How to add a contact to Yahoo using Oauth-2 in Asp.Net C#

I've been wrestling with this for a while now and can't seem to find a solution. The closest I've come is PHP code for Oauth-1 by Joe Chung (https://github.com/joechung/oauth_yahoo), but I can't get my head wrapped around it.
I'm using Asp.Net, and this code is in the ContactController. I have no trouble Getting contacts from Yahoo. The problem is Adding a contact to a user's Yahoo address book. The program proceeds through the Yahoo login process, and there are no errors. But the contact is not saved. I hope someone can take a look at this and tell me what I'm missing.
Thanks.

System.Net.WebException while downloading file

I have a list of mp3 which I am downloading. After some files are downloaded, not all of them - around 5-7, I get WebException. I did a stacktrace and this is the result.
Exception thrown: 'System.Net.WebException' in System.dll
Debug message: The operation has timed out
InnerEx: at System.Net.HttpWebRequest.GetResponse()
at iBlock.Main._InetGetHTMLSearch(String sArtist) in C:\Users\...\Main.cs:line 590
My _InetGetHTMLSearch looks like this
private void _InetGetHTMLSearch(string sArtist)
{
aLinks.Clear();
if (AudioDumpQuery == string.Empty)
{
//return string.Empty;
}
string[] sStringArray;
string sResearchURL = "http://www.audiodump.biz/music.html?" + AudioDumpQuery + sArtist.Replace(" ", "+");
string aRet;
HttpWebRequest webReq = (HttpWebRequest)HttpWebRequest.Create(sResearchURL);
webReq.UserAgent = "Mozilla / 5.0(Macintosh; Intel Mac OS X 10_9_3) AppleWebKit / 537.75.14(KHTML, like Gecko) Version / 7.0.3 Safari / 7046A194A";
webReq.Referer = "http://www.audiodump.com/";
webReq.Timeout = 5000;
try
{
webReq.CookieContainer = new CookieContainer();
webReq.Method = "GET";
using (WebResponse response = webReq.GetResponse())
{
using (Stream stream = response.GetResponseStream())
{
StreamReader reader = new StreamReader(stream);
aRet = reader.ReadToEnd();
//Console.WriteLine(aRet);
string[] aTable = _StringBetween(aRet, "<BR><table", "table><BR>", RegexOptions.Singleline);
if (aTable != null)
{
string[] aInfos = _StringBetween(aTable[0], ". <a href=\"", "<a href=\"");
if (aInfos != null)
{
for (int i = 0; i < aInfos.Length; i++)
{
//do some magic here
}
}
else
{
//debug
}
}
else
{
//debug 2
}
}
response.Dispose();
}
}
catch (Exception ex)
{
Console.WriteLine("Debug message: " + ex.Message + "InnerEx: " + ex.StackTrace);
aLinks.Clear();
return;
//throw exception
}
}
what this method does is simple. A simple search of the sArtist given at audiodump.com
I have a timer which runs very fast, every 10ms.
private void MainTimer_Tick(object sender, EventArgs e)
{
_DoDownload(DoubleDimList[i][y], ref mp3ToPlay);
if (muted) Mute(0);
if (Downloading)
{
StatusLabel.Text = "Downloading: " + DoubleDimList[i][y];
}
}
Now this timer handles the download in the background in a Global scope.
The _DoDownload methos which basically starts the entire process looks like this
private void _DoDownload(string dArtist, ref string dPath)
{
if (!Contain && skip <= 3 && !Downloading)
{
try
{
_InetGetHTMLSearch(dArtist);
if (aLinks.Count < 1)
{
//skip and return
Console.WriteLine("Skipping: " + dArtist);
IniWriteValue(_playlists[i], "Track " + y, dArtist + " -iBlockSkip");
y++;
return;
}
string path = mp3Path + "\\" + dArtist + ".mp3";
if (DownloadOne(aLinks[0], path, false))
{
hTimmer.Start();
Downloading = true;
}
}
catch (Exception Ex)
{
MessageBox.Show("Download start error: " + Ex.Message);
}
}
else if (Downloading)
{
try {
int actualBytes = strm.Read(barr, 0, arrSize);
fs.Write(barr, 0, actualBytes);
bytesCounter += actualBytes;
double percent = 0d;
if (fileLength > 0)
percent =
100.0d * bytesCounter /
(preloadedLength + fileLength);
label1.Text = Math.Round(percent) + "%";
if (Math.Round(percent) >= 100)
{
string path = mp3Path + "\\" + dArtist + ".mp3";
label1.Text = "";
dPath = path;
aLinks.Clear();
hTimmer.Stop();
hTimmer.Reset();
fs.Flush();
fs.Close();
lastArtistName = "N/A";
Downloading = false;
y++;
if (y >= DoubleDimList[i].Count)
{
i++;
}
}
if (Math.Round(percent) <= 1)
{
if (hTimmer.ElapsedMilliseconds >= 3000)
{
string path = mp3Path + "\\" + dArtist + ".mp3";
hTimmer.Stop();
hTimmer.Reset();
fs.Flush();
fs.Close();
System.IO.File.Delete(path);
Contain = false;
skip += 1;
Downloading = false;
}
} }
catch(Exception Ex)
{
MessageBox.Show("Downloading error: " + Ex.Message);
}
}
}
Now once the exception is thrown it messes up the entire project. As you see in the last method, if _InetGetHTMLSearch doesn't update the search(returns nothing) I am skipping and moving to next search. However the exception will be thrown in every next search. I tried setting new cookies in every search but still didn't work.
Any solutions how to avoid this issue?
P.S. I have to say that if I change the timer's Interval to 500ms it will download more mp3 before the exception is thrown but not all of them.
Edit: The issue here is obvious. The request timesout but even if I set it to Timeout.Infinite it will hand there forever

