Biztalk 2010 handling exception using the scope in Orchestration.

Question

Hello,
1. I am trying to handle the errors and put them in the log using Scope. Here is the Orchestration I used,
The Expression_1 has
System.Diagnostics.EventLog.WriteEntry("Message Sent to the destination", "Message Sent to the destination");
Expression_2 has
System.Diagnostics.EventLog.WriteEntry("Failed to send the message to destination", "Failed to send the message to destination --" + exception.ToString() );
Expression_3 has
System.Diagnostics.EventLog.WriteEntry("General Exception-- Failed to send the message to destination", "Caught GeneralException-- Failed to send the message to destination");
When the message is sent without errors it shows up in the log. The message with error doesnot show up I dont know why,
I don't know what has to be changed.
2. I also don't know how to construct the error message and send it through email without using ESB toolkit. Any help is greatly appreciated. Thanks

Answer 1

Not sure I understand your first question. Is it "how to create and test an error (hence an error handling)?" If so, the easiest way is to add an Throw exception shape and set up the exception you are going to catch in the exception catch block.
2. you can use just the plain C# code like this:
MailMessage mail = new MailMessage("[email protected]", "[email protected]");
SmtpClient client = new SmtpClient();
client.Port = 25;
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.UseDefaultCredentials = false;
client.Host = "smtp.google.com";
mail.Subject = "this is a test email.";
mail.Body = "this is my test email body";
client.Send(mail);
copied from
here. It uses
System.Net.SmtpClient class.
