WebOf course, structs are value types, so they can't be compared by reference. There is no default implementation of == for structs because memberwise comparison isn't always a valid comparison, depending on the type. You can instead use the Object.Equals method, which does compare memberwise: Web1 day ago · Upcasting and downcasting are important concepts in C# programming that allow us to convert an object of one type to another type. These concepts are essential to work with polymorphism and object-oriented programming.
