你正在寫一個應(yīng)用。它利用 SOAP 去和其他應(yīng)用交換數(shù)據(jù)。你使用一個從 ArrayList 繼承的
Department 類作為數(shù)據(jù)對象發(fā)送給另一個應(yīng)用。Department 被命名為 dept。為了通過 SOAP
進(jìn)行傳送，你需要保證 Department 對象被序列化。你應(yīng)該使用下面那個代碼進(jìn)行 dept 的序列
化？
A. SoapFormatter formatter = new SoapFormatter();byte[] buffer = new
byte[dept.Capacity];MemoryStream stream = new MemoryStream(buffer); foreach
(object o in dept) {formatter.Serialize(stream, o);}
B. SoapFormatter formatter = new SoapFormatter();byte[] buffer = new
byte[dept.Capacity];MemoryStream stream = new MemoryStream(buffer);
formatter.Serialize(stream, dept);
C. SoapFormatter formatter = new SoapFormatter();MemoryStream stream = new
MemoryStream();foreach (object o in dept) {
Formatter.Serialize(stream, o);}
D. SoapFormatter formatter = new SoapFormatter();MemoryStream stream = new
MemoryStream(); formatter.Serialize(stream, dept);
答案: D

你需要寫一個完成如下任務(wù)的代碼段:
1） 查找所有暫停的服務(wù)
2） 把服務(wù)的顯示名稱增加到集合中
請問，你應(yīng)該使用那個代碼段？
A. Dim searcher As ManagementObjectSearcher = _New ManagementObjectSearcher( _
"Select * from Win32_Service where State = ’Paused’")
For Each svc As
ManagementObject In searcher.Get()
Collection1.Add(svc("DisplayName"))
Next
B. Dim searcher As ManagementObjectSearcher = _New ManagementObjectSearcher ( _
"Select * from Win32_Service", "State = ’Paused’")
For Each svc As ManagementObject In searcher.Get()
Collection1.Add(svc("DisplayName"))
Next
C. Dim searcher As ManagementObjectSearcher = _ New ManagementObjectSearcher( _
"Select * from Win32_Service")
For Each svc As ManagementObject In searcher.Get()
If svc("State").ToString() = "’Paused’" Then
Collection1.Add(svc("DisplayName"))
End If
Next
D. Dim searcher As New ManagementObjectSearcher()searcher.Scope = New
ManagementScope("Win32_Service")
For Each svc As ManagementObject In searcher.Get()
If svc("State").ToString() = "Paused" Then
Collection1.Add(svc("DisplayName"))
End If
Next
答案: A
第 18 題
你正在寫一個接收字符串參數(shù) message 的方法。你的方法必須截取 message 參數(shù)為單獨(dú)的
文本行并且傳遞每一行給另一個方法 Process。你應(yīng)該使用那個代碼段？
A. Dim reader As New
StringReader(message)ProcessMessage(reader.ReadToEnd())reader.Close()
B. Dim reader As New StringReader(message)While reader.Peek() <> -1
Dim line as String = reader.Read().ToString()
ProcessMessage(line)End Whilereader.Close()
C. Dim reader As New
StringReader(message)ProcessMessage(reader.ToString())reader.Close()
D. Dim reader As New StringReader(message)While reader.Peek() <> -1
ProcessMessage(reader.ReadLine())End Whilereader.Close()
答案: D

你需要創(chuàng)建一個能夠和 COM 進(jìn)行互操作的類。為此，你需要保證 COM 應(yīng)用能夠創(chuàng)建這個
類的實(shí)例并且能夠調(diào)用 GetAddress 方法。你應(yīng)該使用那個代碼段定義你的類？
A. public class Customer {
string addressString;
public Customer(string address) { addressString = address; }
public string GetAddress() { return addressString; }}
B. public class Customer {
static string addressString;
public Customer() { }
public static string GetAddress() { return addressString; }}
C. public class Customer {
string addressString;
public Customer() { }
public string GetAddress() { return addressString; }}
D. public class Customer {
string addressString;
public Customer() { }
internal string GetAddress() { return addressString; }}
答案: C

你正在開發(fā)一個類庫。你的代碼需要訪問系統(tǒng)環(huán)境變量。對于未給調(diào)用堆棧中處于較高位置
的所有調(diào)用方授予當(dāng)前實(shí)例所指定的權(quán)限，則在運(yùn)行時強(qiáng)制 SecurityException。你應(yīng)該調(diào)用
那個方法？
A. set.Demand();
B. set.Assert();
C. set.PermitOnly();
D. set.Deny();
