string type in C#.NET

First of all String is of reference type so, it is stored on the heap rather than on a stack. So whenever you assign a string variable to another string variable then it means you are creating two references of same string.

Lets take a look on following example:


/* This Example is a part of different
* examples shown in Book:
* C#2005 Beginners: A Step Ahead
* Written by: Gaurav Arora
* Reach at : gaurav.aroraose@yahoo.co.in*/


// File name : stringCS.cs

using System;

namespace CSharp.AStepAhead.stringCS
{

class stringCS
{
static void Main()
{
string str = "This is example shows the various string features ";
string str1 = "This is first String";
string str2 = "This is second String";
string str3;
Console.WriteLine("{0}\n", str);
Console.WriteLine("This is string str1 :{0}\n", str1);
Console.WriteLine("This is string str2 :{0}\n", str2);
str3 = str1 + str2;
Console.WriteLine("String Concatenation : {0}", str3);
Console.WriteLine("str1 has {0}characters", str1.Length);
str="s";
str3 = "ESS";
string res;

if (str1.Contains(str) == true)
res = "Yes";
else
res = "No";
Console.WriteLine("Does str1 contains \'{0}\':{1}", str,res);
Console.WriteLine("Str2 in upper case {0}", str2.ToUpper());
Console.WriteLine("Str1 in lower case {0}", str1.ToLower());
Console.WriteLine("In Str1 character \'{0}\' is replaced by character \'{1}\' : \nnow str1 = {2}", str,str3, str1.Replace(str, str3));

}
}
}


Hope the above tiny article elaborate the Title.
