String class for string operations

Notes:

I. C# String class for string operations: [Starts at: 00min:00sec]
string is a sequence or array of unicode characters.
Unicode is a 16 bit character set.
string class contains common properties and methods used to work with strings.

Example Code:
using UnityEngine;
public class StringDemo : MonoBehaviour {
void Start () {

string myName = "Unity Game Engine";
Debug.Log (myName); // Unity Game Engine

Debug.Log(myName.Length); // 17

Debug.Log(myName.ToUpper()); // UNITY GAME ENGINE
Debug.Log(myName.ToLower()); // unity game engine

Debug.Log(myName.StartsWith("Unity")); // True
Debug.Log(myName.EndsWith("Engine")); // True
Debug.Log(myName.Contains("C#")); // False

// -1 if given parameter comes after in the dictionary
Debug.Log(myName.CompareTo("Unity Lame Engine")); // -1

// 0 if given parameter is same
Debug.Log(myName.CompareTo("Unity Game Engine")); // 0

// 1 if given parameter comes before in the dictionary
Debug.Log(myName.CompareTo("Unity Came Engine")); // 1

Debug.Log(myName.Equals("Unity Game Engine")); // True

// strings follow 0 based indexing
// syntax: string Remove(index, # of characters to remove)
Debug.Log(myName.Remove(6,4)); // Unity Engine

Debug.Log(myName.IndexOf('U')); // 0

Debug.Log ("Sum of " + 22 + " and " + 22 + " is = " + 44);
Debug.Log (string.Format ("Sum of {0} and {1} is= {2}", 22, 22, 44));

}
}

Note:
Use Equals method to check whether 2 strings are same or not
Use CompareTo method to check the chronological order in dictionary
