you should use NewtonSoft.Json if you need to serialize objects as json

I would use Json.Net to create the JSON payloads for sure (Afterall, Microsoft does for Web Api).

Nuget Package Source:

<pre><code>Install-Package Newtonsoft.Json
</code></pre>

Here is an example. If you want to call a REST api that returns a product when you make a GET call then you might do something like this.

<pre><code>public static class Main
{
 string url = "https://TheDomainYouWantToContact.com/products/1";
 HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(url);
 request.Method = "GET";
 request.ContentType = "application/json";
 request.Accept = "application/json";
 var httpResponse = (HttpWebResponse)request.GetResponse();

 var dataStream = httpResponse.GetResponseStream();
 var reader = new StreamReader(dataStream);
 var responseFromServer = reader.ReadToEnd();
 reader.Close();
 dataStream.Close();

 // This is the code that turns the JSON string into the Product object.
 Product productFromServer = JsonConvert.Deserialize&lt;Product&gt;(responseFromServer);
 Console.Writeline(productFromServer.Id);
}

// This is the class that represents the JSON that you want to post to the service.
public class Product
{
 public string Id { get; set; }
 public decimal Cost { get; set; }
 public string Name { get; set; }
 public string Description { get; set; }
}
</code></pre>

The exact same method can be used for POST and PUT as well.

You can use 3rd party assemblies to make this super easy too. We are the authors of DynamicApis.Api

<pre><code>Install-Package DynamicApis.Api
</code></pre>

The code to make the same request using this client would be:

<pre><code>public static class Main
{
 RestClient client = new RestClient();
 string url = "https://YourDomain.com/products/1";
 var productFromServer = client.Get&lt;Product&gt;(url);
 Console.Writeline(productFromServer.Id);
}
</code></pre>

blocks|key|2083952|text|您不应该做任何特殊的事情来发送Json数据。默认的输出格式化程序已经是Json，如果您的Startup.cs文件有点正常，您应该有一行类似的代码：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2083953|services.AddMvc();|code-block|syntax|javascript|2083954|默认情况下，这已经包含Json格式化程序，您的控制器应该根据浏览器要求的内容自动协商返回类型。因此，如下所示的控制器应该工作(取自这个吉特布问题，其中包含一些关于为什么/如何工作的信息)：|offset|length|2083955|public+class+ValuesController+:+ApiController

You shouldn't have to do anything special to send back Json data. The default output formatter is already Json, and if your Startup.cs file is somewhat normal, you should have a line similar to this:

<pre><code>services.AddMvc();
</code></pre>

By default, this already contains the Json formatter, and your controller should autonegotiate the return type based on what the browser asked. So a controller like the following should work (taken from <a href="https://github.com/aspnet/Mvc/issues/1765" rel="nofollow">this Github issue</a>, which contains some information on why/how this work):

<pre><code>public class ValuesController : ApiController
{
 public SomeClass Get()
 {
 return new SomeClass();
 }

 public SomeClass Post([FromBody] SomeClass x)
 {
 return x;
 }
}
</code></pre>

I am trying to create a JSON object in a .Net 5 application. The default options I am presented with are <code>Microsoft.AspNet.Mvc.Formatters.Json</code>, <code>Microsoft.Extensions.Configuration.Json</code>, and <code>Newtonsoft.Json</code> when I use the Visual Studio 2015 Qucik Actions on <code>Json</code>. My understanding is that <code>Configuration.Json</code> is for reading form the <code>appsettings.json</code> so it probably is not what I would use to create a JSON object. I can't find any real information on <code>Formatters.Json</code>, how to use it, or what it's intended use it. <code>Newtonsoft.Json</code> is will documented but is it better over the <code>Formatters.Json</code>? Which of the two should I be using?
