C#中的TimeSpan.FromMinutes()方法
C#中的TimeSpan.FromMinutes()方法用于返回一个TimeSpan，该TimeSpan表示指定的分钟数，其中指定的精确度精确到最近的毫秒。
语法
public static TimeSpan FromMinutes (double val);
在上面，值val是分钟数，精确到最接近的毫秒。
示例
using System;
public class Demo {
public static void Main() {
TimeSpan span1 = TimeSpan.FromHours(0.78787);
TimeSpan span2 = new TimeSpan(10, 30, 40);
TimeSpan span3 = TimeSpan.FromHours(5);
TimeSpan span4 = TimeSpan.FromMilliseconds(1);
TimeSpan span5 = TimeSpan.FromMinutes(100);
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 = 00:47:16.3320000 TimeSpan2 = 10:30:40 TimeSpan3 = 05:00:00 TimeSpan4 = 00:00:00.0010000 TimeSpan5 = 01:40:00 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
示例
using System;
public class Demo {
public static void Main() {
TimeSpan span1 = TimeSpan.FromMinutes(200);
TimeSpan span2 = new TimeSpan(20, 10, 15);
TimeSpan span3 = TimeSpan.FromHours(.78);
TimeSpan span4 = TimeSpan.FromMilliseconds(1);
TimeSpan span5 = TimeSpan.FromMinutes(150);
Console.WriteLine("TimeSpan1 = "+span1);
Console.WriteLine("TimeSpan2 = "+span2);
Console.WriteLine("TimeSpan3 = "+span3);
Console.WriteLine("TimeSpan4 = "+span4);
Console.WriteLine("TimeSpan5 = "+span5);

}
}输出结果
