Hello group,

I'm just new to C# and found a code on CodeProject to pool some emails from a mail server. The code is a class so I'm adding a project and using it.

However, I get errors as:

Error      1      Using the generic type 'System.Collections.Generic.IEnumerator<T>' requires '1' type arguments      C:\downloads\WindowsFormsApplication1\Form1.cs      43      25      WindowsFormsApplication1

Error      2      'Pop3.Pop3Component' does not contain a definition for 'Body' and no extension method 'Body' accepting a first argument of type 'Pop3.Pop3Component' could be found (are you missing a using directive or an assembly reference?)      C:\downloads\WindowsFormsApplication1\Form1.cs      51      43      WindowsFormsApplication1


How can I fix them?



Thanks,
ak

This is the best solution of the your problem, you might need to change your code and use the new class.

I think it is just a matter of the missing namespace.
