参数HTTP Post c＃

Question

I am making an HTTP POST method to get data. I have an idea to create a method to get a specific arguments but when I don't have idea to get the arguments taken. In HTTP GET, arguments are in the URL and is more easy to get the arguments. How do I create a method to take all the data in HTTP Post? In PHP for example when you show the var $_POST you show all data in the body post. How can I do this in C#?

My method is this:

[HttpPost]
[AllowAnonymous]
public IHttpActionResult Test()
{
// Get URL Args for example is 
var args = Request.RequestUri.Query;
// But if the arguments are in the body i don't have idea.
}

Web API has a feature which automatically binds argument posted to an action inside a controller. This is called Parameter Binding . It allows you to simply request the object inside the URL or the body of the POST request, and it does the deserialization magic for you using a thing called Formatters. There is a formatter for XML, JSON, and other known HTTP request types.

For example, lets say I have the following JSON:

{
    "SenderName": "David"
    "SenderAge": 35
}

I can create an object which matches my request, we'll call it SenderDetails :

public class SenderDetails
{
    public string SenderName { get; set; }
    public int SenderAge { get; set; }
}

Now, by receiving this object as a parameter in my POST action, I tell WebAPI to attempt to bind that object for me. If all goes well, I'll have the information available to me without needing to do any parsing:

[Route("api/SenderDetails")]
[HttpPost]
public IHttpActionResult Test(SenderDetails senderDetails)
{
    // Here, we will have those details available, 
    // given that the deserialization succeeded.
    Debug.Writeline(senderDetails.SenderName);
}

If I get you Correctly, in C# you use the [HttpPost] attribute to expose a post method.

[HttpPost]
public IHttpActionResult Test()
{
// Get URL Args for example is 
var args = Request.RequestUri.Query;
// But if the arguments are in the body i don't have idea.
}
