获取字符串值从QueryMultiple导致

Question

在我dotNetCore之后，我发现，通过使用QueryMultiple返回多个结果的查询......

这是我的查询

var sql = @"SELECT CountryId as Id, CountryName as Name FROM country; 
      SELECT CityId as Id, CityName as Name, CountryId FROM city; 
      SELECT CitizenshipId as Id, CitizenshipName as Name FROM citizenship; 
      Select Count(user.UserId) as totalUserCount 
          FROM identityuser user;"; 

这是我是如何获取其结果为可变

using (IDbConnection dbConnection = new DbManager().Connection) 
      { 
       dbConnection.Open(); 

       var grid = dbConnection.QueryMultiple(sql, new 
       { 
       }); 

       manageProfileView.countries = grid.Read<Country>().ToList(); 
       manageProfileView.cities = grid.Read<City>().ToList(); 
       manageProfileView.nationalities = grid.Read<CitizenShip>().ToList(); 
      } 

现在我怎么能得到这个查询的数据

Select count（user.UserId）as totalUserCount FROM identityuser user;

我已经试过这样的事情

VAR = USERCOUNT grid.Read（）ToList（）。

但是它没有返回有效数据，有没有更好的办法从grid变量中获得简单计数。

我相信，你只需要得到你的列表中相应的计数，请尝试：

var userCount = grid.Read().ToList().Count;
