我要评论webservice传xml 简单实例
传送
[webmethod]
public xmldatadocument getsiteadata(string assignname)
{
xmldatadocument xd = new xmldatadocument();
dataset ds = businesswork.businessworkdataset("treeview1");
xd = new xmldatadocument(ds);
xmlnode root1 = xd.documentelement;
xmlnodelist roots = root1.selectnodes("url");
foreach (xmlnode roota in roots) //为所有元素加上站点名称标记
{
xmlelement link = xd.createelement("sitename");
link.innertext = configurationsettings.appsettings["sitename"].tostring();
roota.appendchild(link);
}
return xd;
}
异步调用
iasyncresult ar1;
iasyncresult ar2;
localhost.webservice servicea = new localhost.webservice();
xmlnode xmlnode1;
xmlnode xmlnode2;
////直接调用
//xmlnode1 = servicea.getsiteadata("2");
//异步调用
ar1 = servicea.begingetsiteadata("3", null, null);
ar2 = servicea.begingetsiteadata("2", null, null);
xmlnode1 = servicea.endgetsiteadata(ar1);
xmlnode2 = servicea.endgetsiteadata(ar2);
stringbuilder xmlstring1;
xmlstring1 = new stringbuilder(xmlnode1.outerxml);
xmldatadocument xd = new xmldatadocument();
xd.loadxml(xmlstring1.tostring());
dataset ds = new dataset();
ds.readxml(new xmlnodereader(xd));
gridview1.datasource = ds.tables[0];
gridview1.databind();
