Web Services 主要利用 HTTP 和 SOAP 协议使商业数据在 Web 上传输，SOAP通过 HTTP 调用商业对象执行远程功能调用，Web 用户能够使用 SOAP 和 HTTP通过 Web 调用的方法来调用远程对象.
web services调用存储过程简单实例：仅供学习，简单易懂！SQLHelper调用。
页面代码：

<form id="form1" runat="server">
<div>
<asp:Button ID="btnGetResponse" runat="server" Text="get response" OnClick="btnGetResponse_Click" /><br />
<asp:Label ID="lblShow" runat="server" ></asp:Label>
</div>
</form>
