C# 问一个时间获取的问题

[智者潜行]

        Time time = new Time();
        private void timer1_Tick(object sender, EventArgs e)
        {
            time++;
            this.lblTime.Text = time.GetHours() + ":" + time.GetMinutes() + ":" + time.GetSeconds();
        }

以上代码,获得时间的格式是1:1:1
但我想获得时间的格式是:01:01:01,
就是说,单个数字时,前面加个零
请问要怎么写?

重在学习，我也来一个：

 public string Time_Format(string NDate)
        {
            string sh, sm, se;
            int hh, mm, ss;
            try
            {
                hh = Convert.ToDateTime(NDate).Hour;
                mm = Convert.ToDateTime(NDate).Minute;
                ss = Convert.ToDateTime(NDate).Second;
                
            }
            catch
            {
                return "";
            }
            sh = Convert.ToString(hh);
            if (sh.Length < 2)
                sh = "0" + sh;
            sm = Convert.ToString(mm);
            if (sm.Length < 2)
                sm = "0" + sm;
            se = Convert.ToString(ss);
            if (se.Length < 2)
                se = "0" + se;
            return sh + sm + se;
        }

这是我之前写的笨方法

            if (time.GetHours().ToString().Length == 1)
            {
                hour = "0" + time.GetHours().ToString();
            }
            else
            {
                hour =time.GetHours().ToString();
            }

            if (time.GetMinutes().ToString().Length == 1)
            {
                Minutes = "0" + time.GetMinutes().ToString();
            }
            else
            {
                Minutes =time.GetMinutes().ToString();
            }

            if (time.GetSeconds().ToString().Length == 1)
            {
                Seconds = "0" + time.GetSeconds().ToString();
            }
            else
            {
                Seconds = time.GetSeconds().ToString();
            }

time是我从网上找的的类,忘了说了,发代码,是一个记时器来的.

    class Time
    {
          private int hours;  //小时
          private int minutes; //分钟
          private int seconds; //秒钟
          
          public Time()
          {
           this.hours = 0;
           this.minutes = 0;
           this.seconds = 0;
          }

          public Time(int hours,int minutes,int seconds)
          {
           this.hours = hours;
           this.minutes = minutes;
           this.seconds = seconds;
          }

          public void SetHours(int hours)
          {
           this.hours = hours;
          }

          public void SetMinutes(int minutes)
          {
           this.minutes = minutes;
          }

          public void SetSeconds(int seconds)
          {
           this.seconds = seconds;
          }

          public int GetHours()
          {
           return this.hours;
          }

          public int GetMinutes()
          {
           return this.minutes;
          }

          public int GetSeconds()
          {
           return this.seconds;
          }

          public static Time operator ++(Time time)
          {
           time.seconds++;
           if (time.seconds >= 60)
           {
            time.minutes++;
            time.seconds = 0;
            if (time.minutes >= 60)
            {
             time.hours++;
             time.minutes = 0;
             time.seconds = 0;
             if (time.hours >= 24)
             {
              time.hours = 0;
              time.minutes = 0;
              time.seconds = 0;
             }
            }
           }
           return new Time(time.hours,time.minutes,time.seconds);
          }

                    this.timer1.Start();
                    //1000等于1秒
                    this.timer1.Interval = 1000;

这个可以用,回家就结贴

LZ用的第三方类库？

如果重写了ToString()支持格式输出的话就用time.ToString("HH:mm:ss")，如果没有就
time.GetHours().ToString("00") + ":" + time.GetMinutes.ToString("00") + ":" + time.GetSeconds.ToString("00")

[龙宜坡]

DateTime.Now.ToString("yyyy-MM-dd-hh-mm-ss")

[Jiangqincong]

time.ToString("{0:hh-mm-ss}")

[lintf1986]

24小时的用HH:mm:ss;12小时用hh:mm:ss

[zetee]

this.lblTime.Text = time.ToString("HH:mm:ss");

[jzywh]

time.ToString(":HH:mm:ss")

[楼外楼]

Time.ToString("HH:mm:ss")或"hh:mm:ss",看你需要24时还是12时的表示

[zoOoz]

请参考:

private void timer1_Tick(object sender, EventArgs e)
{
DateTime time = System.DateTime.Now;
this.lblTime.Text = time.ToString("hh:mm:ss");
}

[wangping_li]

time.ToString(":HH:mm:ss")

[智者潜行]

24小时的

[zoOoz]

Time time = new Time();
private void timer1_Tick(object sender, EventArgs e)
{
time++;
this.lblTime.Text = time.GetHours() + ":" + time.GetMinutes() + ":" + time.GetSeconds();
}
C#中没有Time类型啊,是不是楼主自定义的类,如果是自定义的类就需要在类中自己重写GetHours(),GetMinutes() 和 GetSeconds()　方法
