Send emails with attachments with C# and Spire.Email

[string87]

I would like to send emails with attachments via C #, I downloaded spire.email and installed on the pc, I also found on the site the C # code for sending emails but debugging in visual studio I am told that the type or space name of the names "Spire" is not found, but at the beginning of the code there is "using Spire.Email", can you explain to me how Spire.Email works for sending emails with C #? Is there a tutorial?
Thanks.

Hello,

Thanks for your inquiry.

Here I prepared a sample project to show how to use Spire.Email to send messages. Please download and give it a try.
