windows运行时组件中的sqlite

问题描述

我正在尝试在 Windows 运行时组件中使用 sqlite.但是当我添加 nuget sqlite-net 包时，我收到了一些 219 错误.无法在任何地方弄清楚.有没有类似的问题?

am trying to use sqlite in a windows runtime component. But I get some 219 errors when i add the nuget sqlite-net package. couldnt figure it out anywhere. Any similar issues ?

我最终使用商店应用类库来使用 sqlite 并从我的 Windows 运行时组件调用其中的这些方法.

I finally used a store app class library to use sqlite and called those methods in it from my windows runtime component.

商店应用程序中的方法

   public async  Task<IEnumerable<TaskGroup> > GetTaskGroup()
    {
         return await conn.QueryAsync<TaskGroup>("select * from TaskGroup");

    }

win 运行时组件中的调用方法

calling method in win runtime component

public IAsyncOperation<IEnumerable<TaskGroup>> GetAllTaskGroup()
    {
        return m_objDAL.GetTaskGroup().AsAsyncOperation();

    }

我收到以下错误

Error   1   Method 'Tasker.BAL.TaskManager.GetAllTaskGroup()' has a parameter of type 'Windows.Foundation.IAsyncOperation<System.Collections.Generic.IEnumerable<SQLLite.Models.TaskGroup>>' in its signature. Although this generic type is not a valid Windows Runtime type, the type or its generic parameters implement interfaces that are valid Windows Runtime types. Consider changing the type 'SQLLite.Models.TaskGroup' in the method signature. It is not a valid Windows Runtime parameter type.   

将商店应用程序方法设为私有可根据此博客解决该问题http://rarcher.azurewebsites.net/Post/PostContent/23

making the store app method as private resolves it as per this blog http://rarcher.azurewebsites.net/Post/PostContent/23

但我不能这样做，因为它会给我带来访问问题，因为它是私密的.

but i cant ue this since it will give me access issues since it is private.

有什么解决办法吗?

推荐答案

我不明白这些错误是什么，但是您是否首先通过工具">扩展"安装 SQLite for Windows Runtime?sqlite-net 是 LINQ 查询库

I don't understand what these errors are, but did you first install the SQLite for Windows Runtime through Tools > Extensions? sqlite-net is LINQ query library
