try { // some code that may throw an exception } catch (Exception ex) { Console.WriteLine("Exception hash code: " + ex.GetHashCode()); }
public class CustomException : Exception { public override int GetHashCode() { return 42; // always return the same hash code } } ... try { throw new CustomException(); } catch (Exception ex) { Console.WriteLine("Exception hash code: " + ex.GetHashCode()); }In this example, we define a custom exception class that overrides GetHashCode to always return the same hash code (42). When we throw an instance of this exception and catch it, we can see that the hash code is always 42. The GetHashCode method is part of the System.Exception class, which is defined in the System.Runtime.ExceptionServices package.
