Question

Is it possible to override the GetHashCode method for a string, int, int32 etc..

I dont want to create a new object or class and override it that away. I wonder if there was a way to override the type’s method. Similar to an extension but not really.

string myString = "sometext";
myString.GetHashCode(); -- I want to override this method.

If you do not want to create your own class, then no because an override is only possible within a subclass.

An alternative would be to create a custom extension method like:

public static class MyExtensions
{
    public static int GetHashCode2(this string s)
    { 
         // Implementation
    }
}

This would have a similar effect, but you would need to call .GetHashCode2() rather than .GetHashCode()
