To answer this question, the user should be familiar with the concept of typed datasets and their relationship to other classes in the .NET framework.
The correct answer is:
In the .NET framework, the base class for typed datasets is the Dataset class. A typed dataset is a dataset that is derived from the Dataset class and includes additional features such as strongly-typed data tables and data columns.
A. DataReader is not the base class for TypedDataset. The DataReader class is used for reading data from a database and does not have a direct relationship to typed datasets.
C. DataAdapter is also not the base class for TypedDataset. The DataAdapter class is used for retrieving and updating data from a database, but it is not the base class for typed datasets.
Therefore, the correct answer is B. Dataset.
To refer to the current class in VB.Net, you would use the "Me" keyword.
A. Me: This option is correct. In VB.Net, "Me" is a keyword that represents the current instance of the class. It can be used to access the members and properties of the current class.
B. This: This option is incorrect. In VB.Net, "This" is not used to refer to the current class. Instead, "This" is used in other programming languages like C# to refer to the current instance of a class.
C. Super: This option is incorrect. In VB.Net, "Super" is not used to refer to the current class. Instead, "Super" is used in other programming languages like Java to refer to the superclass or base class.
The Answer is: A. Me
To refer to the parent class in VB.Net, we use the keyword "MyBase". Therefore, the correct answer is:
The Answer is: B. MyBase
The serialization of an Object means that it is written out to a stream
To solve this question, the user needs to have knowledge about the Debug class and its methods.
The Debug class is a class in C# that provides a set of methods, properties, and events to assist in debugging applications. It is mainly used for debugging purposes, such as tracing, logging, and error handling.
Now, let's go through each option and explain why it is right or wrong:
A. Assert( ): This is a method of the Debug class, which is used to check whether a condition is true or false. If the condition is false, it will stop the execution of the program and display an error message. Therefore, option A is not the correct answer.
B. Open(): This method is not a part of the Debug class. It is a method of the File class, which is used to open a file in the specified mode. Therefore, option B is the correct answer.
C. Flush( ): This is a method of the Debug class, which is used to clear the output buffer and send any pending messages to the listeners. Therefore, option C is not the correct answer.
The Answer is: B
