Question 1

What is used to validate complex string patterns like an e-mail address?
A)Required Field Validator
B)Range Validator
C)Regular Expression Validator
D)Custom Validator

Accepted Answer

Regular Expression Validator is used to validate complex string patterns, such as email addresses, by matching the input against a specified regular expression pattern.

Question 2

How many times can a constructor be called during lifetime of the object?
A)As many times as we call it.
B)Only once.
C)Any number of times before the object gets garbage collected.
D)Any number of times before the object is deleted.

Accepted Answer

A constructor is called only once in the lifetime of an object, at the time of creating the object.

Question 3

A property can be declared inside a class, struct, Interface.

Accepted Answer

In C#, properties can be declared inside a class, struct, or interface as a way to encapsulate and control access to the data.

Question 4

Which of the following statements is correct about properties used in C#.NET?
A)Every property must have a set accessor and a get accessor.
B)Properties cannot be overloaded.
C)Properties of a class are actually methods that work like data members.
D)A property has to be either read only or a write only.

Accepted Answer

Properties in C# are special methods called accessors. This includes a get accessor and optionally a set accessor, which allow properties to function like data members but with the added capability of encapsulation and special logic for getting and setting values.

Question 5

Which of the following is NOT a .NET Exception class?
A)Exception
B)StatckMemoryException
C)DivideByZeroException
D)OutofMemoryException

Accepted Answer

The correct answer is B) StatckMemoryException. This is not a recognized exception class in the .NET framework. The .NET framework includes many predefined exception classes, such as Exception, DivideByZeroException, and OutOfMemoryException, but StatckMemoryException is not one of them, likely due to a misspelling or it being a non-existent class.

Question 6

In C#.NET if we do not catch the exception thrown at runtime then which of the following will catch it?
A)Compiler
B)CLR
C)Linker
D)Loader

Accepted Answer

The Common Language Runtime (CLR) is responsible for managing the execution of .NET programs, and it catches exceptions that are not caught by the code at runtime.

Question 7

Which of the following is the Object Oriented way of handling run-time errors?
A)OnError
B)HERESULT
C)Exceptions
D)Error Codes

Accepted Answer

Exceptions are the Object-Oriented way to handle run-time errors, allowing for errors to be caught and handled in a structured and manageable manner.

Question 8

Exceptions can be thrown even from a constructor, whereas error codes cannot be returned from a constructor.

Accepted Answer

Constructors can throw exceptions to indicate failure during object creation, but they cannot return values (including error codes) because their primary purpose is to initialize an object, not to return a value.

Question 9

All code inside finally block is guaranteed to execute irrespective of whether an exception occurs in the protected block or not.

Accepted Answer

The finally block is designed to be executed after the try block. It runs regardless of whether an exception occurred in the try block or not, ensuring that the code inside the finally block is executed. Exceptions to this include scenarios where the JVM exits during the try or catch block execution or if the thread executing the try or catch block gets killed or interrupted before entering the finally block.

Question 10

It is compulsory for all classes whose objects can be thrown with throw statement to be derived from System.Exception class.

Accepted Answer

In C#, it is not compulsory for all classes whose objects are thrown with the throw statement to be derived from System.Exception. However, it is a strong convention and best practice to do so for proper exception handling. Non-Exception derived objects can technically be thrown but will not be properly handled by catch blocks expecting Exception-derived objects.

Question 11

Which of the following is NOT an Exception?
A)Stack Overflow
B)Division By Zero
C)Insufficient Memory
D)Incorrect Arithmetic Expression

Accepted Answer

Incorrect Arithmetic Expression is not classified as an Exception in most programming contexts. Exceptions like Stack Overflow, Division By Zero, and Insufficient Memory are recognized by systems or programming languages to indicate runtime errors or unusual conditions that need handling.

Question 12

Which of the following is NOT a namespace in the .NET Framework Class Library?
A)System.Process
B)System.Security
C)System.Threading
D)System.Drawing

Accepted Answer

System.Process is not a namespace in the .NET Framework Class Library. The correct namespace for working with processes is System.Diagnostics, which provides classes for working with processes, event logs, and performance counters.

Question 13

Which of the following statements is correct about a namespace in C#.NET?
A)Namespaces help us to control the visibility of the elements present in it.
B)A namespace can contain a class but not another namespace.
C)If not mentioned, then the name 'root' gets assigned to the namespace.
D)It is necessary to use the using statement to be able to use an element of a namespace.

Accepted Answer

Namespaces in C# are used to organize code and to prevent naming conflicts by grouping objects that are related under a unique name. They do not control the visibility of elements; access modifiers like public, private, etc., do that. A namespace can indeed contain other namespaces, creating a nested namespace structure. There is no default name like 'root' assigned to a namespace if not mentioned; it simply won't compile if it's not properly defined. Lastly, while the 'using' statement makes it easier to reference types within a namespace, it's not strictly necessary if you're willing to use fully qualified names.

Question 14

Which of the following CANNOT belong to a C#.NET Namespace?
A)Class
B)Struct
C)Enum
D)Data

Accepted Answer

In C#.NET, namespaces can contain definitions for classes, structs, and enums, but "Data" is not a specific type that can be defined within a namespace. Namespaces are used to organize code and can include various types like classes, structs, enums, interfaces, and delegates, but not a type specifically called "Data."

Question 15

Which of the following statements is correct about a namespace used in C#.NET?
A)Nested namespaces are not allowed.
B)Importing outer namespace imports inner namespace.
C)Nested namespaces are allowed.
D)If nested, the namespaces cannot be split across files.

Accepted Answer

Nested namespaces are allowed in C#.NET, enabling the organization of code in a hierarchical manner. This feature allows for more structured and manageable code.

Question 16

Which of the following denote the web control associated with Table control function of ASP.NET?
A)DataList
B)ListBox
C)TableRow
D)All the above

Accepted Answer

TableRow is specifically associated with the functionality of tables in ASP.NET, as it represents a row in a table.

Question 17

ASP.NET separates the HTML output from program logic using a feature named as
A)Exception
B)Code-behind
C)Code-front
D)None of the above

Accepted Answer

ASP.NET uses the Code-behind model to separate the HTML output from the program logic, allowing developers to work on the HTML and C# or VB.NET code separately.

Question 18

If a developer of ASP.NET defines style information in a common location. Then that location is called as
A)Master Page
B)Theme
C)Customization
D)None of the above

Accepted Answer

In ASP.NET, a "Theme" is used to define style information in a common location, allowing for consistent styling across multiple pages.

Question 19

The feature in ASP.NET 2.0 that is used to fire a normal postback to a different page in the application is called
A)Theme
B)Cross page posting
C)Code-front
D)None of the above

Accepted Answer

Cross page posting in ASP.NET 2.0 allows a control to post the form data to a different page. This is achieved by setting the PostBackUrl property of the control, enabling the form to be submitted to a different page from the one it was on.

Question 20

The GridView control in ASP.NET has which of the following features
A)Automatic data binding
B)Automatic paging
C)Both A and B
D)None of the above

Accepted Answer

The GridView control in ASP.NET supports both automatic data binding and automatic paging, allowing for easy display and manipulation of data from a data source.
