How to add condition in SSIS package to send mails only if attachments are available - ssis

Question

I have created an SSIS package that includes one script task to add new attachment name and path in a variable after "|" and running it under foreach loop to include all attachment names and path in the variable value. then I am passing that variable as an attachment to send mail task. This package is running fine via batch file execution and sending one email containing multiple files as well.
Now, I want to schedule that batch file to run on every hour, and to accomplish that, I need to add logic in the package to send mail only if 2 attachments are available. It should not send any email if there are no or single attachment present. that way I want to remove manual job execution. Can you please help? I am new to SSIS development. Script task code as below:
if (Dts.Variables["User::FileNamesList"].Value.ToString() == "")
{
Dts.Variables["User::FileNamesList"].Value = Dts.Variables["User::InputPath"].Value.ToString() + Dts.Variables["User::Year"].Value.ToString() +"\\" + Dts.Variables["User::FileName"].Value.ToString();
}
else
{
Dts.Variables["User::FileNamesList"].Value = Dts.Variables["User::FileNamesList"].Value.ToString() + "|" + Dts.Variables["User::InputPath"].Value.ToString() + Dts.Variables["User::Year"].Value.ToString() + "\\" + Dts.Variables["User::FileName"].Value.ToString();
}

Anything involving mail is much better handled in script task.
Let me explain "better". You have a lot more control on To, Cc, Bcc, ReplyTo, etc. As well as being able to send a html formatted body.
This should run your entire application:
{
var fis = Directory.GetFiles(#"C:\folder"); //a 2nd param can be added for search pattern (ex. "*.xls")
//Check for number of files
if(fis.Length>1)
{
SendEmail("Where's it going", "Here are some files", "What you want in the body", fis);
//Archive
foreach (var f in fis)
File.Move(f, #"archive folder path" + new FileInfo(f).Name);
}
}
public static void SendEmail(string to, string subject, string body, string[] filePaths)
{
string from = "SendingMail#blah.com";
using (MailMessage mail = new MailMessage())
{
SmtpClient SmtpServer = new SmtpClient("YourSMTPClient");
mail.From = new MailAddress(from);
mail.To.Add(new MailAddress(to));
mail.Subject = subject;
mail.IsBodyHtml = true;
mail.Body = body;
foreach (var f in filePaths)
{
Attachment file;
file = new Attachment(f);
mail.Attachments.Add(file);
}
SmtpServer.Port = 9999; //Your SMTP port
SmtpServer.Credentials = new NetworkCredential(from, pword);
SmtpServer.EnableSsl = true;
SmtpServer.Send(mail);
}
}

This was resolved on same day. I was able add variable in my script task to count number of files (basically it will increase by 1 on each loop execution), then I added a simple condition into arrow connecting to mail send task to first check if the variable value is matching with expected values (created a variable in SSIS and assigned max expected file count), so it now it will send mail only if 2 files are available in folder. I have added a block only just to reset the variables and that also has second arrow attached from foreach loop , to run if the condition is not matching. The tool is now sending mail only for year which will have both files present or skip for that loop. I was able to schedule that as well.
Arrow condition true: before send mail task:
condition in arrow for script task to resent variable 2:
