C#中倒計時匯總

一：

int time=0;
while(true){
Thread. Sleep(1000);
time=time+1;
Console.Write(time)
if(time>=180){
//這里放時間到了之后執行的操作，會被循環執行。
//不想循環請加break;
}
}

 

 

二：

 

Task.Factory.StartNew(() =>
                        {
                            boolTimeDown = true;
                            int time = 0;
                            while (boolTimeDown)
                            {
                                Thread.Sleep(1000);
                                time = time + 1;
                                Console.Write(time);
                                if (time <= 60)
                                {
                                    LblGetCode.Text = "剩余" + Convert.ToString(60 - time) + "秒";
                                }
                                else
                                {
                                    LblGetCode.Text = "獲取驗證碼";
                                    boolTimeDown = false;
                                    break;
                                }
                            }
                        });
