Hallo Stefan,
keine Sorge, das ist nur ein Beispielcode den ich bekommen habe.
Die richtige Verbindung geht natürlich über HTTPS.
Mich interessier eigentlich nur ob man das was im Beispielcode mit der
HttpWebRequest Klasse gemacht wird auch mit WebClient.UploadFile möglich ist.
In der WebClient Klasse finde ich keine Möglichkeit den CookieContainer zu setzen
und wie kann ich
string stringDataRFC = boundary + "\n" +
"Content-disposition: form-data; name=\"multiple\"\n\n" + "false\n" + boundary + "\n" +
"Content-Disposition: form-data; name=\"id\"\n\n" + issueID + "\n" + boundary + "\n" +
"Content-Disposition: form-data; name=\"Attach\"\n\n" + "Attach\n" + boundary + "\n";
...
damit realisieren? Ist WebClient.UploadFile für sowas gedacht?
Gruß
Ralf

ich hab folgenden Beispielcode bekommen, um einen Datei Upload von .NET
aus durchzuführen. (UploadFileWithPost)
Dieser Code ist recht aufwendig und ich hab versucht das Gleiche mit
UploadFile zu machen, hatte aber keinen Erfolg. (siehe
AddAttachmentToIssue2)
Kann mir jemand sagen, was noch fehlt und ob das überhaupt mit
UploadFile geht?
