c# - Post XML as "application/xml" instead of "text/xml" via RestSharp -

i'm hooking salesforce bulk api using restsharp.

when add object using addbody:

var request = new restrequest( method.post); request.requestformat = dataformat.xml; request.addheader("x-sfdc-session", loginresult.sessionid); var ji = new jobinfo { operation = "insert", @object = "contact", contenttype = "csv" }; request.addbody(ji, xmlns); 

salesforce rejects error message:

unsupported content type: text/xml

... presumably because behind scenes restsharp interpreting request.requestformat = dataformat.xml; "text/xml".

by fiddling around salesforce api have discovered wants "application/xml" instead of "text/xml".

is there supported way make restsharp send "application/xml" instead?

from documentation here

requestbody

if parameter set, value sent body of request. 1 requestbody parameter accepted – first one.

the name of parameter used content-type header request.

so:

var ji = new jobinfo { operation = "insert", @object = "contact", contenttype = "csv" };  var jiserialized = /* serialize ji xml format */  request.addparameter(new parameter {     name = "application/xml",     type = parametertype.requestbody,     value = jiserialized  })
