mch.Machine_ID  is the hex value and mId is the string value.

How do I compare a Hex value to a string in LINQ to Entities Query string below?

var loc1 = (from mch in CRMEDM.edm1.m_Location
                         where mch.Machine_ID.ToString() == mId
                         select mch).ToList();

My error message: LINQ to Entities does not recognize the method 'System.String ToString()' method, and this method cannot be translated into a store expression.

What do you mean by "hex value"? A hexadecimal value is just a number, represented in a different base. If you're storing it as a number, then you should be comparing two numbers; otherwise, if you have this encoded as a hexadecimal string, then you should be able to do simple string comparison.
