Question

I am trying to update a POCO using lin2sql. I can also use entity framework. For updating objects I follow the next routine.

//GridView Control gives me some updated POCOS As an Example: Person updated;

 function UpdatePerson(Person myUpdatedPersonfromUI)
  {
   using (Entity con = new Entity() ) {
     var recordFromdB = from obj in con.Person where obj.PK = myUpdatedPersonfromUI.PK 
            select obj;
      Person personOnDB = recordFromdB.Single();


        // now for each column I update personOnDB

            personOnDB.Property1 =   myUpdatedPersonfromUI.Property1 ;    
            personOnDB.Property2 =   myUpdatedPersonfromUI.Property2 ;  
            personOnDB.Property3 =   myUpdatedPersonfromUI.Property3 ;  
            personOnDB.Property4 =   myUpdatedPersonfromUI.Property4 ;  
       // continue updating fields              ...
                  ..
                  .                             
            personOnDB.Property124 =   myUpdatedPersonfromUI.Property124 ;  


             con.SaveChanges();



    }
  }

Do I have to update each property manually . Please help .

You can use an object mapping tool like AutoMapper which pretty much will do the work for you – in this simple case (property names match between source and target) it would be a one-liner to map these.
