The probleem seems to be that your cs variable is a collection of customers. So when you have this little lambda expressions p =>p.empid=cs.employeeid it is not clear which employeeid should be taken. Is it the employeeid of the first customer, of the last customer or somewhere in between? Try passing in a single customer or specify which element from the list you want.
Alternatively, if cs is already a single customer (in which case you should change your class name of Customers to Customer) it might be that employeeid is nullable[^]. Nullable types[^] have a Value Property[^] which you should use if you want to compare it's value to another value. You might need to use the HasValue Property[^] first to check if it actually has a value so that no Exception occurs.
Hope it helps!
