DataContractJsonSerializer和JsonConvert给出不同的结果 [英] DataContractJsonSerializer and JsonConvert give different result

问题描述

我有这样的方法.

using (MemoryStream memoryStream = new MemoryStream())
{
    DataContractJsonSerializer dataContractSerializer = new DataContractJsonSerializer(typeof(Message), this.knowTypes);
    dataContractSerializer.WriteObject(memoryStream, message);

    byte[] byteArray = memoryStream.ToArray();
    memoryStream.Close();
    return byteArray;
}

当我将byteArray转换为字符串时，结果如下: {"__ type":登录名:#Project.ProjectName.Sockets"，密码":"F9AAD6B7CFBD2A756101"，用户名":"UserName"}

When I convert the byteArray to string the result is like below: {"__type":"Login:#Project.ProjectName.Sockets","Password":"F9AAD6B7CFBD2A756101","Username":"UserName"}

此结果对我的服务器有意义.

This result is meaningful my server.

但是由于某些字符问题，我想更改此代码.

However I want to change this code with because of some character issues.

byte[] byteArray = System.Text.Encoding.UTF8.GetBytes(JsonConvert.SerializeObject(message));
return byteArray;

现在，我将byteArray转换为字符串，结果如下: {"Username":"UserName"，"Password":"F9AAD6B7CFBD2A756101"}

Now I convert byteArray to string the result like: {"Username":"UserName","Password":"F9AAD6B7CFBD2A756101"}

我也尝试使用 JsonSerializerSettings

 settings = new JsonSerializerSettings();
 settings.TypeNameAssemblyFormat = System.Runtime.Serialization.Formatters.FormatterAssemblyStyle.Full;
 settings.TypeNameHandling = TypeNameHandling.Objects;

，结果是 {"$ type":"Project.ProjectName.Sockets.Login，ProjectName"，"Username":"UserName"，"Password":"F9AAD6B7CFBD2A756101"}

DataContractJsonSerializer和JsonConvert有什么区别，并且可以使用JsonConvert获得相同的结果.

What is the difference between DataContractJsonSerializer and JsonConvert and it is possible to get same result using JsonConvert.

推荐答案

将以下设置传递给 DataContractJsonSerializer ，并且永远不要获取任何类型信息:

Pass the following settings to the DataContractJsonSerializer and you should never get any type information:

DataContractJsonSerializerSettings settings = new DataContractJsonSerializerSettings()
{
    EmitTypeInformation = EmitTypeInformation.Never
};
