Judging from your description, your textbox might have an empty value.

From address is mandatory. If your txtemail.Text is empty, you will get this error. So, you should not allow the user to send the mail with out entering From address.

As the error suggest , please check what you are receiving in txtemail.Text by debugging and make sure you pass something (i.e a valid email address) as it cannot be left blank.

hope it helps :)

Why in the world you want the user to enter 'From' email address in the txtemail.Text ?? He will use it for sending email from 'any email address' . He may send a abusive email to your girlfriend using your email id in the 'From' field..

The best way is to configure the 'From' address in config file.

And the reason behind this error is that the txtemail.Text is empty..You should enter a email address in it..

The parameter 'address' cannot be an empty string. Parameter name: address ?
