接上一页,我们先简单说明下绑定函数.首先实例化ServiceA,这个和一般类的实例化并没有不同..接下来用xmlNode1来接受函数的返回值,接下来是构造xml,并将其转化为dataset,这是通用的方法,如果是刚接触不久的朋友,最好能记下这种方法.

接下来给出异步调用两个服务的代码

    
      //绑定数据
      
      public void BindData()

{

    IAsyncResult ar1;

    IAsyncResult ar2;

    serviceA = new SiteA.Service1();

    serviceB = new SiteB.Service1();

    DataSet ds = new DataSet();

    XmlNode xmlNode1, xmlNode2;

    XmlDataDocument xd = new XmlDataDocument();

    StringBuilder xmlString1, xmlString2;

    //--简单的异步调用

    ar1 = serviceA.BeginGetSiteAData(strSearch, null, null);

    ar2 = serviceB.BeginGetSiteAData(strSearch, null, null);

    xmlNode1 = serviceA.EndGetSiteAData(ar1);

    xmlNode2 = serviceB.EndGetSiteAData(ar2);

    //----------

    if (xmlNode1 == null && xmlNode2 == null) //--存储过程执行失败

        return;

    xmlString1 = new StringBuilder(xmlNode1.OuterXml);

    xmlString2 = new StringBuilder(xmlNode2.OuterXml);

    xmlString1 = MakeNewXmlString(xmlString1, xmlString2); //生成新的xml

    if (xmlString1.ToString().Equals("<NewDataSet xmlns=\"\"></NewDataSet>"))

        return;

    xd.LoadXml(xmlString1.ToString());

    ds.ReadXml(new XmlNodeReader(xd));

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

    DataGrid1.DataBind();

}

//生成新XML
public StringBuilder MakeNewXmlString(StringBuilder str1, StringBuilder str2)

{

    str1 = str1.Replace("</NewDataSet>", "");

    str2 = str2.Replace("<NewDataSet xmlns=\"\">", "");

    str1.Append(str2.ToString());

    return str1;

}
