C#: What is the difference between CompareTo(String) and Equals(String)? [duplicate]

Answer 1

The functionality in CompareTo is actually a superset of functionality of Equals. A CompareTo function dictates ordering, before, after or equals while the Equals function merely dictates equality. Hence it's actually possible to define Equals in terms of CompareTo

public bool Equals(string other) {
  return 0 == CompareTo(other);
}
