项目一 天气预报查询程序 测验1

1、 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

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、 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、 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：

A: 深圳 2016-09-08 多云 30 25
B:<?xml version=”1.0″?> 深圳 2016-09-08 多云 30 25
C:<?xml version=”1.0″?> 深圳 2016-09-08 多云 30 25
D: 深圳 2016-09-08 多云 30 25
答案: <?xml version=”1.0″?> 深圳 2016-09-08 多云 30 25

4、 T deserialize (String s){ XmlSerializer xml = new XmlSerializer(typeof(T)); byte[] buf = Encoding.UTF8.GetBytes(s); MemoryStream ms = new MemoryStream(buf); T obj=(T)xml.Deserialize(ms); return obj;}把字符串s反序列化成Weather对象， 那么正确的调用方法是：

A:Weather w=deserialize (s);
B:Weather w=deserialize(s);
C: Weather w=(Weather)deserialize(s);
D:都不对
答案: Weather w=deserialize (s);

5、 String serialize (T obj){ DataContractJsonSerializer json = new DataContractJsonSerializer(typeof(T)); MemoryStream ms=new MemoryStream(); json.WriteObject(ms, obj); String s=Encoding.UTF8.GetString(ms.ToArray()); return s;}而且public class Student{ public String Name {get; set; } public List Scores {get; set; }}Student s=new Student { Name=”XXX”, Scores=new List {89,90} };String t=serialize (s);结果t是

A:{“Name”:”XXX”,”Scores”:{89,90}}
B: {“Name”:”XXX”,”Scores”:[89,90]}
C: {“Name”:”XXX”,”Scores”:{“89″,”90”}}
D:{“Name”:”XXX”,”Scores”:[“89,”90”]}
答案: {“Name”:”XXX”,”Scores”:[89,90]}

6、 序列化函数String serialize (T obj){ DataContractJsonSerializer json = new DataContractJsonSerializer(typeof(T)); MemoryStream ms=new MemoryStream(); json.WriteObject(ms, obj); String s=Encoding.UTF8.GetString(ms.ToArray()); return s;}

A:正确
B:错误
答案: 正确

7、 反序列化函数T deserialize (String s) { DataContractJsonSerializer json = new DataContractJsonSerializer(typeof(T)); byte[] buf = Encoding.UTF8.GetBytes(s); MemoryStream ms = new MemoryStream(buf); T obj = (T)json.ReadObject(ms); return obj; }

A:正确
B:错误
答案: 正确

8、 序列化函数String serialize (T obj){ XmlSerializer xml = new XmlSerializer(T); MemoryStream ms=new MemoryStream(); xml.Serialize(ms, obj); String s=Encoding.UTF8.GetString(ms.ToArray()); return s;}

A:正确
B:错误
答案: 错误

9、 反序列化函数T deserialize (String s){ XmlSerializer xml = new XmlSerializer(typeof(T)); byte[] buf = Encoding.UTF8.GetBytes(s); MemoryStream ms = new MemoryStream(buf); T obj=xml.Deserialize(ms); return obj;}

A:正确
B:错误
答案: 错误

10、 反序列化函数T deserialize (String s){ XmlSerializer xml = new XmlSerializer(typeof(T)); byte[] buf = Encoding.UTF8.GetBytes(s); T obj=(T)xml.Deserialize(buf); return obj;}

A:正确
B:错误
答案: 错误

项目二 Web图片共享程序 测验2

1、 (*)public class ImageServer : IHttpHandler{ public void ProcessRequest(HttpContext context) { String uName,uPass; try { uName = context.Request.QueryString[“uName”]; uPass = context.Request.QueryString[“uPass”]; } catch (Exception exp) { } context.Response.ContentType = “text/plain”; context.Response.Write(uName+”,”+uPass); context.Response.Flush(); }}程序server.ashx部署在http://127.0.0.1/server.ashx，那么要传递uName与uPass参数，调用方法是：

A:http://127.0.0.1/server.ashx&uName=XXX&uPass=123
B:http://127.0.0.1/server.ashx?uName=XXX&uPass=123
