Question

I can use datediffmin() method in SQL, but is there a same method in Linq? Say one field in my table is GeneratedTime which is datetime type. I want to select all records that generated within the last 20min.

    return(from m in dc.Msgs
           where m.GeneratedTime ????
           select m)

Answer 1

This should do the trick:

return (from m in dc.Msgs
        where m.GeneratedTime > DateTime.Now.AddMinutes(-20)
        select m)
