How can I get DataAnnotations.Compare to compare properties from 2 different objects?

Question

I'm getting an error using the view below

The property Models.m_Join.Member.password could not be found.

The 'Password' field that the error refers to is part of the 'member' object that is in the m_Join model.

I've tried using : -

    [System.ComponentModel.DataAnnotations.Compare("member.password", ErrorMessageResourceType = typeof(Resources.errors), ErrorMessageResourceName = "passwordsDontMatch")]

    [System.ComponentModel.DataAnnotations.Compare("member_password", ErrorMessageResourceType = typeof(Resources.errors), ErrorMessageResourceName = "passwordsDontMatch")]

But neither of them work.

public class m_Join
{

    public Member member { get; set; }

    [System.ComponentModel.DataAnnotations.Compare("password", ErrorMessageResourceType = typeof(Resources.errors), ErrorMessageResourceName = "passwordsDontMatch")]
    public string passwordConfirm { get; set; }


}

What do I have to use to get the code to compare member.password and passwordConfirm

Edit: The 2 properties I want to compare are in different objects. The properties in the proposed duplicate question are in the same object

您是否尝试过为此创建一个方法，该方法将两个值都分配给字符串，然后进行比较并返回一个布尔值？
