linq - Date comparision

In LINQ, I write a query for data, which is between two dates. In this case I am not getting data. When user enters same date as from date and to date the data is not displaying while there are data for that particular date.

This is my LINQ query.

var result =  from MaterialStatus in materialRequistionEntities.Tbl_MatReq_NewItemReq_M
join CurrentStatus in materialRequistionEntities.Tbl_StatusMaster_M 
    on MaterialStatus.ReqCurStatus equals CurrentStatus.StatusId
join Employee in materialRequistionEntities.Tbl_Emp_Master_M
    on MaterialStatus.Indentor equals Employee.EmpId
where (MaterialStatus.CreatedOn >= dt.Date 
    && MaterialStatus.CreatedOn <= dt1.Date)
select *****************

You should do:

var upperDate = dt1.Date.AddDays(1);
...
where (MaterialStatus.CreatedOn >= dt.Date
    && MaterialStatus.CreatedOn < upperDate

This way the expression can be converted to a sargable SQL predicate.
