C# CompareTo Method: Purpose and Usage

In C#, the CompareTo method is used to compare two objects. It returns an integer value representing the relationship between the current object and another object. If the current object is smaller than the other object, it returns a negative integer; if the current object is larger than the other object, it returns a positive integer; if the two objects are equal, it returns 0. The CompareTo method is commonly used for sorting or searching objects.
