.net vb

  1. System .Object

  2. System .Type

  3. System .Data

Show answer
Correct Option: A

AI Explanation

To answer this question, you need to understand the inheritance hierarchy in C#.

In C#, all types are derived from the System.Object class. This means that every type supported by the Common Type System (CTS) in C# is ultimately derived from System.Object.

Let's go through each option to understand why it is correct or incorrect:

Option A) System.Object - This option is correct because all types in C# are derived from System.Object.

Option B) System.Type - This option is incorrect. While System.Type is a class in C# that represents type information, it is not the base class for all types.

Option C) System.Data - This option is incorrect. System.Data is a namespace in C# that contains classes related to data access, but it is not the base class for all types.

The correct answer is A) System.Object. This option is correct because all types in C# are derived from System.Object.

.net vb

  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
