AJAX和WebService实现邮箱验证(无刷新验证邮件地址是否合法)

首先在项目里面添加服务引用
—————————验证 Email 地址是否正确.aspx—————–
复制代码 代码如下:











Email<asp:Label ID="lblinfo"
runat=”server” Text=””>












——————–验证 Email 地址是否正确.aspx.cs———————–
复制代码 代码如下:
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 = “请重新验证”;
}
else if (result == 1)
{
lblinfo.Text = “邮件地址合法”;
}
else if (result == 2)
{
lblinfo.Text = “只是域名正确”;
}
else if (result == 3)
{
lblinfo.Text = “一个未知错误”;
}
else if (result == 4)
{
lblinfo.Text = “邮件服务器没有找到”;
}
else if (result == 5)
{
lblinfo.Text = “电子邮件地址错误”;
}
else if (result == 6)
{
lblinfo.Text = “免费用户验证超过数量（50次/24小时）”;
}
else if (result == 7)
{
lblinfo.Text = “商业用户不能通过验证”;
}
}
