Cero

Esta instancia es igual a value.

Un entero positivo.

Esta instancia es mayor que value.

Implementaciones

IComparable<T>.CompareTo(T)

Este método implementa la interfaz System.IComparable<T> y se ejecuta un poco mejor que el método TimeSpan.CompareTo, porque no tiene que convertir el parámetro value en objeto.

En el ejemplo de código siguiente se muestran versiones genéricas y no genéricas del método CompareTo para varios tipos de valor y de referencia.

// This example demonstrates the generic and non-generic versions of the 
// CompareTo method for several base types.
// The non-generic version takes a parameter of type Object, while the generic
// version takes a type-specific parameter, such as Boolean, Int32, or Double.
