Answer 1

I was playing around DownloadFileCompleted to get the file path/file name From the event. I've tried the above solution also but It was not like my expectation then i fond the solution by adding Querystring value, Here i would like to share the code with you.

string fileIdentifier="value to remember";
WebClient webClient = new WebClient();
webClient.DownloadFileCompleted += new AsyncCompletedEventHandler (DownloadFileCompleted);
webClient.QueryString.Add("file", fileIdentifier); // here you can add values
webClient.DownloadFileAsync(new Uri((string)dyndwnldfile.path), localFilePath);

And the event can be defined as like this:

 private void DownloadFileCompleted(object sender, AsyncCompletedEventArgs e)
 {
     string fileIdentifier= ((System.Net.WebClient)(sender)).QueryString["file"];
     // process with fileIdentifier
 }
