项目一天气预报查询程序测验1

1、问题: 下面程序下载http://127.0.0.1的字符串： try { WebClient client = new WebClient(); client.Encoding = Encoding.UTF8; client.DownloadStringCompleted += client_DownloadStringCompleted; Uri uri = new Uri("http://127.0.0.1", UriKind.Absolute); client.DownloadStringAsync(uri); msg.Text = "OK"; } catch (Exception exp) { msg.Text = exp.Message; }在执行client.DownloadStringAsync(uri)后
选项：
A:程序等待服务器响应，然后显示msg.Text = "OK";
B:程序不等待服务器响应，就显示msg.Text = "OK";
C: 程序有错误，语句 client.DownloadStringCompleted += client_DownloadStringCompleted;应该为：client.DownloadStringCompleted = client_DownloadStringCompleted;
D: 以上都不对
答案: 【程序不等待服务器响应，就显示msg.Text = "OK";】

2、问题:String serialize(WeatherClass w){ ________ MemoryStream ms=new MemoryStream(); xml.Serialize(ms, w); String s=Encoding.UTF8.GetString(ms.ToArray()); return s;}序列化函数serialize缺少的语句是：

A: XmlSerializer xml = new XmlSerializer(typeof(WeatherClass));
B:XmlSerializer xml = new XmlSerializer(WeatherClass);
C:XmlSerializer xml = XmlSerializer(typeof(WeatherClass));
D:XmlSerializer xml = XmlSerializer(WeatherClass);
答案: 【 XmlSerializer xml = new XmlSerializer(typeof(WeatherClass));】

3、问题:public class WeatherItemClass{ public String description { get; set; } public double highTemp { get; set; } public double lowTemp { get; set; }}public class WeatherClass{ public String city { get; set; } public String date { get; set; } public WeatherItemClass weather { get; set; }}那么对下面的数据进行XML序列化WeatherClass wa = new WeatherClass{ city = "深圳", date = "2016-09-08", weather = new WeatherItemClass { description = "多云", lowTemp = 25, highTemp = 30 }};结果是：
选项：
A:<WeatherClass> <city>深圳</city> <date>2016-09-08</date> <weather> <description>多云</description> <highTemp>30</highTemp> <lowTemp>25</lowTemp> </weather></WeatherClass>
