如何在asp.net mvc中编写纯SQL？

Question

我创建了一个控制器类,如下所示:

public class CelebrityController : Controller
{
    private MyDatabase db = new MyDatabase();

    public ActionResult Index()
    {
        var query = db.tableCelebrity.Include(t => t.tableMovie);
        return View(query.ToList());
    }
}

现在我想做同样的事情,但在Index方法中使用纯SQL查询.我试图替换代码如下:

public class CelebrityController : Controller
    {
        private MyDatabase db = new MyDatabase();

        public ActionResult Index()
        {
            IEnumerable<tableCelebrity> results = db.ExecuteQuery<tableCelebrity>
            (@"SELECT c1.celebid as CelebrityID, t1.movieName as MovieName
                FROM tableCelebrity as c1, tableMovie as t1
                WHERE c1.celebid = t1.celebid");
        }
    }

但这给了我一个错误db.ExecuteQuery<tableCelebrity>:

错误'MyProject.Models.MyDatabase'不包含'ExecuteQuery'的定义,并且没有扩展方法'ExecuteQuery'接受类型为'MyProject.Models.MyDatabase'的第一个参数'

是否可以使用ASP.NET MVC？如果是,那么我必须在方法中执行哪些更改？

请帮我这样做.

I am created Details method as below

public ActionResult ShortDetails(int? id, string tagname)
    {
        tblCelebrity tblcelebrity = db.tblCelebrities.SqlQuery<tblCelebrity>("SELECT * FROM dbo.tblCelebrity WHERE Celebrity_ID =" + id);

        if (tblcelebrity == null)
        {
            return HttpNotFound();
        }
        return View(tblcelebrity);
    }

和详细信息查看接受类型为

@model MyProject.Models.tblCelebrity

我还在我的项目中创建了tblCelebrity类

但是`tblCelebrity tblcelebrity = db.tblCelebrities.SqlQuery("SELECT*FROM dbo.tblCelebrity WHERE Celebrity_ID ="+ id); 此行给出错误,因为非泛型方法'System.Data.Entity.DbSet.SqlQuery(string,params object [])'不能与类型参数一起使用

你想要类似的东西:

using (var context = new BloggingContext())
{
    var blogs = context.Blogs.SqlQuery("SELECT * FROM dbo.Blogs").ToList();
}
