| The Insert() function in String Class will insert a String in a specified index in the String instance. string string.Insert(int ind,string str) Parameters: ind - The index of the specified string to be inserted. str - The string to be inserted. Returns: String - The result string. Exceptions: System.ArgumentOutOfRangeException: startIndex is negative or greater than the length of this instance System.ArgumentNullException : If the argument is null. |

| 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? | |

| 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. |

| 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); |
