Sending Emails Through SMTP in C#

Recently I was looking for some code for sending emails via SMTP in C#. Below are few links which I found with some reusable code. Overall it looks fine , but have to include multiple validations for error handling .

In Nutshell, flow is as below

• Define a function to send email which accepts an input Email object
• Validate the email object to ensure all mandatory fields are present and correct
• Create a new MailMessage object and SMTPClient Object and send email

Above gist links have some reusable code to achieve step 3 of above.
