Newtonsoft.JSON serializeobject返回空的JSON字符串 [英] Newtonsoft.JSON serializeobject returns empty JSON string

问题描述

每个人都有很多问题，我几乎尝试了所有方法，但对我来说都不起作用.

Everyone got this question a lot, and I tried almost everything but none of it works for me.

因此，我正在Xamarin.Forms中进行开发，即将把我的数据发送到服务器.我有这个课:

So I am developing in Xamarin.Forms and is about to send my data to the server. I have this class:

public class Customer
{

    public string FirstName { get; set; }
    public string LastName { get; set; }
    public string BirthDate { get; set; }
    public string Password { get; set; }
    public string EmailAddress { get; set; }
    public string ContactNumber { get; set; }

}

然后我使用了Newtonsoft的SerializeObject方法:

Then I used Newtonsoft's SerializeObject method:

Customer customer = new Customer
        {
            FirstName = FirstName.Text,
            LastName = LastName.Text,
            BirthDate = BirthDate.Date.ToString(),
            EmailAddress = Email.Text,
            Password = Password.Text,
            ContactNumber = Mobile.Text
        };


        var item = JsonConvert.SerializeObject(customer);

但是变量item会导致包含空JSON对象{}的字符串.我的实现有问题吗?

But variable item results in a string containing an empty JSON object {}. Is something wrong with my implementation?

另外，我注意到，尽管我的Customer类及其成员是公共的，但调试器仍将它们视为非公共"成员.请参阅调试器的屏幕截图":

Also, I noticed that although my Customer class and its members are public, the debugger still counts them as "non-public" members. Please see "screenshot of debugger":

推荐答案

Xamarin Live Player似乎与序列化程序有关.我尝试通过USB插入手机，并且可以正常工作！

It appears that Xamarin Live Player has some issues with the serializer. I tried plugging my phone via USB and it works!
