The specified string is not in the form required for an e-mail address. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.FormatException: The specified string is not in the form required for an e-mail address.

Source Error:

Line 150: msg.From = new MailAddress("khaledaparveen11@gmail.com");

Line 151:

Line 152: msg.To.Add(new MailAddress("txtEmail.Text"));

Line 153:

msg.To.Add(new MailAddress("txtEmail.Text"));

is the problem. txtEmail.Text is not an e-mail address. If that's a text file that's a list of e-mails, you're going to need to open it and read it and pass them in one by one.

If it's referring to a textbox, take the quotes around it off. Like this:

msg.To.Add(new MailAddress(txtEmail.Text));

For me, the problem was using semi-colon(;) to seperate multiple emails. Once I change it to comma(,) it works. Hope this helps someone. share|improve this answer

This was the issue for me, thank you. – Andrew Uricchio May 2 at 16:01 up vote 2 down vote

The issue on the code above might have occured due to

msg.To.Add(new MailAddress("txtEmail.Text"));

You might be clear that here "txtEmail.Text" appears as a string but not the mailing address to whom the mail is to be send. So code should be replaced with

msg.To.Add(new MailAddress(txtEmail.Text));

and sometimes the error like "The specified string is not in the form required for an e-mail address" might also occur due to use of improper string.As even I faced it.

Basically I was working in email sending task using the ASP.Net. The main issue for me was sending mail to multiple users. Firstly, I retrieved the email address from database and used " ; " so as to separate the multiple email addresses. Because while sending the email to multiple users, in regular basis we use semicolon i.e. " ;"

Everything seemed ok but after compilation I got the error "The specified string is not in the form required for an e-mail address".

After a bit analysis, I came to know that instead of using the " ; " we should use " , " so as to separate multiple email address while sending mails . This is the formatted string for separating the emails.

Hmm, let me see, is it possible that "txtEmail.Text" is not a valid email address? I'm just guessing here, but you might want to remove the quotes from around that to get the actual value in your control... share|improve this answer

both the sender and recipient address need to be a valid email address format. eg. user@domain.com share|improve this answer

I had a problem where I was creating the message with the recipient and the sender already in it, but it returned the following error:

The specified string is not in the form required for an e-mail address

The problematic code was as follows:

MailMessage objMsg = new MailMessage(regEmail.Text.ToString(), "me@mysite.com");

I fixed the issue by replacing that code with this:

MailMessage objMsg = new MailMessage(); objMsg.From = new MailAddress(regEmail.Text.ToString()); objMsg.To.Add(new MailAddress("me@mysite.com"));

It is also helpful to use a regular expression validator in your user control to make sure the address is valid, you can use the following code for asp:

/asp:RegularExpressionValidator

Or if you'd prefer to validate the email in C# then you can use this as also stated by S Fadhel Ali:

public static bool IsValidEmail(String Email) { if( Email != null && Email != "" ) return Regex.IsMatch(Email, @"\w+([-+.]\w+)@\w+([-.]\w+).\w+([-.]\w+)*" ); else return false; }
