LINQ Update Problem RRS feed

  • Question

  • Hi All, I am using LINQ in my application . While updating data i am getting below problem..

     " GenericArguments[2], System.Int32 , on System.Data.Linq.Mapping.PropertyAccessor+Accessor`3[T,V,V2] violates the constraint of type V2 "

     Here is my code
    ServiceOfferedPosting == CLASS 

    ServiceOfferedPosting objAcc = GetServiceOfferedPostingByID(Convert.ToInt32(str[k]));
     (objAcc != null
     objAcc.IsBlocked = blnIsBlock;
    objAcc.LastUpdateDate = DateTime.Now;
     (FarmlinkDataContext dc = conn.GetContext())
     dc.ServiceOfferedPosting.Attach(objAcc, true

     the same thing i am doing for other classes and it is working fine.. but for this class it is giving error..
    Please tell me why this error is coming ?

  • Sorry I didn't see your question before - I would have moved it to the correct forum, because this certainly is not the right one. Please say what sort of LINQ you are using, so I can move the question to the appropriate forum.

  • Can you show the definition of ServiceOfferingPosting and GetServiceOfferedPostingByID ?
