Question about Email body in my asp.net

[JenHu]

Hi experts,

My asp.net application will send an email to our marketing department when a user filled out the application.
In my strBody of the following code, it will list all 6 strCheckBoxs (string value) from my application. If
However, how to write the lines that only when strCheckBoxs is not an empty string? I mean, skip the line if the strCheckBox is an empty string ""???

Can I use IF--ELSE statement somewhere in this code to eliminate the rows which contains empty string strCheckBox????

Thank you.
