This depends on what content do you have. You need to initialize your requestMessage.Content property with new HttpContent. For example:

...
// Add request body
if (isPostRequest)
{
    requestMessage.Content = new ByteArrayContent(content);
}
...

where content is your encoded content. You also should include correct Content-type header.

UPDATE:

Oh, it can be even nicer (from this answer):

requestMessage.Content = new StringContent("{\"name\":\"John Doe\",\"age\":33}", Encoding.UTF8, "application/json");

I implemented it in the following way  I wanted a generic MakeRequest method that could call my API and receive content for the body of the request - and also deserialise the response into the desired type  I create a Dictionary lt string  string gt  object to house the content to be submitted  and then set the HttpRequestMessage Content property with it   Generic method to call the API       private static T MakeRequest lt T gt  string httpMethod  string route  Dictionary lt string  string gt  postParams   null                using  var client   new HttpClient                          HttpRequestMessage requestMessage   new HttpRequestMessage new HttpMethod httpMethod       apiBaseUri   route                  if  postParams    null                  requestMessage Content   new FormUrlEncodedContent postParams        This is where your content gets added to the request body               HttpResponseMessage response   client SendAsync requestMessage  Result               string apiResponse   response Content ReadAsStringAsync   Result              try                                  Attempt to deserialise the reponse to the desired type  otherwise throw an expetion with the response from the api                  if  apiResponse                            return JsonConvert DeserializeObject lt T gt  apiResponse                   else                     throw new Exception                              catch  Exception ex                                throw new Exception   An error ocurred while calling the API  It responded with the following message   response StatusCode   response ReasonPhrase                                     Call the method       public static CardInformation ValidateCard string cardNumber  string country    CAN                     Here you create your parameters to be added to the request content         var postParams   new Dictionary lt string  string gt       cardNumber   cardNumber       country   country                 make a POST request to the  cards  endpoint and pass in the parameters         return MakeRequest lt CardInformation gt   POST    cards   postParams
