Comentarios

Cualquier instancia de UInt32, independientemente de su valor, se considera mayor que null.

El value parámetro debe ser null o una instancia de UInt32; de lo contrario, se produce una excepción.

Comentarios

Este método implementa la System.IComparable<T> interfaz y funciona ligeramente mejor que el UInt32.CompareTo método porque no tiene que convertir el value parámetro en un objeto .

En función del lenguaje de programación, es posible codificar un CompareTo método en el que el tipo de parámetro tenga menos bits (es más estrecho) que el tipo de instancia. Esto es posible porque algunos lenguajes de programación realizan una conversión de ampliación implícita que representa el parámetro como un tipo con tantos bits como la instancia.

Por ejemplo, supongamos que el tipo de instancia es Int32 y el tipo de parámetro es Byte. El compilador de C# de Microsoft genera instrucciones para representar el valor del parámetro como un Int32 objeto y, a continuación, genera un Int32.CompareTo método que compara los valores de la Int32 instancia y la representación del Int32 parámetro.

Consulte la documentación del lenguaje de programación para determinar si su compilador realiza conversiones implícitas de ampliación en tipos numéricos.
