C-从JSON字符串结果提供viewModel

很好的一天,

在提取JSON字符串并在视图模型中提供它时,我需要一个帮助。

在我的示例中,我有一个视图模型,它有两个类。

课程:

public class Student {
    public int StudentId {get;set;}
    public string Firstname {get;set;}
    public string Lastname {get;set;}
}

public class Address {
    public int AddressId {get;set;}
    public string Street {get;set;}
}

视图模型:

public class StudentAddressViewModel{
    public Student Student {get;set;}
    public Address Address {get;set}
}

控制器:

public async Task<IActionResult> Create(IFormCollection studentInfo){
    // wherein studentInfo is the key
    ...
}

在我的控制器中,我发送这个JSON字符串。

{[studentInfo,{"Student":{"firstname":"Johhny","lastname":"Bravo"},"Address":{"street":"New york street..."}])

我正在尝试:

var studentInfo = studentInfo["studentInfo"];

var value = JsonConvert.DeserializeObject<Dictionary<string,string>>(studentInfo);

var studentVm = new StudentAddressViewModel{
    new Student{
        Firstname: value["firstname"], Lastname: value["lastname"]
    },
    new Address{
        Address: value["address"]
    }
}

但是我没有 value .

有什么帮助吗?
