如何专门设置实体之间的关系 [英] How to specifically setup a relationship between entities

问题描述

您好，我正在使用mvc5创建一个Web应用程序，该应用程序具有个人资料页面，图库和youtube页面。

现在，我已经设法通过自定义IdentityUser来构建配置文件页面.cs包括其他属性但我在画廊方面遇到困难。我已经建立了相当不错的课程，但我不知道如何设置它以我想要的方式工作。

我希望每个用户都有一个画廊页面所以我'我认为我仍然应该将其作为IdentityUser.cs中的属性添加，或者我应该将其设置为profile.cs的外键，如果是这样，我很难理解实体之间的关系。请，即使你想给我一个链接来增进我的理解，请帮助我构建我所解释的那种我需要的关系。请。我是c＃的新手，也是网络应用的好人。



公共类画廊{

public int Id {get; set;}

public string Picture {get; set;}

public string Name {get; set}

public string说明{get; set;}

}

解决方案

Hello, i am creating a web application using mvc5 that has a profile page, galleries, and youtube page.
Now, i have manage to construct that of the profile page by customizing the "IdentityUser.cs" to include additional properties but i am stuck when it comes to gallery aspect. I have the class built up quite alright but i don't know how to go about setting it up to work the way i want it to.
I want each user to have a gallery page so i'm thinking should i still add this as a property in "IdentityUser.cs" or should i set it as a foreignkey to profile.cs and if so i am having hard time understanding relationships between entities. Please, even if you want to give me a link to boost my understanding, kindly help me in constructing the kind of relationship i have explained that i need. Please. I am new to c# and its good in web apps.

Public class Galleries{
public int Id {get;set;}
public string Picture {get;set;}
public string Name {get;set}
public string Description {get;set;}
}

解决方案
