As the name suggests, IComparable<T> reads out I’m comparable. IComparable<T> when defined for T lets you compare the current instance with another instance of same type. IComparer<T> reads out I’m a comparer, I compare. IComparer<T> is used to compare any two instances of T, typically outside the scope of the instances of T. As to … Read more
Well they are not quite the same thing as IComparer<T> is implemented on a type that is capable of comparing two different objects while IComparable<T> is implemented on types that are able to compare themselves with other instances of the same type. I tend to use IComparable<T> for times when I need to know how … Read more
All types in .NET support the Object.Equals() method which, by default, compares two types for reference equality. However, sometimes, it also desirable to be able to compare two types for structural equality. The best example of this is arrays, which with .NET 4 now implement the IStructuralEquatable interface. This makes it possible to distinguish whether … Read more
IComparable doesn’t overload the >= operator. You should use value.CompareTo(_minimumValue) >= 0
You should not define IComparable yourself. It is already defined. Rather, you need to implement IComparable on your BankAccount class. Where you defined the class BankAccount, make sure it implements the IComparable interface. Then write BankAccount.CompareTo to compare the balance amounts of the two objects. public class BankAccount : IComparable<BankAccount> { […] public int CompareTo(BankAccount … Read more
