Decimal.ToInt32(Decimal) Método

public:
 static int ToInt32(System::Decimal d);

public static int ToInt32(decimal d);

static member ToInt32 : decimal -> int

Public Shared Function ToInt32 (d As Decimal) As Integer

Entero de 32 bits con signo que equivale al valor de d.

En el ejemplo siguiente se usa el ToInt32 método para convertir números decimales en Int32 valores.

using System;

El valor devuelto es la parte integral del valor decimal; Los dígitos fraccionarios se truncan.

También puede convertir un valor en un Decimal entero de 32 bits mediante el Explicit operador de asignación. Dado que el operador realiza una conversión de restricción, debe usar un operador de conversión en C# o una función de conversión en Visual Basic.
