Does C# support multiple inheritance?

  
No

C# does not support multiple inheritance. A class can inherit from maximum one base class, although it can implement any number of interfaces. Like Java, C# does not support multiple inheritance, meaning that classes cannot inherit from more than one class (More...)

Explain why java doesn't support multiple inheritance.

  
Java does not support multiple inheritances. To avoid ambiguity problem - Diamonds of Death - and complexity of multiple inheritance.

The Diamond of Death is a problem without clarity. The Diamond problem is:

Two classes Two and Three inherit from class One. Class Four inherits from both Two and Three. When a method in Four invokes a method that is defined in One, and Two and Three have overridden that method in different way, the ambiguity and complexity occurs - through which class does it inherits: class Two or class Three?

Like wise if it is encouraged to have more than two classes to inherit, the ambiguity raises which leads to future conflict of applications. (More...)

can we impliment multiple inheritance by using interfaces in C#.net?

  
yes we can implement:

Inheritance Usage Example:
Here is a syntax example for using Implementation Inheritance.


Class derivedClass:baseClass
{
}

derivedClass is derived from baseClass.

Interface Inheritance example:
private Class derivedClass:baseClass , InterfaceX , InterfaceY ....
{
}

(More...)

Can we implement Multiple Inheritance by using Abstract Class?

  
No.
As the abstarct class can contain simple methods also, therefore it doesn't support Multiple Inheritance in DotNet. (More...)

How is .NET able to support multiple languages?

  
a language should comply with the Common Language Runtime standard to become a .NET language. In .NET, code is compiled to Microsoft Intermediate Language (MSIL for short). This is called as Managed Code. This Managed code is run in .NET environment. So after compilation to this IL the language is not a barrier. A code can call or use a function written in another language. (More...)

does multiple inheritance possible in c#

  
through interfcae we can do multiple inheritance (More...)

Can code inside multiple catch block be executed?

  
No, Code can not execute in mutiple catch block (More...)

What programming languages will the .NET Framework support?

  
The .NET Framework is language neutral; virtually any language can target the .NET Framework. Currently, you can build .NET programs in a number of languages, including C++, Microsoft® Visual Basic.NET, _JScript®, and Microsoft's newest language-C#. A large number of third-party languages will also be available for building .NET Framework applications. These languages include COBOL, Eiffel, Perl, Python, Smalltalk, and others. (More...)

What is difference between interface inheritance and class inheritance?

  
We can only inherit from one class but multiple interfaces. In addition, an interface does not contain any implementation it just contains a series of signatures. (More...)

Can we have multiple threads in one App domain ?

  
One or more threads run in an AppDomain. An AppDomain is a runtime representation of a logical process within a physical process. Each AppDomain is started with a single thread, but can create additional threads from any of its threads.
Note :- All threading classes are defined in System.Threading namespace. (More...)
