| POP3 Client as a C# Class |
| The Code Project |
| After reading Agus Kurniawan's article on using C# to communicate with a POP3 server I decided that I'd get a lot more milage if I built up a class that would act as a POP3 client. I decided to implement methods for each of the standard POP3 commands, with each method returning a string containing the response of the POP3 server (where appropriate.) In some situations the command is not valid so the methods detect this and returns an error message rather then sending the command to the server. The source code accompanying this article contains the class definitions and the demo console application (shown above) shows how to use the class to retrieve from a POP3 mail server. |
