在对象使得JSON无效的特殊字符（DataContractJsonSerializer） [英] Special characters in object making JSON invalid (DataContractJsonSerializer)

问题描述

我试图序列化具有特殊字符在他的琴弦的对象（如直径或℃）。

的问题是，当我使用这样的特殊字符，我的JSON的最后一位被切断？

如果没有特殊字符：

  {可用性：忙，名：测试，知名度：公共} 
  

使用特殊字符：

  {可用性：忙，名：托斯特，可见性：公
  

我注意到，每一个特殊字符，一个字符被切断我的JSON字符串。

我使用下面的代码序列化：

  //创建新的约会
 AppointmentClass任命=新AppointmentClass（）; 
 appoint.name = subjectstring; 
 appoint.availability =忙; 
 appoint.visibility =公开; 
 
 //生成预约类
 MemoryStream的流JSON字符串=新的MemoryStream（）; 
 DataContractJsonSerializer SER =新DataContractJsonSerializer（typeof运算（AppointmentClass））; 
 ser.WriteObject（流，委）; 
 stream.Position = 0; 
 StreamReader的SR =新的StreamReader（流）; 
串有效载荷= sr.ReadToEnd（）; 
  

解决方案

您需要使用UTF-8编码。这将是这样的。

  DataContractJsonSerializer SER =新DataContractJsonSerializer（typeof运算（AppointmentClass））; 
变种MS =新的MemoryStream（）; 
 serializer.WriteObject（MS，委）; 
 //使用UTF编码，接受特殊字符
 VAR MYTEXT = Encoding.UTF8.GetString（ms.ToArray（））;

I'm trying to serialize an object which has a special character in on of his strings (like ø or æ).

The problem is that when I use a special character like that, the last bit of my JSON is cut off?

Without special characters:

{"availability":"busy","name":"test","visibility":"public"}

With special characters:

{"availability":"busy","name":"tøst","visibility":"public"

I notice that for each special character, a character is cut off of my JSON string.

I use following code to serialize:

// create new appointment
AppointmentClass appoint = new AppointmentClass();
appoint.name = subjectstring;
appoint.availability = "busy";
appoint.visibility = "public";

// generate json string from Appointment class
MemoryStream stream = new MemoryStream();
DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(AppointmentClass));
ser.WriteObject(stream, appoint);
stream.Position = 0;
StreamReader sr = new StreamReader(stream);
string payload = sr.ReadToEnd();

解决方案

You need to use UTF-8 encoding. It will be something like this

DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(AppointmentClass));
    var ms = new MemoryStream();
    serializer.WriteObject(ms, appoint);
//use utf encoding to accept special chars
    var mytext = Encoding.UTF8.GetString(ms.ToArray());
