我新的實體框架。我有一個簡單的類:實體框架自動生成主鍵
public class User
{
[System.ComponentModel.DataAnnotations.Schema.DatabaseGenerated(System.ComponentModel.DataAnnotations.Schema.DatabaseGeneratedOption.Identity)]
public int UserId { get; set; }
public string Email { get; set; }
public string UserName { get; set; }
public string Password { get; set; }
//public UserList Users { get; set; }
public User() { }
public User(int userId, string email, string username)
{
UserId = userId;
Email = email;
UserName = username;
}
}
我的初始化器類:
public class UserDataInitializer : DropCreateDatabaseAlways<UserDataContext>
{
protected override void Seed(UserDataContext context)
{
var Users = new List<User> {
new User() {UserId=1, Email="[email protected]", UserName="a1", Password="123456"},
new User() {UserId=2, Email="[email protected]", UserName="a2", Password="123456"},
new User() {UserId=3, Email="[email protected]", UserName="a3", Password="123456"},
new User() {UserId=4, Email="[email protected]", UserName="a4", Password="123456"}}
Users.ForEach(i => context.Users.Add(i));
context.SaveChanges();
}
}
想,我要添加新的用戶用戶id = 100。它會自動更改用戶ID爲5
我如何可以禁用EF的這種修改?「用戶ID」必須是主鍵,它的類型是int。
使用。 DatabaseGenerated(System.ComponentModel.DataAnnotations.DatabaseGeneratedOption.None)]'。 –
