将SQLite表存储在ObservableCollection中？

Question

public ObservableCollection<AppUser> AppUser { get; set; }

public AppUserDbConnect(string dbPath)
{
    _database = new SQLiteAsyncConnection(dbPath);
    _database.CreateTableAsync<AppUser>().Wait();
    this.AppUser = new ObservableCollection<AppUser>(_database.Table<AppUser>());
}

此代码创建数据库连接，然后基于AppUser模型创建表。我试图存储最后一行的结果，但我面临以下错误：

  

CS1503参数1：无法转换   Dialler1.DatabaseConnection.AsyncTableQuery<AppUser>来   System.Collections.Generic.IEnumerable<AppUser>

Answer 1

为db.Table<T>()

调用 ToList

 this.AppUser = new ObservableCollection<AppUser>(_database.Table<AppUser>().ToList());
