How to validate Email Address in ASP.NET?

To validate Email ID in ASP.NET, set the following RegularExpressionValidator properties:

ID	Email_Validator
ControlToValidate	Email_ID
ErrorMessage	Please enter the valid Email Address.
ValidationExpression	^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,3})+$

Code Snippet:

<asp:RegularExpressionValidator ID="Email_Validator" runat="server" ControlToValidate="Email_ID" ErrorMessage="Please enter the valid Email Address" ValidationExpression="^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,3})+$"></asp:RegularExpressionValidator>

(Note: Email_ID is a TextBox ID in which email id would be entered by user).
