C#.Net recover password by email

In C#.Net 2005, the asp:PasswordRecovery control by default use User Name to recover password. But sometimes the user may forget user name, and User Email is used instead. For this we can do it this way (from here):

In aspx page:
<asp:PasswordRecovery Id="PasswordRecovery1" runat="server" OnVerifyingUser="PasswordRecovery1_VerifyingUser">
</asp:PasswordRecovery>

In Code behind:
protected void PasswordRecovery1_VerifyingUser(object sender, LoginCancelEventArgs e) {
   PasswordRecovery1.UserName = Membership.GetUserNameByEmail(PasswordRecovery1.Us erName);
}
