C#中的TimeSpan.FromSeconds()方法
C#中的TimeSpan.FromSeconds()方法用于返回一个TimeSpan，该TimeSpan表示指定的秒数，其中指定的精度精确到最接近的毫秒。
语法
语法如下-
public static TimeSpan FromSeconds (double val);
上面的参数val是秒数，精确到最接近的毫秒。
示例
现在让我们看一个例子-
using System;
public class Demo {
public static void Main() {
TimeSpan span1 = TimeSpan.FromSeconds(0.6768788);
TimeSpan span2 = new TimeSpan(25, 15, 45);
TimeSpan span3 = TimeSpan.FromHours(.4788);
TimeSpan span4 = TimeSpan.FromMilliseconds(0.8787);
TimeSpan span5 = TimeSpan.FromMinutes(2.550);
Console.WriteLine("TimeSpan1 = "+span1);
Console.WriteLine("TimeSpan2 = "+span2);
Console.WriteLine("TimeSpan3 = "+span3);
Console.WriteLine("TimeSpan4 = "+span4);
Console.WriteLine("TimeSpan5 = "+span5);
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));
Console.WriteLine("Result (Comparison of span3 and span4) = "+TimeSpan.Compare(span3, span4));
Console.WriteLine("Result (Comparison of span4 and span5) = "+TimeSpan.Compare(span4, span5));
}
}输出结果
TimeSpan1 = 00:00:00.6770000 TimeSpan2 = 1.01:15:45 TimeSpan3 = 00:28:43.6800000 TimeSpan4 = 00:00:00.0010000 TimeSpan5 = 00:02:33 Result (Comparison of span1 and span2) = -1 Result (Comparison of span2 and span3) = 1 Result (Comparison of span1 and span3) = -1 Result (Comparison of span3 and span4) = 1 Result (Comparison of span4 and span5) = -1
示例
using System;
public class Demo {
public static void Main() {
TimeSpan span1 = TimeSpan.FromSeconds(1);
TimeSpan span2 = new TimeSpan(-9, 45, 50);
TimeSpan span3 = TimeSpan.FromHours(5);
TimeSpan span4 = TimeSpan.FromMilliseconds(10000);
TimeSpan span5 = TimeSpan.FromMinutes(2);
Console.WriteLine("TimeSpan1 = "+span1);
Console.WriteLine("TimeSpan2 = "+span2);
Console.WriteLine("TimeSpan3 = "+span3);
Console.WriteLine("TimeSpan4 = "+span4);
Console.WriteLine("TimeSpan5 = "+span5);
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));
Console.WriteLine("Result (Comparison of span3 and span4) = "+TimeSpan.Compare(span3, span4));
Console.WriteLine("Result (Comparison of span4 and span5) = "+TimeSpan.Compare(span4, span5));
}
}输出结果
TimeSpan1 = 00:00:01 TimeSpan2 = -08:14:10 TimeSpan3 = 05:00:00 TimeSpan4 = 00:00:10 TimeSpan5 = 00:02:00 Result (Comparison of span1 and span2) = 1 Result (Comparison of span2 and span3) = -1 Result (Comparison of span1 and span3) = -1 Result (Comparison of span3 and span4) = 1 Result (Comparison of span4 and span5) = -1
