Question { 33514 }

What is MSIL, IL, CTS?

Answer

MSIL stands for Microsoft Intermediate Language in short
MSIL or IL(Intermediate Language). When you compile a
program the CLR will compile the code into MSIL code. which
will then be included in the assembly[exe/dll]. When you run
the program in client place. The clr will manage to convert
the MSIL into machine language by a process called Jitting.

CTS =? Common Type Specifications. A set of specifications
defined by the dotnet framework. Every type in dotnet should
comploy with CTS specifications. For example
int16,int32,int64 in C# belongs to dotnet type Int and
integers in VB.net is asso same as dotnet type Int. This
will help in Interlanguage Interoperation :) Correct me if
am wrong!!!!

Question { Microsoft, 17107 }

How do you implement multiple inheritance in .NET?

Answer

The actual answer is. We cannot provide multiple
inheritance in C#. Multiple inheritance means having a
common implementation from two base class derived in the
child class which is not possible. Using interface we just
provide the prototype which we can implement in the derived
classing which provides a mimic of multiple inheritance. If
am wrong please let me know.
