表示小时和分钟的C# int，自定义AddMinute方法

using System;

public class Program
{
    public static void Main()
    {
        int hours = 1;
        int minutes = 30;
        
        TimeSpan time = new TimeSpan(hours, minutes, 0);
        Console.WriteLine("初始时间: " + time.ToString());
        
        int additionalMinutes = 45;
        time = AddMinute(time, additionalMinutes);
        Console.WriteLine("增加分钟后的时间: " + time.ToString());
    }
    
    public static TimeSpan AddMinute(TimeSpan time, int minutes)
    {
        return time.Add(TimeSpan.FromMinutes(minutes));
    }
}
