Using .contains LINQ method doesn't work properly.

Question

Hello

 

I'm trying to convert SQL like command to LINQ 

 

 

select  EmployeeID,EnName from EmployeeMaintenance
where EmployeeID like '1'

 

in c# code i replace the 1 with variable, that will be any value, but in debug i provide the same value which is 1:

 

 

var test= _context.EmployeeMaintenances
                         .Where(c => c.EmployeeID.Contains(param.sSearch));

 

 But the result is the wohle list in the table EmployeeMaintenances !!?

 

can any one figure the problem?
