Question: You are creating a new .NET Framework application that will replace an existing unmanaged application. Although you have long-term plans to replace all unmanaged code, in the interim you need to call an unmanaged method in a COM object. How can you do this? (Choose two; each correct answer is part of a complete solution.)
A
Create an instance of the Marshal class

B
Create a prototype method for the COM function

C
Add DllImportAttribute

D
Call the Marshal.Copy method

Question: You need to call a static function in a COM object. The function is named MyFunc and is located in the MyApp.dll library. In your .NET Framework application, you want to call it using the name MyMethod. Which code sample allows you to do this?
A
<DllImport("MyApp.dll", EntryPoint := "MyFunc")> _
Public Sub MyMethod(ByVal text As String)
End Sub

B
<DllImport("MyApp.dll", EntryPoint := "MyMethod")> _
Public Sub MyFunc(ByVal text As String)
End Sub

C
<DllImport("MyApp.dll", BestFitMapping := "MyFunc")> _
Public Sub MyMethod(ByVal text As String)
End Sub

D
<DllImport("MyApp.dll", BestFitMapping := "MyMethod")> _
Public Sub MyFunc(ByVal text As String)
End Sub

Question: You need to write code equivalent to the following, but using reflection:
Dim d As New DateTime(2008, 5, 1)
Console.WriteLine(d.ToShortDateString())
Which code sample does this correctly?
A
Dim t As Type = GetType(DateTime)
Dim mi As MethodInfo = t.GetConstructor( _
New Type() {GetType(Integer), GetType(Integer), GetType(Integer)})
Dim d As Object = mi.Invoke(New Object() {2008, 5, 1})
Dim dToShortDateString As ConstructorInfo = t.GetMethod("ToShortDateString")
Console.WriteLine(DirectCast(dToShortDateString.Invoke(d, Nothing), String))

B
Dim t As Type = GetType(DateTime)
Dim ci As ConstructorInfo = t.GetConstructor(New Object() {2008, 5, 1})
Dim d As Object = ci.Invoke( _
New Type() {GetType(Integer), GetType(Integer), GetType(Integer)})
Dim dToShortDateString As MethodInfo = t.GetMethod("ToShortDateString")
Console.WriteLine(DirectCast(dToShortDateString.Invoke(d, Nothing), String))

C
Dim t As Type = GetType(DateTime)
Dim dToShortDateString As MethodInfo = t.GetMethod("ToShortDateString")
Console.WriteLine(DirectCast(dToShortDateString.Invoke(t, Nothing), String))

D
Dim t As Type = GetType(DateTime)
Dim ci As ConstructorInfo = _
t.GetConstructor(New Type() {GetType(Integer), GetType(Integer),
GetType(Integer)})
Dim d As Object = ci.Invoke(New Object() {2008, 5, 1})
Dim dToShortDateString As MethodInfo = t.GetMethod("ToShortDateString")
Console.WriteLine(DirectCast(dToShortDateString.Invoke(d, Nothing), String))
