Value Type and reference type

I Searched in many websites for solution,but i am not satisfied with that answers.

Please clarify my doubt.


Why integer is valutype and why string is Reference type.

I know theoretically,int is stored in stack and string is store in heap.but i did not have clarity.

For example:

int i=10;
int j=i;
i=12;
console.writeline(i);
console.writeline(j);

O/P;
i=12;j=10;

similarly

string str1="Hello";
string str2=str1;
 str1="World";
            System.Console.WriteLine(str1);
            System.Console.WriteLine(str2);

O/p:

str1=World;
str2=Hello;

Both integer and string are same right...

class AddPrg
   {
       public String Name
       {
           get;
           set;
       }

   }

class CPrograms
   {


       static void Main()
       {

 AddPrg obg = new AddPrg();
             obg.Name = "Hello";
             AddPrg obg1 = obg;
             obg1.Name = "World";
             System.Console.WriteLine(obg1.Name);
             System.Console.WriteLine(obg.Name);


}}

O/P is World,World both are same.so that class is reference type.



Hope you understand my question.Please clarify my doubt.. Thanks in Advance...
