Decimal.IConvertible.ToInt32(IFormatProvider) 方法

定义

有关此成员的说明,请参阅 ToInt32(IFormatProvider)For a description of this member, see ToInt32(IFormatProvider).

 virtual int System.IConvertible.ToInt32(IFormatProvider ^ provider) = IConvertible::ToInt32;
int IConvertible.ToInt32 (IFormatProvider provider);
Function ToInt32 (provider As IFormatProvider) As Integer Implements IConvertible.ToInt32

参数

provider
IFormatProvider

忽略此参数。The parameter is ignored.

返回

当前实例的值,已转换为 Int32The value of the current instance, converted to a Int32.

实现

异常

生成的整数值小于 MinValue 或大于 MaxValueThe resulting integer value is less than MinValue or greater than MaxValue.

注解

此成员是显式接口成员实现。This member is an explicit interface member implementation. 它只能在 Decimal 实例被强制转换为 IConvertible 接口时使用。It can be used only when the Decimal instance is cast to an IConvertible interface. 建议的替代方法是调用 Decimal.ToInt32 方法或 Convert.ToInt32 方法。The recommended alternative is to call either the Decimal.ToInt32 method or the Convert.ToInt32 method.

Decimal 值向零舍入到最接近的整数值。The Decimal value is rounded toward zero to the nearest integer value.
