C#中的DateTime.IsDaylightSavingTime()方法用于指示DateTime的此实例是否在当前时区的夏时制时间范围内。
以下是语法-
public bool IsDaylightSavingTime ();
现在让我们看一个实现DateTime.IsDaylightSavingTime()方法的示例-
using System; public class Demo { public static void Main() { DateTime d = new DateTime(2019, 10, 11, 7, 10, 40); bool res = d.IsDaylightSavingTime(); if (res) Console.WriteLine("TRUE: This instance of DateTime is within the daylight saving time range for the current time zone."); else Console.WriteLine("FALSE: This instance of DateTime is within the daylight saving time range for the current time zone."); } }
输出结果
这将产生以下输出-
FALSE: This instance of DateTime is within the daylight saving time range for the current time zone.
现在让我们来看另一个实现DateTime.IsDaylightSavingTime()方法的示例-
using System; public class Demo { public static void Main() { DateTime d = DateTime.Now; bool res = d.IsDaylightSavingTime(); if (res) Console.WriteLine("TRUE: This instance of DateTime is within the daylight saving time range for the current time zone."); else Console.WriteLine("FALSE: This instance of DateTime is within the daylight saving time range for the current time zone."); } }
输出结果
这将产生以下输出-
FALSE: This instance of DateTime is within the daylight saving time range for the current time zone.
