what is the purpose of "base" keyword in c# ?

Posted By :nishithraj     Posted Date :December 28, 2009    Points :10   Category :.NET Framework 
There are two uses
1) used to access a base class constructor
2) used to access a base class member in the derived class.

What is the purpose of YIELD Keyword in C#?

  
The yield keyword is used in an iterator block to provide a value to the enumerator object or to signal the end of the iteration. When used the expression is evaluated and returned as a value to the enumerator object. Note the expression has to be implicitly convertible to yield type of the iterator.

It takes one of the following forms:

yield return ;
yield break; (More...)

What is the purpose of AddHandler keyword?

  
allows you to specify an event handler
shared events or events from a structure. (More...)

What is the purpose of AddHandler keyword?

  
Addhandler associates an event with its handler at runtime. (More...)

What is the purpose of base address in WCF service? How it is specified?

  
When multiple endpoints are associated with WCF service, base address (one primary address) is assigned to the service, and relative addresses are assigned to each endpoint. Base address is specified in element for each service.
E.g.

Can we call a base class method without creating instance?

  
Its possible If its a static method.

Its possible by inheriting from that class also.

Its possible from derived classes using base keyword. (More...)

What is an orthogonal base class?

  
If two base classes have no overlapping methods or data they are said to be independent of, or orthogonal to each other. Orthogonal in the sense means that two classes operate in different dimensions and do not interfere with each other in any way. The same derived class may inherit such classes with no difficulty. (More...)

What are Abstract base classes?

  
Abstact Class is nothing but a true virtual class..
This class cannot be instantiated instead it has to be inherited.
The method in abstract class are virtual and hence they can be overriden in the child class. (More...)

Yield keyword in C Sharp

  
C Sharp and yield keyword

Hi,



One of the cool and yet most unknown feature of the C# is the yield keyword. The yield keyword is used in an iterator block to provide a value to the enumerator object or to signal the end of the iteration. When used the expression is evaluated and returned as a value to the enumerator object. Note the expression has to be implicitebly convertible to yield type of the iterator. Here is an example



public static IEnumerable GetIntCollectionFromString(string SomeString){ string[] val = SomeString.Split(' '); int intToAdd; foreach (string token in val) { if (int.TryParse(token, out intVal)) { yield return intVal; } else { yield break; } }}

Here since we are using the yield keyword the function will return the collection of intVal instead of the value of intVal. The statement will only return when the iteration of the loop is complete.



There are some limitation with the yield keywords.

Unsafe blocks are not allowed
Parameters to the method, operator, or accessor cannot be ref or out. (More...)

If any .NET language has access to everything in the Base Class Library, why is there so much talk about C#?

  
Although in theory all .NET languages have equal access to the BCL, in reality it was left up to the language teams to determine what level of support they wanted to offer, at least beyond the minimums needed for basic compliance. In our opinion, C#, because it was developed as a new language specifically for the .NET platform, has the best support for .NET applications. (More...)

What is the main purpose of having Conversation Group?

  
It's a way of grouping all the dialogs that are used for a particular task. All the dialogs associated with processing a particular order would be grouped into a single conversation group. The conversation group is implemented as a conversation group identifier, which is included with all messages in all dialogs contained in the conversation group. When a message is received from any of the dialogs in a conversation group, the conversation group is locked with a lock that is held by the receiving transaction. For the duration of the transaction, only the thread that holds the lock can receive messages from any of the dialogs in the conversation group. This makes our order entry application much easier to write because even though we use many threads for scalability, any particular order is only processed on one thread at a time. This means we don't have to make our application resilient to problems that are caused by the simultaneous processing of a single order on multiple threads. (More...)
