初学,给了个描述文件,怎么创建这个web service?能帮忙写个范例么?

WebService   说明：

Service的名称统一为SpService
<wsdl:service   name="SpService">                       //这里是service的名称
        <documentation   xmlns="http://schemas.xmlsoap.org/wsdl/"   />
        <wsdl:port   name="SpServiceSoap"   binding="tns:SpServiceSoap">
            <soap:address   location="http://localhost:7000/SpService/SpService.asmx"   />
        </wsdl:port>
</wsdl:service>
取得内容信息的方法命名为GetSpServices（），无输入参数
    <wsdl:operation   name="GetSpServices">           //这里是方法的名称
            <wsdl:input   message="tns:GetSpServicesSoapIn"   />
            <wsdl:output   message="tns:GetSpServicesSoapOut"   />
        </wsdl:operation>
返回的数据类型为对象数组,对象的名称统一为ServiceInfo
    <s:element   name="GetSpServicesResponse">
                <s:complexType>
                    <s:sequence>
                      <s:element   minOccurs="0"   maxOccurs="1"   name="GetSpServicesResult"

type="tns:ArrayOfServiceInfo"   /> °     //返回的数据类型
                    </s:sequence>
                </s:complexType>
            </s:element>
            <s:complexType   name="ArrayOfServiceInfo">
                <s:sequence>
                    <s:element   minOccurs="0"   maxOccurs="unbounded"   name="ServiceInfo"   nillable="true"

type="tns:ServiceInfo"   />       数组的成员类型为ServiceInfo的对象
                </s:sequence>
            </s:complexType>
代码：
Public   ServiceInfo[]   GetSpServices()
{
ServicesInfo[]   tempServices   =   …….
…………..
Return   tempServices;
}
对象   ServiceInfo的描述如下：
            <s:complexType   name="ServiceInfo">
                <s:sequence>
                    <s:element   minOccurs="0"   maxOccurs="1"   name="TitleURL"   type="s:string"   />
                    <s:element   minOccurs="0"   maxOccurs="1"   name="TitleName"   type="s:string"   />
                    <s:element   minOccurs="0"   maxOccurs="1"   name="TitleDesc"   type="s:string"   />
                </s:sequence>
            </s:complexType>

这是我的代码   不知道怎么按照描述文件里的规则建立该web   service


  这是我上面代码调用返回的文档,大概数据结构就是这样

看看能不能访问到。
如果能的话，以后就在你写的.Net程式里去添加Web引用，这样你在所写的程式里就可以用这样的WebService撒！
我也不是特别深入了解WebService其中的奥妙，希望能对LZ有所帮助，共同进步。
