在一个视图中使用多个模型.net Mvc
是的，在一个视图中有多种方法可以使用多个模型。我从那里选择一个选项=＆gt;并创建一个额外的类，并将这些多个类添加到该类=＆gt;
合并的class =＆gt;
public class combo
{
public IEnumerable<User> User { get; set; }
public IEnumerable<StudentRegistrationViewModel> StudentRegistrationViewModel { get; set; }
public IEnumerable<StudentFullRegistrationViewModel> StudentFullRegistrationViewModel { get; set; }
}

但问题是它显示了一些错误，例如=＆gt;
上面的第一张图片给了我错误，这就是为什么我没有改变所有=＆gt;（并且也没有xowing me intellisense）=＆gt;
我也尝试=＆gt;
public class combo
{
public User User { get; set; }
public StudentRegistrationViewModel StudentRegistrationViewModel { get; set; }
public StudentFullRegistrationViewModel StudentFullRegistrationViewModel { get; set; }
}
那个人也没有工作。请帮助我吗？
1 个答案:
答案 0 :(得分：2)
这就是为什么你的组合成员用户是IEnumerable of Users
public IEnumerable<User> User { get; set; }
所以你有多个用户不能只有一个控件来操纵它们（你的所有用户） 因此，如果您需要让单个用户只需将您的班级定义更改为
public User User { get; set; }
或者如果您需要拥有多个用户对象，请使用foreach并将每个用户对象绑定到单个控件
