Question

string a="I am comparing 2 string";
string b="I am comparing 2 string";

if(a==b)
  return true;
else
  return false;

How does a .NET compiler compare two strings? Does a string work like a struct(int)?
string is class so a=b means we are comparing 2 object, but i want to compare 2 values.

Answer 1

The String class overloads the == operator, so yes it compares the values of the strings, just like comparing value types like int.

(On a side note, the compiler also interns literal strings in the code, so the string variables a and b will actually be referencing the same string object. If you use Object.ReferenceEquals(a,b) it will also return true.)
