Hello can you clarify me that can we call a base class method without creating instance?

Yes sure
Its possible If its a static method.
Its possible by inheriting from that class also.
Its possible from derived classes using base keyword

Hey guys whar are the main points of OOPS?????wannna know?????

Hi main concepts of OOPS are
1) Encapsulation: it isolates a particular code and data from all other codes and data. A well-defined interface controls the access to that particular code and data.
2) Inheritance: It is the process by which one object acquires the properties of another object. This supports the hierarchical classification,by use of inheritance, an object need only define those qualities that make it unique within its class. It can inherit its general attributes from its parent.
3) Polymorphism: It is a feature that allows one interface to be used for general class of actions. In general polymorphism means “one interface, multiple methods”, This means that it is possible to design a generic interface to a group of related activities. This helps reduce complexity by allowing the same interface to be used to specify a general class of action.

Can you tell me about MSIL??????????in Detail……..

Hi the details of MSIL are ,when compiling to managed code, the compiler translates source code into Microsoft intermediate language (MSIL), which is a CPU-independent set of instructions that can be efficiently converted to native code. MSIL includes instructions for loading, storing, initializing, and calling methods on objects, as well as instructions for arithmetic and logical operations, control flow, direct memory access, exception handling, and other operations. Microsoft intermediate language (MSIL) is a language used as the output of a number of compilers and as the input to a just-in-time (JIT) compiler. The common language runtime includes a JIT compiler for converting MSIL to native code.

What languages does the .NET Framework support?????

MS provides compilers for C#, C++, VB and JScript. Other vendors have announced that they intend to develop .NET compilers for languages such as COBOL, Eiffel, Perl, Smalltalk and Python

I’ve heard that Finalize methods should be avoided. Should I implement Finalize on my class?

Actually,An object with a Finalize method is more work for the garbage collector than an object without one. Also there are no guarantees about the order in which objects are Finalized, so there are issues surrounding access to other objects from the Finalize method. Finally, there is no guarantee that a Finalize method will get called on an object, so it should never be relied upon to do clean-up of an object’s resources.

What is CLR?? explain briefly!!!!!!!!!!!

The .NET Framework provides a runtime environment called the Common Language Runtime or CLR (similar to the Java Virtual Machine or JVM in Java), which handles the execution of code and provides useful services for the implementation of the program. CLR takes care of code management at program execution and provides various beneficial services such as memory management, thread management, security management, code verification, compilation, and other system services. The managed code that targets CLR benefits from useful features such as cross-language integration, cross-language exception handling, versioning, enhanced security, deployment support, and debugging.

Can anybody explain what is CTS??

Yes sure it describes how types are declared, used and managed in the runtime and facilitates cross-language integration, type safety, and high performance code execution

Can anybody explain what is CLS?? Please

The CLS is simply a specification that defines the rules to support language integration in such a way that programs written in any language, yet can interoperate with one another, taking full advantage of inheritance, polymorphism, exceptions, and other features

What is JIT ?????

Before Microsoft intermediate language (MSIL) can be executed, it must be converted by a .NET Framework just-in-time (JIT) compiler to native code, which is CPU-specific code that runs on the same computer architecture as the JIT compiler.
Rather than using time and memory to convert all the MSIL in a portable executable (PE) file to native code, it converts the MSIL as it is needed during execution and stores the resulting native code so that it is accessible for subsequent calls.

What is PE ?????I heard a lot of time but not clear!!!!!

HI PE is the file format defining the structure that all executable files (EXE) and Dynamic Link Libraries (DLL) must use to allow them to be loaded and executed by Windows. PE is derived from the Microsoft Common Object File Format (COFF). The EXE and DLL files created using the .NET Framework obey the PE/COFF formats and also add additional header and data sections to the files that are only used by the CLR.
