使用poster发送数据时嵌套模型不绑定

当我尝试使用WebAPI2放置数据时,获取对象引用错误。我的班级结构就像这个
public class Student
{
public int Id { get; set; }
public string Name { get; set; }
public string Email { get; set; }
public Address address { get; set; }
}
public class Address
{
public int Id { get; set; }
public int StudentId { get; set; }
public string City { get; set; }
public string AddressLine { get; set; }
}
我的看跌期权方法如下
public async Task putStudentProfile(Student student)
{
tblStudent std= db.tblStudent .FirstOrDefault(p => p.ID == student.Id);
std.NAME = student.Name;
std.EMAIL= student.Email;
tblAddress addr= db.tblAddress.FirstOrDefault(q => q.ID == student.Id);
addr.City= student.address.City;
await db.SaveChangesAsync();
}
使用邮递员发送JSON数据。我的JSON数据如下
{
"Id":59,
"Name": "Sandeep",
"Email": "xxxxxxxx@xxxx.com",
"address":{
"Id":42,
"StudentId": "59",
"City": "xxxxxx",
"AddressLine":"xxxxxxxxxxxxx"
}
}
尝试访问student.address.City
时出现对象引用错误
有解决这个问题的办法吗?
javascript对象的格式不正确,需要使用点表示法(与访问控制器中属性值的方式相同)
{
"Id":59,
"Name": "Sandeep",
"Email": "xxxxxxxx@xxxx.com",
"address.Id": 42,
"address.StudentId": 59,
"address.City": "xxxxxx",
"address.AddressLine": "xxxxxxxxxxxxx"
}
