C# 中的 TimeSpan.FromHours() 方法用于返回一个 TimeSpan，该 TimeSpan 表示指定的小时数，其精确到毫秒。
语法
语法如下 −
public static TimeSpan FromHours (double val);
以上，值 val 是精确到毫秒的小时数。
示例
现在让我们看一个例子−
using System;
public class Demo {
public static void Main(){
TimeSpan span1 = TimeSpan.FromDays(0.000323456);
TimeSpan span2 = new TimeSpan(-2, 05, 10);
TimeSpan span3 = TimeSpan.FromHours(5);
Console.WriteLine("TimeSpan1 = "+span1);
Console.WriteLine("TimeSpan2 = "+span2);
Console.WriteLine("TimeSpan3 = "+span3);
Console.WriteLine("Result (Comparison of span1 and span2) = "+TimeSpan.Compare(span1, span2));
Console.WriteLine("Result (Comparison of span2 and span3) = "+TimeSpan.Compare(span2, span3));
}
}
输出
这将产生以下输出 −
TimeSpan1 = 00:00:27.9470000 TimeSpan2 = -01:54:50 TimeSpan3 = 05:00:00 Result (Comparison of span1 and span2) = 1 Result (Comparison of span2 and span3) = -1
示例
现在让我们看另一个例子 −
using System;
public class Demo {
public static void Main(){
TimeSpan span1 = TimeSpan.FromDays(15);
TimeSpan span2 = new TimeSpan(5, 15, 30);
TimeSpan span3 = TimeSpan.FromHours(5);
Console.WriteLine("TimeSpan1 = "+span1);
Console.WriteLine("TimeSpan2 = "+span2);
Console.WriteLine("TimeSpan3 = "+span3);
Console.WriteLine("Result (Comparison of span1 and span2) = "+TimeSpan.Compare(span1, span2));
Console.WriteLine("Result (Comparison of span2 and span3) = "+TimeSpan.Compare(span2, span3));
Console.WriteLine("Result (Comparison of span1 and span3) = "+TimeSpan.Compare(span1, span3));
}
}
输出
这将产生以下输出 −
TimeSpan1 = 15.00:00:00 TimeSpan2 = 05:15:30 TimeSpan3 = 05:00:00 Result (Comparison of span1 and span2) = 1 Result (Comparison of span2 and span3) = 1 Result (Comparison of span1 and span3) = 1
