Let’s say you want to insert new education into education table
Fist create object form current context
3,4 check the inserting object already exists if not insert the object to Educations collections.
context.SaveChanges() means save modification to the data base permanently
Result >0 means no error successfully inserted.
C#
using System.Data.Objects
string educationName = "English";
Entities context = new Entities();
Education insertingObject = context.Educations.FirstOrDefault(c => c.EducationName == educationName);
if (insertingObject == null) {
Education newEducation = new Education();
newEducation.EducationName = "English";
newEducation.EducationDescription = "English Decription";
context.Educations.AddObject(newEducation);
dynamic result = context.SaveChanges();
}
