Converting from a dynamic data type in c# to a .net Object

I have a method that receives some data from a 3rd party. The data is a JSON object (not a string, I tried receiving as a string and data was not accessable - the data property was null)

[HttpPost]
 [Route("com/sendemail")]
 public async Task<IActionResult> SendEmail(dynamic data)
 {
       mailData = JsonConvert.DeserializeObject<EmailTemplate>(data);
 }

I am trying to get it into a .net object which is needed to be passed into another function I dont control. It has to be an EmailTemplate object, which is defined as:

public class EmailTemplate
{
        public string From { get; set; }
        public string To { get; set; }
        public string Subject { get; set; }
        public string EmailHtml { get; set; }
}

mailData is of type EmailTemplate. The Deserialize object call fails because that method requires a string, which this isnt. Ive tried other methods, such as

mailData = (EmailTemplate)data;

and

mailData.To = data.To

but neither work. Any pointers gratefully received.

PS. Heres what the data looks like in visual studio

When your class matches the Json-object that is sent, this will work:

public async Task<IActionResult> SendEmail([FromBody]EmailTemplate data)

When you use your dynamic approach, you need to access the dynamic objects members and create your .NET object with them.

public async Task<IActionResult> SendEmail([FromBody]dynamic data)
{
    mailData = new EmailTemplate {
        From      = data.From,
        To        = data.To,
        Subject   = data.Subject,
        EmailHtml = data.EmailHtml
    };
}

Your controller couldn't accept a string, because (I assume) the request's content-type is 'application/json' and the framework couldn't convert it to a string. You should change your controller's data parameter type to EmailTemplate:

[HttpPost]
[Route("com/sendemail")]
public async Task<IActionResult> SendEmail([FromBody] EmailTemplate data)
{
    //...
}
