Question

我一直在尝试使用Entity框架浏览sqlite db文件并读取数据。但是以下方式不起作用我用sqlite文件路径启动MydbContext 例如

 using (var sourceContext = new MydbContext(@"D:\test\data.sqlite"))
            {
               var a= sourceContext.MyModel.ToList();
            }

  public MydbContext(string path)
           : base(GetConnectionString(path))
        {
            Configuration.LazyLoadingEnabled = false;
        }

 public static string GetConnectionString(string path)
        {
var entityConnectionString = new EntityConnectionStringBuilder
            {
                Metadata = "res://*",
                Provider = "System.Data.SQLite.EF6",
                ProviderConnectionString = sqlLiteConnectionString,
            }.ConnectionString;
}

请使用sqlite和ef。建议是否有正确的方法来实现这一目标。

得到了评论的答案

 private static SQLiteConnection GetConnectionString(string path)
        {
            var con= new SQLiteConnection()
            {
                ConnectionString =
              new SQLiteConnectionStringBuilder()
              { DataSource = path, ForeignKeys = true,BinaryGUID = false }
              .ConnectionString
            };

            return con;
        }

Entitiy框架和sqlite作为文件路径不起作用
