Which of the following statements are correct about the C#.NET code snippet given below?

class Sample
{
    static int i;
    int j;
    public void proc1()
    {
        i = 11; 
        j = 22;
    }
    public static void proc2()
    {
        i = 1;
        j = 2;
    }
    static Sample()
    {
        i = 0; 
        j = 0;
    }
}

1. Sample.Length = 20;

2. Sample m = new Sample(); 
   m.Length = 10;

3. Console.WriteLine(Sample.Length);

4. Sample m = new Sample(); 
   int len;
   len = m.Length;

5. Sample m = new Sample(); 
   m.Length = m.Length + 20;

1. try blocks cannot be nested.
2. In one function, there can be only one try block.
3. An exception must be caught in the same function in which it is thrown.
4. All values set up in the exception object are available in the catch block.
5. While throwing a user-defined exception multiple values can be set in the exception, object.

interface IMyInterface 
{
    void fun1(); 
    void fun2();
}
class MyClass: IMyInterface
{ 
    private int i; 
    void IMyInterface.fun1()
    { 
        // Some code
    } 
}

int i, j = 1, k;
for (i = 0; i < 5; i++)
{
    k = j++ + ++j;
    Console.Write(k + " ");
}

1. If an exception occurs then the program terminates abruptly without getting any chance to recover from the exception.
2. No matter whether an exception occurs or not, the statements in the finally clause (if present) will get executed.
3. A program can contain multiple finally clauses.
4. A finally clause is written outside the try block.
5. finally clause is used to perform clean up operations like closing the network/database connections.

namespace CuriousTabConsoleApplication
{ 
    struct Sample
    { 
        public int i;
    }
    class MyProgram
    { 
        static void Main(string[] args)
        {
            Sample x = new Sample(); 
            x.i = 10; 
            fun(ref x); 
            Console.Write(x.i + " ");
        }
        public static void fun(ref Sample y)
        { 
            y.i = 20;
            Console.Write(y.i + " "); 
        } 
    } 
}

1. The program did not handle an exception called IndexOutOfRangeException.
2. The program execution continued after the exception occurred.
3. The exception occurred in line number 14.
4. In line number 14, the program attempted to access an array element which was beyond the bounds of the array.
5. The CLR could not handle the exception.

1. Freeing memory on the stack.
2. Avoiding memory leaks.
3. Freeing memory occupied by unreferenced objects.
4. Closing unclosed database collections.
5. Closing unclosed files.

   int[][][] intMyArr = new int[2][][];
