Once the proper catch code executed, the control is transferred to the finally block and then the code that follows the finally block gets executed. What is the difference between public, static and void Public declared variables or methods are accessible anywhere in the application. Static declared variables or methods are globally accessible without creating an instance of the class. Static member are by default not globally accessible it depends upon the type of access modified used.

The compiler stores the address of the method as the entry point and uses this information to begin execution before any objects are created. And Void is a type modifier that states that the method or variable does not return any value. What is an object An object is an instance of a class through which we access the methods of that class. New keyword is used to create an object. A class that creates an object in memory will contain the information about the methods, variables and behavior of that class. Define ConstructorsA constructor is a member function in a class that has the same name as its class. The constructor is automatically invoked whenever an object class is created. It constructs the values of data members while initializing the class. What is Jagged ArraysThe array which has elements of type array is called jagged array. The elements can be of different dimensions and sizes. We can also call jagged array as Array of arrays. What is the difference between ref out parameters An argument passed as ref must be initialized before passing to the method whereas out parameter needs not to be initialized before passing to a method. What is the use of using statement in CThe using block is used to obtain a resource and use it and then automatically dispose of when the execution of block completed. What is serialization When we want to transport an object through network then we have to convert the object into a stream of bytes. The process of converting an object into a stream of bytes is called Serialization. For an object to be serializable, it should implement ISerialize Interface. De serialization is the reverse process of creating an object from a stream of bytes. Can this be used within a static method We cant use This in a static method because we can only use static variablesmethods in a static method. What is difference between constants and read only Constant variables are declared and initialized at compile time. The value cant be changed afterwards. Read only is used only when we want to assign the value at run time. What is an interface classInterface is an abstract class which has only public abstract methods and the methods only have the declaration and not the definition. These abstract methods must be implemented in the inherited classes. What are value types and reference types Value types are stored in the Stack whereas reference types stored on heap. Value types. int, enum, byte, decimal, double, float, long. Reference Types. string, class, interface, object. What are Custom Control and User Control Custom Controls are controls generated as compiled code Dlls, those are easier to use and can be added to toolbox. Developers can drag and drop controls to their web forms. Attributes can be set at design time. We can easily add custom controls to Multiple Applications If Shared Dlls, If they are private then we can copy to dll to bin directory of web application and then add reference and can use them. User Controls are very much similar to ASP include files, and are easy to create. User controls cant be placed in the toolbox and dragged dropped from it. They have their design and code behind. The file extension for user controls is ascx. What are sealed classes in C We create sealed classes when we want to restrict the class to be inherited. Sealed modifier used to prevent derivation from a class. If we forcefully specify a sealed class as base class then a compile time error occurs. What is method overloadingMethod overloading is creating multiple methods with the same name with unique signatures in the same class. When we compile, the compiler uses overload resolution to determine the specific method to be invoke. What is the difference between Array and Arraylist In an array, we can have items of the same type only. The size of the array is fixed. An arraylist is similar to an array but it doesnt have a fixed size. Can a private virtual method be overridden No, because they are not accessible outside the class. Describe the accessibility modifier protected internal. Protected Internal variablesmethods are accessible within the same assembly and also from the classes that are derived from this parent class. What are the differences between System. String and System. Text. String. Builder classes System. String is immutable. When we modify the value of a string variable then a new memory is allocated to the new value and the previous memory allocation released. System. String. Builder was designed to have concept of a mutable string where a variety of operations can be performed without allocation separate memory location for the modified string. Whats the difference between the System. Array. Copy. To and System. Array. Clone Using Clone method, we creates a new array object containing all the elements in the original array and using Copy. To method, all the elements of existing array copies into another existing array. Both the methods perform a shallow copy. How can we sort the elements of the array in descending orderUsing Sort methods followed by Reverse method. Write down the C syntax to catch exception To catch an exception, we use try catch blocks. Catch block can have parameter of system. Exception type. Eg. Exception ex. tryGet. All. Data catchException exIn the above example, we can omit the parameter from catch statement. Whats the difference between an interface and abstract classInterfaces have all the methods having only declaration but no definition. In an abstract class, we can have some concrete methods. In an interface class, all the methods are public. An abstract class may have private methods. What is the difference between Finalize and Dispose methodsDispose is called when we want for an object to release any unmanaged resources with them. On the other hand Finalize is used for the same purpose but it doesnt assure the garbage collection of an object. What are circular references Circular reference is situation in which two or more resources are interdependent on each other causes the lock condition and make the resources unusable. What are generics in C.
