C# decimal取整

在C#中，decimal类型可以使用Floor、Truncate和Round方法来进行取整操作。其中，Floor方法会向负无穷方向舍入为最接近的整数，而Truncate方法则会向零方向舍入为整数。另外，如果想实现四舍五入的效果，可以使用Round方法，并将小数保留到指定位数后再进行舍入操作。具体可以参考以下代码实例：

using System;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
decimal a = 8.335m, b = 8.345m;
Console.WriteLine(decimal.Floor(a)); // 8
Console.WriteLine(decimal.Truncate(b)); // 8
Console.WriteLine(decimal.Round(a, 2)); // 8.34
Console.WriteLine(decimal.Round(b, 2)); // 8.35
}
}
}

通过以上代码，可以看到在C#中使用decimal类型进行取整操作是相当简单的。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
