Not getting results using w3c file upload validator API

Hi,

I used following code for file upload API, but not able to get the correct
error response, pleas help:


private

static void UploadFilesToRemoteUrl(string url, string[] files, stringlogpath)

{

 long

length = 0;

string boundary = "----------------------------" +

DateTime.Now.Ticks.ToString("x");

 HttpWebRequest

httpWebRequest2 = (HttpWebRequest)WebRequest.Create(url);

httpWebRequest2.ContentType =

"multipart/form-data; boundary=" + boundary;

httpWebRequest2.Method =

"POST";

httpWebRequest2.KeepAlive =

true;

httpWebRequest2.Accept =

"text/html, application/xhtml+xml";

httpWebRequest2.Referer =

"http://validator.w3.org/";

httpWebRequest2.UserAgent =

"Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Trident/5.0)";

 httpWebRequest2.Credentials =

System.Net.

CredentialCache.DefaultCredentials;

 Stream

memStream = new System.IO.MemoryStream();

 byte

[] boundarybytes = System.Text.Encoding.ASCII.GetBytes("\r\n--" +

boundary +

"\r\n");

 memStream.Write(boundarybytes,0,boundarybytes.Length);

length += boundarybytes.Length;

string headerTemplate = "Content-Disposition: form-data; name=\"{0}\";
filename=\"{1}\"\r\n Content-Type: text/html\r\n\r\n";

 for

(int i=0;i<files.Length;i++)

{

 string

header = string.Format(headerTemplate,"file"+i,files[i]);

 byte

[] headerbytes = System.Text.Encoding.UTF8.GetBytes(header);

 memStream.Write(headerbytes,0,headerbytes.Length);

length += headerbytes.Length;

 FileStream

fileStream = new FileStream(files[i], FileMode.Open,

FileAccess.Read);

byte[] buffer = new byte[1024];

 int

bytesRead = 0;

 while

( (bytesRead = fileStream.Read(buffer, 0, buffer.Length)) != 0 )

{

memStream.Write(buffer, 0, bytesRead);

length += bytesRead;

}

 memStream.Write(boundarybytes,0,boundarybytes.Length);

length += boundarybytes.Length;

 fileStream.Close();

}

 httpWebRequest2.ContentLength = memStream.Length;

 Stream

requestStream = httpWebRequest2.GetRequestStream();

 memStream.Position = 0;

byte[] tempBuffer = new byte[memStream.Length];

memStream.Read(tempBuffer,0,tempBuffer.Length);

memStream.Close();

requestStream.Write(tempBuffer,0,tempBuffer.Length );

requestStream.Close();

 WebResponse

webResponse2 = httpWebRequest2.GetResponse();

 Stream

stream2 = webResponse2.GetResponseStream();

StreamReader reader2 = new StreamReader(stream2);

System.IO.

File.WriteAllText("test.html", reader2.ReadToEnd());

Console

..WriteLine(reader2.ReadToEnd());

 webResponse2.Close();

httpWebRequest2 =

null;

webResponse2 =

null;

 }



static void Main(string[] args)

 {

 string urlOfTool = "http://validator.w3.org/check";

 string [] fileToValidate ={ @"D:\testfile.htm"};

 UploadFilesToRemoteUrl(urlOfTool,fileToValidate,

@"D:\");

 }
