本文介绍如何使用C#调用WebService获取数据，并解析返回结果。同时展示了如何通过URI打开网络资源及调用Servlet服务的方法。

一、调用WEBSERVICE

    public async void getRes()
        {
            SampleDataSource ds = new SampleDataSource();
            tools.PortalRepDelegateClient proxy = new tools.PortalRepDelegateClient();
            var res = await proxy.GetRootMenuAsync();
            string tmp = res.ToString();
            string[] results = tmp.Split('#');
            for (int i = 0; i < results.Length; i++)
            {
               //
                string[] tmp2 = results[i].Split('|');
                string id = tmp2[0];
                var group6 = new SampleDataGroup("Group-"+id,
                                   tmp2[1],
                                   tmp2[2],
                                    tmp2[3],
                                  tmp2[4]);
                int itemid = Int32.Parse(id);
                var itemres = await proxy.GetGroupAsync(itemid);
                string[] itemresults = itemres.ToString().Split('|');
                for (int j = 0; j < itemresults.Length; j++)
                {
                    string[] tmp3 = itemresults[j].Split('|');
                    group6.Items.Add(new SampleDataItem("Group-"+id+"-Item-"+tmp3[0],
                            tmp3[1],
                            tmp3[2],
                            tmp3[3],
                            tmp3[4],
                            "ITEM_CONTENT",
                            group6));
                }
                ds.AllGroups.Add(group6);
            }
            //var sampleDataGroups = SampleDataSource.GetGroups((String)navigationParameter);
            this.DefaultViewModel["Groups"] = ds;// sampleDataGroups;

}

二、打开网络文件

   var selectedItem = (SampleDataItem)this.flipView.SelectedItem;
             string url = selectedItem.Subtitle;
            var uri = new Uri(url);
            var options = new Windows.System.LauncherOptions();
            options.TreatAsUntrusted = false;
            var success = await Windows.System.Launcher.LaunchUriAsync(uri, options)

三、调用SERVLET

public async static Task<string> CallServiceAsync(string serviceUrl)
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(serviceUrl);

request.Method = "Get"; // or "Post"

string result = null;
try
{
using (WebResponse response = await request.GetResponseAsync())
using (Stream responseStream = response.GetResponseStream())
using (StreamReader reader = new StreamReader(responseStream))
{
result = reader.ReadToEnd();
}
}
catch (Exception)
{ }

return result;
}
