Answer:

==: Compares reference for reference types (unless overloaded).
Equals(): Compares value (default is reference, but can be overridden).

string a = "hello";
string b = string.Copy(a);
Console.WriteLine(a == b);       // True (content comparison for string)
Console.WriteLine(a.Equals(b));  // True

For custom types, override Equals() and GetHashCode() for value comparison.
