移动模拟器Windows 10的SQLite UWP错误

Question

我在尝试编译和运行VS 2015 UWP应用程序时运行Mobile Emulator时出现以下错误.使用本地计算机或模拟器时,应用程序运行正常.

   System.TypeInitializationException was unhandled by user code
  HResult=-2146233036
  Message=The type initializer for 'SQLitePCL.raw' threw an exception.

            at SQLitePCL.raw..cctor()

我有以下参考:SQLite for Universal Windows 3.9.1 sqlite-net-pcl Microsoft Visual C++ 2013 Runtime Package for Universal Windows

"using(var db ......:)中出现错误的代码

 int recCtr = 0;
        var root = Windows.Storage.ApplicationData.Current.LocalFolder.Path;
        var dbPath = Path.Combine(Windows.Storage.ApplicationData.Current.LocalFolder.Path, "BaseBallOU.db");
        List<string> NHLCollection = new List<string>();
        using (var db = new SQLite.SQLiteConnection(dbPath))
        {
            var NHLlist = db.Table<Teams>().ToList();
            foreach (var item in NHLlist)
            {
                recCtr++;
                NHLCollection.Add(item.TeamName.ToString());
            }
        }

我看到了许多类似的帖子,但有些是过时的,没有使用最新的SQLite库和pcls.

我正在寻找正确的SQLite dll,sqlite pcls,运行时(例如VC++ 2013？以及可用于在本地计算机和手机模拟器上编译和运行UWP应用程序的版本号.

TIA

Answer 1

以下是我如何使用SQLite:

1. 从http://sqlite.org/download.html下载并安装Sqlite visual studio扩展

2. 创建一个新的空白c#通用Windows平台应用程序.

3. 右键单击项目的引用 - >添加引用 - >通用Windows - >扩展 - >为通用应用程序平台添加SQLite及其依赖项Visual C++ 2015 Runtime for Universal Windows

4. 右键单击项目节点 - >管理NuGet包 - >搜索SQLite.Net-PCL - >安装默认版本3.0.5

5. 将您的代码更改为以下内容:

   using (var db = new SQLite.Net.SQLiteConnection(new SQLite.Net.Platform.WinRT.SQLitePlatformWinRT(), dbPath))
   {
       ...
   }
