首先在項目里面添加服務引用
---------------------------驗證 Email 地址是否正確.aspx-----------------

復制代碼代碼如下:www.mb5u.com

 
<html xmlns="http://www.w3.org/1999/xhtml"> 
<head runat="server"> 
<title></title> 
</head> 
<body> 
<form id="form1" runat="server"> 
<asp:ScriptManager ID="ScriptManager1" runat="server"> 
</asp:ScriptManager> 
<asp:UpdatePanel ID="UpdatePanel1" runat="server"> 
<ContentTemplate> 
<div> 
Email<asp:TextBox ID="txtemail" runat="server"></asp:TextBox><asp:Label ID="lblinfo" 
runat="server" Text=""></asp:Label> 
<br /> 
<br /> 
<asp:Button ID="Button1" runat="server" Text="調用" onclick="Button1_Click" /> 
</div> 
</ContentTemplate> 
</asp:UpdatePanel> 
</form> 
</body> 
</html> 

--------------------驗證 Email 地址是否正確.aspx.cs-----------------------

復制代碼代碼如下:www.mb5u.com

 
protected void Button1_Click(object sender, EventArgs e) 
{ 
WebEmail.ValidateEmailWebService webemail = new WebEmail.ValidateEmailWebService(); 
byte result = webemail.ValidateEmailAddress(txtemail.Text); 
if (result == 0) 
{ 
lblinfo.Text = "請重新驗證"; 
} 
else if (result == 1) 
{ 
lblinfo.Text = "郵件地址合法"; 
} 
else if (result == 2) 
{ 
lblinfo.Text = "只是域名正確"; 
} 
else if (result == 3) 
{ 
lblinfo.Text = "一個未知錯誤"; 
} 
else if (result == 4) 
{ 
lblinfo.Text = "郵件服務器沒有找到"; 
} 
else if (result == 5) 
{ 
lblinfo.Text = "電子郵件地址錯誤"; 
} 
else if (result == 6) 
{ 
lblinfo.Text = "免費用戶驗證超過數量（50次/24小時）"; 
} 
else if (result == 7) 
{ 
lblinfo.Text = "商業用戶不能通過驗證"; 
} 
}
