Can static procedures access instance data?

namespace CuriousTabConsoleApplication
{ 
    class Sample
    { 
        public int func()
        {
            return 1;
        } 
        public Single func()
        { 
            return 2.4f ;
        } 
    } 
    class Program
    { 
        static void Main(string[ ] args)
        {
            Sample s1 = new Sample(); 
            int i;
            i = s1.func(); 
            Single j; 
            j = s1.func(); 
        } 
    } 
}

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. Constructors cannot be overloaded.
2. Constructors always have the name same as the name of the class.
3. Constructors are never called explicitly.
4. Constructors never return any value.
5. Constructors allocate space for the object in memory.

1. Static functions can access only static data.
2. Static functions cannot call instance functions.
3. It is necessary to initialize static data.
4. Instance functions can call static functions and access static data.
5. this reference is passed to static functions.

int[ , ] intMyArr = {{7, 1, 3}, {2, 9, 6}};

1. intMyArr represents rectangular array of 2 rows and 3 columns.
2. intMyArr.GetUpperBound(1) will yield 2.
3. intMyArr.Length will yield 24.
4. intMyArr represents 1-D array of 5 integers.
5. intMyArr.GetUpperBound(0) will yield 2.
