Hello Prasad, please follow these code for inserting and updating you can do at a time for an example write an operation in your service interface file as UpsertStudent in this way, if it success it gives you the value as true if not false namespace WCFandEFService { [ServiceContract] public partial interface IPrasad { [OperationContract] bool UpsertStudent( Student student); } [DataContract] public class Student { [DataMember] public int StudentID { get; set; } [DataMember] public string StudentName { get; set; } [DataMember] public string StudentField{ get; set; } [DataMember] public string StuentGrades { get; set; } } } Than next in your .svc file public partial class PrasadService: IIPrasad { public bool UpsertStudent( Student student) { Entities dbcontext = new Entities (); Student existingstu = dbcontext.Students.Where( dl =>dl.StudentID== student.StudentID).FirstOrDefault(); // if the existing students count not equal to null you will update their values with new values if (existingstu != null) { existingstu.StudentName = student.StudentName; existingstu.StudentField = student.StudentField; existingstu.StudentGrades = student.StudentGrades; } // else if existing is null you will insert the new student into database else { Student s = new Student { StudentID = student.StudentID , StudentName = student.StudentName , StudentField= student.StudentField, StudentGrades = student.StudentGrades }; dbcontext.Students.Add(s) } // try to make changes to the database if everything goes well it returns the value as true try { dbcontext.SaveChanges(); return true; } catch { return false; } }
