WebService应用程序的文件配置app.config内容如下：<?xmlversion="1.0"encoding="utf-8"?><appSettings>
<addkey="storeDirectory"value="dataPath"/></appSettings>
"storeDirectory"值为设定的资料列表文件存储目录，可
根据实际需求修改。
3前台异步接收服务器返回的XML
前台AJax程序调用后台服务器中的WebService，调用完
毕后，利用XMLHTTP对象提供了onreadyStateChange事件进行异步响应。
functionListPlanInfo(folderNameTxt,fileName){
if(fileName==null){fileName="";}
varserverUrl="http://localhost/dz_webServer/Web-Service.asmx/";
varxmlhttp=newActiveXObject("Microsoft.XML-HTTP");
