使用DataContractJsonSerializer创建Non XML Json文件 [英] Using DataContractJsonSerializer to create a Non XML Json file

问题描述

我想使用DataContractJsonSerializer序列化为JsonFormat中的文件。
问题是 WriteObject 方法仅具有3个选项XmlWriter，XmlDictionaryWriter和Stream。

I want to use the DataContractJsonSerializer to serialize to file in JsonFormat. The problem is that the WriteObjectmethod only has 3 options XmlWriter, XmlDictionaryWriter and Stream.

To得到我想要的东西，我使用了以下代码：

To get what I want I used the following code:

var js = new DataContractJsonSerializer(typeof(T), _knownTypes);
using (var ms = new MemoryStream())
{
   js.WriteObject(ms, item);
   ms.Position = 0;
   using (var sr = new StreamReader(ms))
   {
      using (var writer = new StreamWriter(path, false))
      {
         string jsonData = sr.ReadToEnd();
         writer.Write(jsonData);             
       }
   }
}

这是唯一的方法还是我错过了什么吗？

Is this the only way or have I missed something?

推荐答案

假设您只是想将文本写到文件中，不清楚为什么首先将其写入 MemoryStream 。您可以使用：

Assuming you're just trying to write the text to a file, it's not clear why you're writing it to a MemoryStream first. You can just use:

var js = new DataContractJsonSerializer(typeof(T), _knownTypes);
using (var stream = File.Create(path))
{
    js.WriteObject(stream, item);
}

这很简单，应该做您想要的...

That's rather simpler, and should do what you want...
