C# 如何在asp.NETMVC4中一次点击两个表id保存到第三个表中

我是在asp.NETMVC4C中创建工作门户的，我在申请工作时遇到了问题 我正在创建三个表格：求职者、PostJobs和ApplyJobs

求职表

PostJobs表

应用作业表

---

单击应用按钮，在ApplyJob表中保存用户ID和采购订单ID当前用户ID

你的问题不太清楚

如果您担心求职者的Id和自动生成的PostJob表

或者做类似的事情

Jobseeker js = new Jobseeker();
....
//assign your property to js instance
....
PostJob pj = new PostJob();
....
//assign your property to pj instance
....
ApplyJob aj = new ApplyJob();
aj.jobseeker = js; // assign it to navigation property and ef will handle ids
aj.Postjobs = pj; // assign it to navigation property and ef will handle ids
//Add to dbsets here
Context.SaveChanges();

暗示

您不需要第三个表，因为它看起来像多对多关系。因此，如果您不想在第三个表中处理插入，您可以通过在JobPost中声明ICollection和在Jobseeker类中声明ICollection来避免，这将强制您创建第三个表，该表将由EF维护和操作

这里有几个链接供你参考

所以，问题是如何在表中插入行还是什么？不清楚您在问什么！
