Attachment att = new Attachment(sourceDir);
mail.Attachments.Add(att);

This is for the one file attachment .How to add all as described above as attachement in this code.. Please help me..

Answer 1

You could try something like this:

// Get all the files in the sourceDir
string[] filePaths = Directory.GetFiles(@"sourceDir");

// Get the files that their extension are either pdf of xls. 
var files = filePaths.Where(filePath => Path.GetExtension(filePath).Contains(".pdf") 
                                     || Path.GetExtension(filePath).Contains(".xls"));

// Loop through the files enumeration and attach each file in the mail.
foreach(var file in files)
{
    var attachment = new Attachment(file);
    mail.Attachments.Add(attachment);
}
