How to parse JSON body in C# HttpPost method

Question

I want to parse a JSON body and return the contents in a HttpPost method in C#.

The JSON body contains the following information:

{
    "name": "John",
    "age": "20"
}

[HttpPost]
public async Task<IActionResult> Test() 
{
return new JsonResult(new { items = new string[] { name, age } });

}

I want the method to return:

John 20

Answer 1

try this

public class ViewModel
{
    public string Name {get; set;}
 public int Age {get; set;}
}

[HttpPost]
public JsonResult Test([FromBody ViewModel model]) 
{
return new JsonResult(new {  name= model.Name, age=model.Age } });

}

you don' t need async since you don't have any async methods inside of the action

Answer 2

If I'm getting the question correctly, you want only to return string of John 20 then you can directly use:

return Ok($"{name} {age}")
