我在ASP.NET Identity项目中使用MVC，我需要在ASP.NET Identity AspNetUsers实体和我的自定义表之间创建实体关系。众所周知，AspNetUsers表格使用字符串表示 ID 字段，并且此 ID中包含 GUID 值场。但是，我不确定以下问题：
1）我应该在自定义类中使用哪种数据类型来创建PK/FK关系？ 字符串或 GUID ？
2）如何为每个新记录自动生成此自定义 ID 字段？是否也可以使它sequential以便记录可以排序？
答案 0 :(得分：1)
1 - 你应该使用<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css" rel="stylesheet"/>

。 （见this）
如果您打开string，则会看到edmx中的Id（GUID）为AspNetUser。
2 - 您可以在模型中使用构造函数并生成GUID，如下所示：
string 3- 顺序Guid生成器请参阅this。我建议public partial class Student
{
public Student()
{
Id = System.Guid.NewGuid().ToString();
}
//Other fileds
}
。
