Web Services调用存储过程简单实例

转：http://www.cnblogs.com/jasenkin/archive/2010/03/02/1676634.html

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：

<body>

    <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>

</body>
