Change DbSet with table name

Question

I would like to know how to change DbSet on a DbContext using a table name (instead of using a fix DbSet as in the example). I've tried this solution but with no results.

        var type = Assembly.GetExecutingAssembly()
            .GetTypes()
            .FirstOrDefault(t => t.Name == tablename);

        DbSet dsContext = DbContext.Set(type);

        var data = DbContext.dsContext 
            .Where(r => r.C_NUMERICID == idLinea)
            .Where(r => r.C_TIMESTAMP > startDate)
            .OrderBy(r => r.C_TIMESTAMP)
            .ToList();

DbContext does not contain the defintion of 'dsContext'

`but with no results.` Tell us more about what you mean by that. — mjwills, Feb 06 '18 at 11:40
I do have two derived types `public virtual DbSet IMA { get; set; } public virtual DbSet SEZIONATRICE { get; set; }` With tablename == 'SEZIONATICE' I get that error — Massimo Variolo, Feb 06 '18 at 13:44
why don't just you write `var data = dsContext.Where(r => r.C_NUMERICID == idLinea) ...` ? — jbl, Feb 07 '18 at 10:46

I was querying wrong. This is the working solution.

type = Assembly.GetExecutingAssembly()
   .GetTypes()
   .FirstOrDefault(t => t.Name == kepwareTableName);
IQueryable data = DbContext.Set(type)
   .Where($"C_NUMERICID == {idLinea}")
   .Where("C_TIMESTAMP > @0", startDate)
   .OrderBy("C_TIMESTAMP");
return data ;
