Write a C# Sharp program to creates two string objects with different values. When it calls the Copy method to assign the first value to the second string, the output indicates that the strings represent different object references although their values are now equal. On the other hand, when the first string is assigned to the second string, the two strings have identical values because they represent the same object reference. 

Expected Output :

s1 = 'JAVA'                                                                      
s2 = 'Python''
