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();
