Is it possible to change the const keyword object?

Posted By :Narayanan     Posted Date :July 30, 2012    Points :40   Category :C# 
No, you will get this error "The left-hand side of an assignment must be a variable, property or indexer".

You can also find related Interview Question to Is it possible to change the const keyword object?  below: 

What is a Null object?

It is an object of some class whose purpose is to indicate that a real object of that class does not exist. One common use for a null object is a return value from a member function that is supposed to return an object with some specified properties but cannot find such an object. (More...)

What is Object Oriented model?

This model is based on collection of objects. An object contains values stored in instance variables with in the object. An object also contains bodies of code that operate on the object. These bodies of code are called methods. Objects that contain same types of values and the same methods are grouped together into classes. (More...)

Yield keyword in C Sharp

C Sharp and yield keyword


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...)

How can we change priority and what the levels of priority are provided by .NET ?

Thread Priority can be changed by using Threadname.Priority = ThreadPriority.Highest. In the sample provided look out for code where the second thread is ran with a high priority.
Following are different levels of Priority provided by .NET :-
. ThreadPriority.Highest
. ThreadPriority.AboveNormal
. ThreadPriority.Normal
. ThreadPriority.BelowNormal
. ThreadPriority.Lowest (More...)

How can I look up a parent class method or property of any System-level object?

Use the Class View window, accessed from the standard toolbar by clicking View | Class View. (More...)

What is object Reference Tracing?

Object Reference Tracing is record sequential stack traces each time whenever object reference counter is incremented or decremented. These traces help to detect object reference errors, double-dereferencing, failure to reference. (More...)

Does SessionID change with every request in the asp.net 2.0 application?

For any web programmer, its obvious to think and believe that SessionId remains same through out the user session and it was right till asp.net1.1. But in asp.net2.0, this behavior has changed. In the asp.net application new sessionid is returned with the response to every request until session objects are not used.

According to MSDN the reason/solution is:

"When using cookie-based session state, ASP.NET does not allocate storage for session data until the Session object is used. As a result, a new session ID is generated for each page request until the session object is accessed. If your application requires a static session ID for the entire session, you can either implement the Session_Start method in the application's Global.asax file and store data in the Session object to fix the session ID, or you can use code in another part of your application to explicitly store data in the Session object."

Enjoy. (More...)
