How many levels of compilation happens in .NET Framework

.net vb

  1. One

  2. Two

  3. Three

Show answer
Correct Option: B

AI Explanation

To answer this question, we need to understand the compilation process in the .NET Framework.

The .NET Framework uses a two-step compilation process.

The first step is the compilation of source code into an intermediate language (IL) known as Microsoft Intermediate Language (MSIL) or Common Intermediate Language (CIL). This step is performed by the compiler, which converts the source code into IL instructions.

The second step is the Just-In-Time (JIT) compilation, which occurs at runtime. The IL code is compiled into machine code specific to the target platform. This compilation is performed by the Common Language Runtime (CLR), which is responsible for executing .NET applications.

Therefore, the correct answer is B) Two, as there are two levels of compilation in the .NET Framework.

Most of the underlying integration of .NET is done through XML

.net vb

  1. True

  2. False

Show answer
Correct Option: A

AI Explanation

To answer this question, let's go through each option to understand why it is correct or incorrect:

Option A) True - This option is correct. In the .NET framework, XML is commonly used for various purposes, including configuration files, data exchange, and serialization. XML is used extensively for integration purposes in .NET applications.

Option B) False - This option is incorrect. XML is indeed used for the underlying integration of .NET.

The correct answer is A) True. This option is correct because XML is widely used for integration in the .NET framework.

.net vb

  1. Private

  2. Protected

  3. Friend

  4. Global

Show answer
Correct Option: A
Explanation:

To answer this question, the user needs to know about access modifiers in object-oriented programming and their purpose in controlling the scope of class members.

A. Private: This option is correct. Private methods are only accessible within the class they are declared in. They cannot be accessed by other classes, even if they inherit from the same parent class.

B. Protected: This option is incorrect. Protected methods are accessible within the class they are declared in and any subclasses that inherit from the parent class. They cannot be accessed by external classes.

C. Friend: This option is incorrect. Friend methods are a C++ specific feature that allow one class to access the private members of another class. They are not available in other programming languages.

D. Global: This option is incorrect. Global methods are available to all classes and can be accessed from anywhere in the program.

Therefore, the answer is: A

How do you terminate code execute with in a VB.NET method
.net vb

  1. Exit

  2. Close Sub

  3. Exit Sub

  4. Kill

Show answer
Correct Option: C
Explanation:

To terminate code execution within a VB.NET method, you can use the "Exit Sub" statement.

Explanation of options:

A. Exit: The "Exit" keyword is used to exit a loop or block of code, but it cannot be used to terminate a method. It is not the correct option in this scenario.

B. Close Sub: This is not a valid statement in VB.NET. It is not the correct option.

C. Exit Sub: The "Exit Sub" statement is used to immediately exit from a subroutine (method) in VB.NET. It allows you to terminate the execution of the method and return control to the calling code. This is the correct option.

D. Kill: The "Kill" statement is used to delete a file in VB.NET and is not related to terminating code execution within a method. It is not the correct option.

Therefore, the correct answer is: C. Exit Sub
