添加两个时间跨度的 C# 程序

TimeSpan t1 = TimeSpan.FromMinutes(1);
TimeSpan t2 = TimeSpan.FromMinutes(2);

TimeSpan res = t1.Add(t2);

Using System;
using System.Linq;
public class Demo {
   public static void Main() {
      TimeSpan t1 = TimeSpan.FromMinutes(1);
      TimeSpan t2 = TimeSpan.FromMinutes(2);
      Console.WriteLine("First TimeSpan: "+t1);
      Console.WriteLine("Second TimeSpan: "+t2);
      // Adding
      TimeSpan res = t1.Add(t2);
      Console.WriteLine("Resultant TimeSpan: "+res);
   }
}
