Description

GetHashCode is a generic method used to generate a hash code for a value.

Use GetHashCode to generate a hash code for the given input value. Any class that descends from TEqualityComparer is expected to implement the GetHashCode method.

Note: The generated hash codes are not required to be unique. Still, we recommend that the generated values are as different as possible from one another. Two equal values are required to have the same hash code, while two different values are not required to have different hash codes.
