

As a workaround I created 2 methods to update the newly created WPF settings using LocalSettings which is the UWP equivalent and vice versa. UWP's LocalSettings transfer on update. I call Update() when I save my WPF settings and I call Load() when the application starts. It works.

这是代码，到目前为止我发现的唯一警告是您应该使用基本类型，因为这些方法将无法传输诸如 List 或 StringCollection 之类的东西code>，为此我使用了序列化，尽管您也可以随时调整它们来执行此操作:

Here's the code, only caveat I've found so far is you should use the basic types as these methods will fail transferring something like a List<string> or a StringCollection, for that I'm using serialization, although you can always adapt them to do that too:

static class UWPSettings
    {
        public static void Update()
        {
            if (Startup.IsUniversalPlatform)
            {
                foreach (SettingsPropertyValue value in Properties.Settings.Default.PropertyValues)
                {
                    ApplicationData.Current.LocalSettings.Values[value.Name] = value.PropertyValue;
                }
            }
        }

        public static void Load()
        {
            if (Startup.IsUniversalPlatform)
            {
                foreach (var setting in ApplicationData.Current.LocalSettings.Values)
                {
                    foreach (SettingsPropertyValue s in Properties.Settings.Default.PropertyValues)
                    {
                        if (s.Name == setting.Key)
                        {
                            s.PropertyValue = setting.Value;
                        }
                    }
                }

                Properties.Settings.Default.Save();
            }
        }
    }
