The code snippet below combines a dropdownlist 'ddlStates' which contains all the US States with a contact form. The snippet is simply intended to show you how to get the text value of the selected option and send it in an email.
If you were to use this as a real application then you would have to ensure all the fields were entered and a valid email address was provided using form validation.
Figure 1 shows how our file 'states.aspx' will display in your browser. The code for the file is shown below.
There are 3 textbox server controls called 'txtName' and 'txtEmail' and another textbox called 'txtMessage' with it's textmode property set to multiline. There is a button control 'Button1' and a label 'lblStatus' that doesn't have any initial text set when the page is first loaded and indeed it's visible property is set to 'false'. There is also a dropdownlist 'ddlStates'.
In short once the button 'Button1' is clicked the button's click event is raised and the subroutine Button1_Click executed. The dropdownlist's selection is assigned to the string variable 'State'.
An email is then sent with the contact form details, notice that the code below imports the 2 namespaces that we need in ASP.NET 2 to access and work with the SMTPClient and MailMessage classes and send a successful email.

The label control 'LblStatus' will display the thank you message as figure 2 below shows.
Figure 3 shows the email message that you will receive when the contact form is successfully submitted.
Just on a final note and to emphasize the fact that you should incorporate some sort of form validation.
