Code First Entity Framework - 列返回 null 因为 EF 将名称更改为包含 _ID

Question

Entity framework changed the column name in the DB, and isn't giving me it's value.

Here are my classes:

public class Settings
{
    [Key]
    public int ID { get; set; }
    public string Setting { get; set; }
    public string MoreDetail { get; set; }
    public SettingTypes Type { get; set; }
    public SettingGroups SettingGroup { get; set; }
    public int? MinMembership { get; set; }
    public string DefaultValue { get; set; }
    public int? ParentID { get; set; }
    public int Order { get; set; }
}

public class SettingTypes
{
    [Key]
    public int ID { get; set; }
    [MaxLength(35)]
    public string TypeName { get; set; }
}

public class SettingGroups
{
    [Key]
    public int ID { get; set; }
    [MaxLength(35)]
    public string GroupName { get; set; }
}

In the DB you can see that it changed the name of the two columns:

When I try to loop through the results, type is null:

How do I retrieve this value? I've tried renaming the columns in the class and in the DB but that just breaks more things. What's the proper way to handle this?

Thanks!

Answer 1

Dangit, I figured it out. Spent way to much time doing so.

It was as simple as adding "virtual" to the properties:

        public virtual SettingTypes Type { get; set; }
        public virtual SettingGroups SettingGroup { get; set; }

Now I can address it like: setting.Type.TypeName

Hope this saves someone else some time.
