Solution 2

1. Split the string into array of words by space, [^]
2. The number of space will be the count of this array minus one, [^]
3. To get the item at index number i in the array, simply myArray[i], [^]

Solution 1

Try Below code:-

C#

string inputString = "My name is rohit";
string[] wordArray = inputString.Split(null); //split the string by whitespace.

//count the no. of whitespace
int countOfSpace = wordArray.Length -1;

int index = 2;
string newString = inputString.Substring(index);
string wordAfterIndex = newString.Split(null)[1]; //specify the index as to which word you want from the array.
