C# WebAPI parse Json data with extra braces

This may be a very rare scenario, but I ended up with a problem and not finding any solution.

I have a WebAPI controller written with MVC WebAPI in C#. I have a post method which receives the custom object. 

[HttpPost]
public HttpResponseMessage SendEmail([FromBody]Email email)
{

}

Below is the Email class, note that EmailData is of dynamic type.

public class Email
{
    public string EmailTo { get; set; }

    public dynamic EmailData { get; set; }
}

When I am sending JSON payloads as the post, EmailData property is adding extra curly braces '{}' into the object. This is giving me a problem because my dynamic data is not able to parse JSON with extra curly braces '{}'.

{
  "EmailFrom": "[email protected]",
  "EmailData": {
    "FirstName": "Rushi",
    "LastName": "Joshi"}
}

If this is happening because of the dynamic type, then I don't want to change type as I am not sure what all Key/Value requester may send. I am using dynamic data to extract data from it.

This shows EmailData being parsed and adding extra curly braces.

Thanks everyone, yes you all gave a wonderful answer and special thanks to Stevenfowler16, who describe that this is correct way JSON object should be processed.

Thing is I can't remove the dynamic object type as that is coming from some other library, also I can't change anything into the signature of API. but yes below thing helped me.

em.EmailData = System.Web.Helpers.Json.Decode(em.EmailData.ToString());

This serves my purpose but again thanks, everyone, your solution provide me some direction into it.

Regards

If you want to store the dynamic JSON in your Email class then you can use the Newtonsoft.Json package.

    public class Email
    {
        public string EmailTo { get; set; }

        public JOject EmailData { get; set; }
    }

It will store any type of the JSON. So you can parse the inner JSON object at runtime.

Use Dictionary object instead of dynamic, it will bind your key value pair data, 

    public class Email
    {
        public string EmailTo { get; set; }

        public Dictionary<string,string> EmailData { get; set; }
    }

Your json will be,

{
  "EmailTo": "[email protected]",
  "EmailData": {
    "FirstName": "Rushi",
    "LastName": "Joshi"}
}

The JSON provided is valid: https://jsonlint.com/

An object with more than one property will always return in that format. 

"EmailData": {
    "FirstName": "Rushi",
    "LastName": "Joshi"}

This is an EmailData object with two name/value pairs.You have an object nested inside your original object.

Here is some documentation to read up on for further clarification. https://www.json.org/
