What Will Be The Output Of The Following Code?

Answer»

string str1 = "Hello ";
string str2 = s1;
str1 = str1 + "C#";
System.Console.WriteLine(s2);

The output of the above code is "Hello" and not "Hello C#". This is BCOS, if you create a REFERENCE to a string, and then "modify" the original string, the reference will continue to point to the original OBJECT INSTEAD of the new object that was created when the string was modified.
