首先将默认成员添加到代码中

Question

我在代码中几乎是新手。我希望ef在创建数据库时将默认成员添加到表中，例如： 表名：用户 默认成员：

        var user1 = new User() { Email = "u1@contoso.com", FirstName = "u1" };
        var user2 = new User() { Email = "u2@contoso.com", FirstName = "u2" };
        var user3 = new User() { Email = "u3@contoso.com", FirstName = "u3" };
        var user4 = new User() { Email = "u4@contoso.com", FirstName = "u4" };
        var user5 = new User() { Email = "u5@contoso.com", FirstName = "u5" };

我该怎么办？
