RegularExpressionValidator for multiple emails
asp.net, email, regex, validation
Solution
try this expression:
^(\s*,?\s*[0-9a-zA-Z]([-.\w]*[0-9a-zA-Z])*@([0-9a-zA-Z][-\w]*[0-9a-zA-Z]\.)+[a-zA-Z]{2,9})+\s*$
Problem
I'm validating a textbox for valid email with this: ``` <asp:RegularExpressionValidator ID="RegularExpressionValidator1" ControlToValidate="txtMailCustom" Text="Invalid address" ValidationExpression="^([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9] {1,3}\.)|(([a-zA-Z0-9\-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$" runat="server" /> ``` Now I want users to be able to put multiple email addresses , separated by a comma and space. How can I integrate that behaviour ?
