Which of the following can implement an interface? Data Class Enum Structure Namespace
Which of the following statements are correct about an interface in C#.NET? A class can implement multiple interfaces. Structures cannot inherit a class but can implement an interface. In C#.NET, : is used to signify that a class member implements a specific interface. An interface can implement multiple classes. The static attribute can be used with a method that implements an interface declaration.
What will be the output of the C#.NET code snippet given below? namespace IndiabixConsoleApplication { class SampleProgram { static void Main(string[ ] args) { int i, j; int[ , ] arr = new int[ 2, 2 ]; for(i = 0; i < 2; ++i) { for(j = 0; j < 2; ++j) { arr[i, j] = i * 17 + i * 17; Console.Write(arr[ i, j ] + " "); } } } } }

Which of the following is the correct output of the C#.NET code snippet given below? int[ , , ] a = new int[ 3, 2, 3 ]; Console.WriteLine(a.Length);
Which of the following statements are correct about arrays used in C#.NET? Arrays can be rectangular or jagged. Rectangular arrays have similar rows stored in adjacent memory locations. Jagged arrays do not have an access to the methods of System.Array Class. Rectangular arrays do not have an access to the methods of System.Array Class. Jagged arrays have dissimilar rows stored in non-adjacent memory locations.
Which of the following statements are correct about exception handling in C#.NET? If our program does not catch an exception then the .NET CLR catches it. It is possible to create user-defined exceptions. All types of exceptions can be caught using the Exception class. CLRExceptions is the base class for all exception classes. For every try block there must be a corresponding finally block.
Which of the following statements are correct about the exception reported below?
