I have entity model created in Visual Studio 2010.This is part of my code:
Database1Entities1 de = new Database1Entities1();
UserInfo ui = new UserInfo();
ui.Name = "xxx";
ui.Username = "xxx";
ui.Password = "xxx";
de.UserInfoes.AddObject(ui);
It executes without problems, but new data is no added in the table. Does anybody know what the problem is?
You would need to call
de.SaveChanges();
if this is Entity Framework to persist the changes back to the database.
添加对象后,需要在de上调用save方法。
