Question

I am trying to send a project file via Gmail and i am having trouble sending the zip file with a .exe file in it. How can i change the zip file to fileName.zip.remove?

Answer 1

You can use the += operator:

string filename = "fileName.zip";
filename += ".remove";

The last line is equivalent to:

filename = filename + ".remove";

A common problem when sending e-mails is that antiviruses reject .exe files, even when they are included in zip files. You can hide the exe file in zip file if you encrypt this file. This involves giving a password to the zip file. You can write down this password in the e-mail text. The antivirus is not smart enough to use it.
