. NET 2.0 generic quiz

When will the. NET 2.0 generic be built (construct )? When does the compiler know generic type parameters? Consider the following quiz:

Quiz 1: Write the followingCodeOutput

   Class  Program  ...  {  Static     Void  Main (  String [] ARGs)  ...  {<Int>A= NewA<Int>(); A. internalcall (12);} }    Class  A  <  T  >    ...  {  Public     Void  Internalcall (t obj) ...  {Test (OBJ );}    Public     Void  Test  <  U  >  (U obj) ...  {Console. writeline ("U");}    Public     Void  Test (  Int  OBJ) ...  {Console. writeline ("Int");}  } 

Which overload will be called? Only from the class, it seems that there is only one choice; but from the caller's perspective, there are two choices ......

Quiz 2: Write the output of the following code

   Class  Program ...  {  Static     Void  Main (  String  [] ARGs)  ... {<Int>A= NewA<Int>(); A. Test (12);}  }    Class  A  <  T >    ...  {  Public     Void  Test (t obj)  ... {Console. writeline ("T");}    Public     Void  Test (  Int  OBJ)  ... {Console. writeline ("Int");}  } 

Well ...... This is the most strange example. When you enter the code, IDE will tell you that there are two identical overload functions. Which one will you call?

Quiz 3: Write the output of the following code

   Class  Program  ...  { Static     Void  Main (  String  [] ARGs)  ... {<Int>A= NewA<Int>(); A. Test (12); A. Test (12.0);}  }    Class  A <  T  >    ...  {  Public     Void  Test  <  U  >  (U obj) ...  {Console. writeline ("U");}    Public     Void  Test (t obj) ...  {Console. writeline ("T");}  } 

After you have made these questions, you can think of the features that can be used to compileProgram?
