rules="./src/main/resources/Rules.json"

如果没有，最好的方法是什么？

Answer 2

使用Guava替代ma3stro的答案：

public void Update(UserEntity person)
{
    UserEntity user = new UserEntity();
    SurveyEntities dbcontext = new SurveyEntities();

    var query = (from p in dbcontext.Users
                 where p.UserId == person.UserId
                 select new UserEntity() { UserId =p.UserId , FirstName = p.FirstName, LastName = p.LastName, Birth = p.Birth.Value, Password = p.Password, UserName = p.Username, Email = p.Email, Active = p.Active.Value }).SingleOrDefault();

    query.FirstName = person.FirstName;
    query.LastName = person.LastName;
    query.UserName = person.UserName;
    query.Password = person.Password;
    query.Email = person.Email;
    query.Birth = person.Birth;
    query.Active = person.Active;

    try
    {
        dbcontext.SaveChanges();
    }
    catch (Exception e)
    {
        Console.WriteLine(e);
        // Provide for exceptions.
    }
}
