Compare String and Object in C#

Question

See this code:

object x = \"mehdi emrani\";
string y = \"mehdi emrani\";
Console.WriteLine(y == x);

that returns true.

Answer 1

Most probably the references are compared (standard Equals implementation for object). In the first example C# optimizes constant strings, and so y and x actually point to the same object, hence their reference is equal. In the other case, y is created dynamically, and so the reference is different.
