当前 String 对象的值是一个小于 MinValue 或大于 MaxValue 的数字。The value of the current String object is a number less than MinValue or than MaxValue greater.

注解

此成员是显式接口成员的实现。This member is an explicit interface member implementation. 它只能在 String 实例被强制转换为 IConvertible 接口时使用。It can be used only when the String instance is cast to an IConvertible interface. 建议的替代项是调用 Convert.ToDecimal(String, IFormatProvider) 方法。The recommended alternative is to call the Convert.ToDecimal(String, IFormatProvider) method.
