Add where clause in LINQ query

Question

Hello,

 

Requirement:  Need to get max SESSION_SRNO for particular LoginID

 

I have a method like this:

 

public long Get_Session_SrNo_Count(string userID)
{
HRMSContext Entities = this.HRMSRepository.Context as HRMSContext;
return Entities.t_login_info.ToList().Max(p => (long?)p.SESSION_SRNO).GetValueOrDefault();
} 

 

I need to add where clause in this query.

Ex: where p.LoginID == userID

 

 

Please Help.

 

Thanks in advance.
