统计WebService的调用者、调用函数、运行时间

系统WebServic分布太久了， 都不知道哪些系统在用？ 调用的哪些函数？于是乎，写一个Soap Extension， 再加一个页面，来查询一下。

先看一下配制说明，和效果

web.config中

    <system.web>
        <compilation debug="true" targetFramework="4.0" />
      <!--<httpHandlers>
        <add path="dl" type="OA4.SOA.Impl.HttpHandler.DownloadAttach" verb="GET"/>
      </httpHandlers>-->
      <webServices>
        <soapExtensionTypes>
          <add type=" OA4.CommonLib.Soap.TimeWatchExtension,OACommonLib"
              priority="1"
              group="0" />
        </soapExtensionTypes>
      </webServices>

    </system.web>

　　

然后访问查询页面：
