Q7: You use Reflection to obtain information about a method named
MyMethod. You need to ascertain whether MyMethod is accessible to a
derived class. What should you do?
A. Call the IsAssembly property of the MethodInfo class.
B. Call the IsVirtual property of the MethodInfo class.
C. Call the IsStatic property of the MethodInfo class.
D. Call the IsFamily property of the MethodInfo class.
Answer: D
Q8: You write the following code segment to call a function from the
Win32 Application Programming Interface (API) by using platform invoke.
string personName = “N?el”;
string msg = “Welcome” + personName + “to club”!”;
bool rc = User32API.MessageBox(0, msg, personName, 0);
You need to define a method prototype that can best marshal the string
data. Which code segment should you use?
A. [DllImport("user32", CharSet = CharSet.Ansi)]
public static extern bool MessageBox(int hWnd, string text, string caption, uint type);
}
B. [DllImport("user32", EntryPoint = "MessageBoxA", CharSet = CharSet.Ansi)]
public static extern bool MessageBox(int hWnd,
[MarshalAs(UnmanagedType.LPWStr)]string text,
[MarshalAs(UnmanagedType.LPWStr)]string caption,
uint type);
}
C. [DllImport("user32", CharSet = CharSet.Unicode)]
public static extern bool MessageBox(int hWnd, string text, string caption, uint type);
}
D. [DllImport("user32", EntryPoint = "MessageBoxA", CharSet = CharSet.Unicode)]
public static extern bool MessageBox(int hWnd,
[MarshalAs(UnmanagedType.LPWStr)]string text,
[MarshalAs(UnmanagedType.LPWStr)]string caption,
uint type);
}
Answer: C
Q9: You need to create a class definition that is interoperable along with
COM. You need to ensure that COM applications can create instances of the
class and can call the GetAddress method. Which code segment should you
use?
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; }}
Answer: C
Q10: You write the following code to call a function from the Win32
Application Programming Interface (API) by using platform invoke.
int rc = MessageBox(hWnd, text, caption, type);
You need to define a methon prototype. Which code segment should you
use?
A. [DllImport("user32")]
public static extern int MessageBox(int hWnd, String text, String caption, uint type);
B. [DllImport("user32")]
public static extern int MessageBoxA(int hWnd, String text, String caption, uint type);
C. [DllImport("user32")]
public static extern int Win32API_User32_MessageBox(int hWnd, String text, String caption, uint type);
D. [DllImport(@"C:\WINDOWS\system32\user32.dll")]
public static extern int MessageBox(int hWnd, String text, String caption, uint type);
Answer: A
Q11: You need to create a dynamic assembly named MyAssembly. You also
need to save the assembly to disk. Which code segment should you use?
A. AssemblyName myAssemblyName = new AssemblyName();
myAssemblyName.Name = “MyAssembly”;
AssemblyBuilder myAssemblyBuilder = AppDomain.CurrentDomain.DefineDynamicAssembly
(myAssemblyName, AssemblyBuilderAccess.Run);
myAssemblyBuilder.Save(”MyAssembly.dll”);
B. AssemblyName myAssemblyName = new AssemblyName();
myAssemblyName.Name = “MyAssembly”;
AssemblyBuilder myAssemblyBuilder = AppDomain.CurrentDomain.DefineDynamicAssembly
(myAssemblyName, AssemblyBulderAccess.Save);
myAssemblyBuilder.Save(”MyAssembly.dll”);
C. AssemblyName myAssemblyName = new AssemblyName();
AssemblyBuilder myAssemblyBuilder = AppDomain.CurrentDomain.DefineDynamicAssembly
(myAssemblyName, AssemblyBuilderAccess.RunAndSave);
myAssemblyBuilder.Save(”MyAssembly.dll”);
D. AssemblyName myAssemblyName = new AssemblyName(”MyAssembly”);
AssemblyBuilder myAssemblyBuilder = AppDomain.CurrentDomain.DefineDynamicAssembly
(myAssemblyName, AssemblyBuilderAccess.Save);
myAssemblyBuilder.Save(”c:\\MyAssembly.dll”);
