Sometimes due to holidays or other extreme circumstances,
we move it to another night but that is very rare. Check the home page

对了，<asp:RegularExpressionValidator ID="RegularExpressionValidator1"
Runat="server"
ErrorMessage="* You must submit a correctly formatted email address!"
ControlToValidate="TextBox3"ValidationGroup="Newsletter"
ValidationExpression="\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*">

中间得有一个空格ControlToValidate="TextBox3" ValidationGroup="Newsletter"

ControlToValidate="TextBox3" ValidationGroup="Newsletter"
