注意：
在fromework1.0和1.1是有区别的,
在1.1的 machine.config （C:/WINNT/Microsoft.NET/Framework/v1.1.4322/CONFIG）,默认webservice去除了post,get方法
你可在你的 machine.config 中加上 或者 只在 webServices 项目的 Web.config 的<system.web>里加上：
<webServices> <protocols> <add
name="
HttpPost" />
<add
name="
HttpGet" />
</protocols></webServices>
否则，在ie地址栏输入 webServices 访问地址串时，提示：
请求格式无法识别。
还有
docSubmit = new ActiveXObject("MSXML2.DOMDocument"); //1.0换成docSubmit =new ActiveXObject("Microsoft.XMLDOM"); //1.1－－－－－－－－－－－－－－－－－－－－－－－－－－
web服务方法：
[WebMethod] public string GetData(string maxval) { BaseClass.DbManagerSql dbm=new BaseClass.DbManagerSql(); string strSql="select * from s_KeShi where Keshidm>"+maxval; DataSet ds=dbm.Query(strSql); return ds.GetXml(); }
返回的xml数据：
<?xml version="1.0" encoding="utf-8" ?> <string xmlns="http://tempuri.org/"><NewDataSet> <ds> <KeShidm>6</KeShidm> <KeShimch>财务部</KeShimch> </ds> <ds> <KeShidm>7</KeShidm> <KeShimch>政工部</KeShimch> </ds><ds> <KeShidm>8</KeShidm> <KeShimch>安质部</KeShimch> </ds> <ds> <KeShidm>9</KeShidm> <KeShimch>电管部</KeShimch> </ds> <ds> <KeShidm>10</KeShidm> <KeShimch>运输公司</KeShimch> </ds> <ds> <KeShidm>11</KeShidm> <KeShimch>局长</KeShimch> </ds><ds> <KeShidm>202</KeShidm> <KeShimch>变电站</KeShimch></ds> </NewDataSet></string>
