Hello, I am trying to use HttpWebRequest to send some POST

HttpWebRequest req = (HttpWebRequest )
WebRequest.Crea te("http://mysite.com/index.php");
req.Method = "POST";
req.ContentType = "applicatio n/x-www-form-urlencoded";
string postData = "login=value1&p wd=value2&file= filename"
req.ContentLeng th = postData.Length ;

StreamWriter stOut = new
StreamWriter(re q.GetRequestStr eam(),
System.Text.Enc oding.ASCII);
stOut.Write(pos tData);
stOut.Close();

but i am getting response Upload problem but when i am uploading file using html Form-based File Upload then file is uploading it is showing upload success.

Now then, Where exactly are you reading in the contents of the file you wish to upload and sending that? I do not see it in the code provided, it appears you do not do it at all.

i am sending name of the file in strFileName. Do i need to send byte array of the file

[Plater]

Yes, that is how it works. You need do some kinda of content disposition heading too I think which could be tricky.
I recomend searching for a quick example on the web, there should be plenty.
