How to send cdo email from C#
The Microsoft .NET framework includes two namespaces, namely System.Net and System.Net.Sockets, which provide a managed implementation of Internet protocols. These namespaces allow applications to send or receive data over the Internet.
In the previous C# program, we learned how to send an email with a text body using the SMTP (Simple Mail Transfer Protocol). However, in this scenario, we are sending an email without using the SMTP protocol through C# programming. Instead of SMTP, we will be utilizing CDOSYS (Collaboration Data Objects for Windows 2000 library) for this purpose. CDOSYS is also known as Cdosys.dll, which is a library that provides functionality for sending emails.
By using the Cdosys.dll library, we can send emails directly from our C# program without relying on the SMTP protocol. This library offers a different approach to email sending and provides additional features and flexibility for customizing the email content and format.
Create a new C# project and add a reference to Microsoft CDO For Windows 2000 Library . From the following picture you can understand how to add Microsoft CDO For Windows 2000 Library in your C# project.
Exploring the CDOSYS library and understanding its usage in C# programming, you can explore alternative methods for sending emails and leverage the specific features and capabilities it offers.
