Demo异步返回类型引用有误

https://github.com/donet5/SqlSugar/blob/094c75ed2f534e5e82727fda725743b0672555bd/Src/Asp.Net/PgSqlTest/Demo/Demo0_SqlSugarClient.cs#L327

Maybe:

if (result2.Result.IsSuccess == false)

看了下好像所有Demo中的事务用法这里都写错了~

是写错了OK我会改掉

[DotNetNext]

更新过了，以前异步事务用例也是错的

[DotNetNext]

 var result2 = db.UseTranAsync(async () =>
        {

            db.ChangeDatabase("1");//use db1
            await db.Deleteable<Order>().ExecuteCommandAsync();
            Console.WriteLine("---Delete all " + db.CurrentConnectionConfig.DbType);
            Console.WriteLine(db.Queryable<Order>().Count());

            db.ChangeDatabase("2");//use db2
            await db.Deleteable<Order>().ExecuteCommandAsync();
            Console.WriteLine("---Delete all " + db.CurrentConnectionConfig.DbType);
            Console.WriteLine(db.Queryable<Order>().Count());
            throw new Exception("");

        });
