Can RestSharp send binary data without using a multipart content type?

Question

I have been using AddParameter to include XML bodies in my HTTP requests:

request.AddParameter(contentType, body, ParameterType.RequestBody);
         


        

Answer 1

I had the same issue. Turned out that RestSharp behaves in a little odd way.

NOT WORKING:

request.Parameters.Add(new Parameter() {
  ContentType = "application/x-www-form-urlencoded",
  Type = ParameterType.RequestBody,
  Value = bytes
});

WORKING (Add content-type as name):

request.Parameters.Add(new Parameter() {
  Name = "application/x-www-form-urlencoded", // This is the 'funny' part
  ContentType = "application/x-www-form-urlencoded",
  Type = ParameterType.RequestBody,
  Value = bytes
});

I tried this solution based on a comment here: https://github.com/restsharp/RestSharp/issues/901

which states "...name value will be used as Content-Type Header and contentType value will be ignored."

You dont have to add the value as the Content-Type parameter as well, but I fear that a future bug-fix might change the behaviour and then requiring the Content-Type to be used instead of name.
