如果用户想插入多个电话号码和电子邮件地址，我想同时从视图中删除多个电话号码和电子邮件地址。

直到工作正常但如何实现电话号码和电子邮件地址？

感谢。

Answer 1

您需要将手机和电子邮件分解为自己的类，然后在它们和Employee之间添加一对多关系：

public class Phone
{
    public string Phone { get; set; }
}

public class Email
{
    public string Email { get; set; }
}

public class Employee
{
    ...

    public virtual ICollection<Phone> Phones { get; set; }

    public virtual ICollection<Email> Emails { get; set; }
}

.net mvc视图中的一对多关系
