Simple question about 'vbCrLf' is not declared

[Joe]

Hi,

I have a simple form that does nothing but emails the whatever user entered
in the form fields. The form is working fine and email sent. The problem I
am having is in te string that forms the body of the email. I just want to
insert line breaks using vbCrLf, but when I do that I get an error saying,

Compiler Error Message: BC30451: Name 'vbCrLf' is not declared.
The lins that gets highlighted is

objMM.Body = "First Name: " & txtFirstName.Text & vbCrLf & vbCrLf & "Last
Name: " & _

To see what I am doing, I have pasted to the code from the code behind file.
As you can see I am using VB and C#. I would appreciate if you can give me
some idea as why vbCrLf is not working.

Thanks in advance

Joe
