How to send a MIME message as is

[Ryan H]

Hi,

I've been using WebClient.UploadFile to upload a XML file to a URL via HTTP
POST. I now have to build something that attaches another file (PDF) to the
XML file and upload that.

I found out how to create a Multipart MIME Message but I don't know how to
send it as is. I tried using WebClient.UploadFile but it doesn't work since
it sends my Multipart MIME Message using MIME.

How do I send my Multipart MIME Message as is?

Here is the Multipart MIME Message I'm trying to send:


POST /cXML HTTP/1.0
Content-Type: multipart/mixed;boundary=-----_asdfasdfasdf;
type="text/xml"; start="<[email protected]>"

I've been using WebClient.UploadFile to upload a XML file to a URL via HTTP

Not a language question, so I'm setting f'up to .general.

Using WebClient.UploadString() should keep your data as-is.

POST /cXML HTTP/1.0
Content-Type: multipart/mixed;boundary=-----_asdfasdfasdf;
type="text/xml"; start="<[email protected]>"

Note that the POST isn't part of the message, neither is the Content-Type.
The former is added automatically and the latter should be set through
WebClient.Headers.
