WebService-xml操作

将从WebService得到数据并将xml转化成Dataset显示出来

XmlDataDocument xd = new XmlDataDocument();

DataSet ds = new DataSet();

StringBuilder xmlStr = new StringBuilder(ServiceA.GetInfo(StrSearch).OuterXml);

xd.loadXml(Xml.Str.toString());

ds.readXml(new XmlNodeReader(xd));

DataGrid1.DataSource = ds.Tables['list'].DefaultView;

DataGrid1.DataBind();

引用dll的WebService方法：

1. 在IE输入服务地址：http://www.xxx.com/service.asmx

2. 然后输入：http://www.xxx.com/service.asmx?wsdl

3. 打开后，另存为xxx.wsdl

??? 用VS命令行编译：wsdl /namespace:siteA ServiceA.wsdl

??? 生成名称空间为siteA的代理类

??? 最后：css /out:ServiceA.dll /t: library Service1.cs

??? 引用dll就可以用了。
