String is 1 index based thats why its start from 1.

Then why in question 2, in substring function 12 is not considered as index ?
String s1 = "ALL MEN ARE CREATED EQUAL";
String s2;
s2 = s1.Substring(12, 3);
Console.WriteLine(s2);
String s1 = "ALL MEN ARE CREATED EQUAL";
String s2;
s2 = s1.Substring(12, 3);
Console.WriteLine(s2);

If we see a String as an array of the characters then its indexing will start from 0 as it is known & it can also be considered as dynamic array.
In the rule of array 0 is the first index.
So if NAGPUR is stored in a string it will store following value at this index:
0 - N
1 - A
2 - G
3 - P
4 - U
5 - R
So if we look at line below :
s2 = s1. Insert (6, "Mumbai") ;.
It says to put the mumbai at index 6 which is a free unused space & hence instead of replacing the 'R' it stores the 'MUMBAI' after 'NAGPUR' is completed.
In the rule of array 0 is the first index.
So if NAGPUR is stored in a string it will store following value at this index:
0 - N
1 - A

According to msdn site of String.Insert() method, it says index here is zero-based, but how come can the index of a string be equal to its length?