Downloading file from redirecting URLs

I am trying to download mp3 from http://www.audiodump.com/. The site has a lot of redirections. However I managed getting a part of it working.
This is my method for getting all informations such as DL links, titles, mp3 durations.

try
{
webReq.CookieContainer = new CookieContainer();
webReq.Method = "GET";
using (WebResponse response = webReq.GetResponse())
{
using (Stream stream = response.GetResponseStream())
{
StreamReader reader = new StreamReader(stream);
aRet = reader.ReadToEnd();
//Console.WriteLine(aRet);
string[] aTable = _StringBetween(aRet, "<BR><table", "table><BR>", RegexOptions.Singleline);
if (aTable != null)
{
string[] aInfos = _StringBetween(aTable[0], ". <a href=\"", "<a href=\"");
if (aInfos != null)
{
for(int i = 0; i < aInfos.Length; i++)
{

aTitles.Add(sStringArray[1]);
sStringArray[2] = sStringArray[2].Replace("`", "'");
sStringArray[2] = sStringArray[2].Replace("dont", "don't");

}
}
else

}
//return aRet;
}
}
}
catch (Exception ex)

}
I simply had to add referrer to prevent the search from redirection webReq.Referer = "http://www.audiodump.com/";
However when I want to download the mp3 I can't get it working. The urls are correct and checked with the ones I get when I download them manually rather than programmatically.

The method _DoDownload() is executed from a timer which runs every 250 milliseconds. This way works perfectly on other sites. However audiodump is giving me hard time with these redirections.
I am not a genius with httprequest. I managed solving the search issue however the download part is freaking me out. Any advice on how to manage the download issue?

You just need to set referrer to the page from where you got that download link. For example you grabbed links to files from page "http://www.audiodump.biz/music.html?q=whatever", then when downloading file set that as Referrer, not just "http://www.audiodump.biz".

Read Credentials by txt file and try login c#?

I would create a loop for function and print message in catch for all logins failed and print "sucessful connected with...." for all good logins.
Now i tried with that code, but i get only one error in textbox of catch
Button1:
if (openFileDialog1.FileName != string.Empty)
{
using (StreamReader reader = new StreamReader(openFileDialog1.FileName))
{
int count = 0;
string lineoflistemail;
while ((lineoflistemail = reader.ReadLine()) != null)
{
UserData d = new UserData();
string[] parts = lineoflistemail.Split(':');
count = parts.Length;
d.UserName = parts[0].Trim();
d.Password = parts[1].Trim();
data.Add(d);
}
foreach(UserData ud in data)
{
textBox1.Text += ("LOL" + ud.UserName + ud.Password + Environment.NewLine);
}
Second button code:
if (data.Count() == 0)
{
MessageBox.Show("Load user info first");
return;
}
for( hola = 0; hola < data.Count(); hola++)
{
var url = #"https://mail.google.com/mail/feed/atom";
var encoded = TextToBase64(data[0].UserName + ":" + data[1].Password);
var myweb = HttpWebRequest.Create(url) as HttpWebRequest;
myweb.Method = "POST";
myweb.ContentLength = 0;
myweb.Headers.Add("Authorization", "Basic " + encoded);
var response = myweb.GetResponse();
var stream = response.GetResponseStream();
textBox1.Text += ("Connection established with");
MessageBox.Show(hola.ToString());
}
}
catch (Exception ex)
{
textBox1.Text += ("Error connection. Original error: " + ex.Message);
}
}

The problem is that your try...catch is outside of your for loop. The first exception will exit the for loop, append the message to textBox1, then exit the button handler.
If you want to keep looping through even if there is an error, move the try...catch inside of the loop. Here's an example:
for( hola = 0; hola < data.Count(); hola++)
{
var url = #"https://mail.google.com/mail/feed/atom";
var encoded = TextToBase64(data[0].UserName + ":" + data[1].Password);
var myweb = HttpWebRequest.Create(url) as HttpWebRequest;
myweb.Method = "POST";
myweb.ContentLength = 0;
myweb.Headers.Add("Authorization", "Basic " + encoded);
try
{
var response = myweb.GetResponse();
var stream = response.GetResponseStream();
textBox1.Text += ("Connection established with");
MessageBox.Show(hola.ToString());
}
catch (Exception ex)
{
textBox1.Text += ("Error connection. Original error: " + ex.Message);
}
}
