timer控件，急，跪求大神

Question

在线程里面用timer控件去触发线程，设置3秒后启动一次，为什么启动一次后，不会再触发线程了呢？不明白，求大神解救。感谢感谢

Answer 1

线程结束了，里面创建的timer就销毁了

Answer 2

timer的Elapsed事件里直接执行方法不就行了，为什么要要触发线程；代码贴出来才能帮你找原因；

Answer 3

 private void timer1_Tick(object sender, EventArgs e)
        {
            timer1.Stop();
            MessageBox.Show("1111111");
            SetLabelText st = new SetLabelText(zhuangHua);
            _thread = new Thread(new ParameterizedThreadStart(st));
            _thread.IsBackground = true;
            _thread.Start();            
        }然后在zhuangHua方法的最后面timer.Start();

Answer 4

这是我主要的代码：麻烦给我帮我看看
 private void timer1_Tick(object sender, EventArgs e)
        {
            timer1.Stop();
            MessageBox.Show("1111111");
            SetLabelText st = new SetLabelText(zhuangHua);
            _thread = new Thread(new ParameterizedThreadStart(st));
            _thread.IsBackground = true;
            _thread.Start();            
        }
        private void zhuangHua(object canshu)
        {
             string str = "0,1,2,3,4,5,6,7,8,9,a,b,c,d,e,f";
            string[] strs = str.Split(',');
            string str1 = "L00";
            string str2 = "R00000000";
            string str3 = "C00000000";            string[] folders = Directory.GetDirectories(@textBox1.Text);
            for (int i = 0; i < folders.Length; i++)
            {
                this.Invoke((EventHandler)(delegate//线程间操作无效: 从不是创建控件“listBox1”的线程访问它
                {
                    listBox1.Items.Add("级别" + i);
                }));
  
                //listBox1.Items.Add("级别" + i);
                string pathUrlone = textBox2.Text + "\\" + i;
                if (!Directory.Exists(pathUrlone))     //保证不重复 
                {
                    Directory.CreateDirectory(pathUrlone);
                }
                //listBox1.Items.Add(pathUrlone);
                string[] folders1 = Directory.GetDirectories(folders[i]);
                int j = 0;
                foreach (string s in folders1)
                {
                    string[] files = Directory.GetFiles(s);//读取文件Convert.ToInt32("CC", 16)Convert.ToString(29, 16)
                    try
                    {
                        if (Convert.ToInt32(s.Substring(s.LastIndexOf("R") + 1), 16) < Math.Pow(2, i))
                        {
                            string pathUrlbk = textBox2.Text + "\\" + i + "\\" + Convert.ToInt32(s.Substring(s.LastIndexOf("R") + 1), 16);
                            if (!Directory.Exists(pathUrlbk))     //保证不重复 
                            {
                                Directory.CreateDirectory(pathUrlbk);
                            }                            //C#遍历指定文件夹中的所有文件 
                            DirectoryInfo TheFolder = new DirectoryInfo(s);
                            foreach (FileInfo NextFile in TheFolder.GetFiles())
                            {
                                try
                                {
                                    int aa = Convert.ToInt32(NextFile.Name.Substring(1, NextFile.Name.IndexOf(".") - 1), 16);
                                    if (Convert.ToInt32(NextFile.Name.Substring(1, NextFile.Name.IndexOf(".") - 1), 16) < Math.Pow(2, i))
                                    {
                                            string pathUrlbk1 = textBox2.Text + "\\" + Convert.ToInt32(NextFile.Name.Substring(1, NextFile.Name.IndexOf(".") - 1), 16) + "\\" + Convert.ToInt32(NextFile.Name.Substring(1, NextFile.Name.IndexOf(".") - 1), 16);
                                            string strUrl = textBox2.Text + "\\" + i + "\\" + j + "\\Tile_" + j + "_" + Convert.ToInt32(NextFile.Name.Substring(1, NextFile.Name.IndexOf(".") - 1), 16) + ".JPG";
                                            //File.Delete(strUrl);
                                            File.Copy(NextFile.FullName,strUrl);
                                            // listBox1.Items.Add(Convert.ToInt32(NextFile.Name.Substring(1, NextFile.Name.IndexOf(".") - 1), 16));
                                            this.Invoke((EventHandler)(delegate
                                            {
                                                listBox1.Items.Add(NextFile.FullName + " to " + strUrl);
                                            })); 
                                           
                                    }
                                }
                                catch
                                {                                }
                            }
                        }
                    }
                    catch
                    {
                    }
                    j++;
                }
            }            timer1.Start();
        }

Answer 5

你线程本来都可以控制时间，你为什么还要那time线程去操控另一个线程？

Answer 6

用线程的sleep方法是设定时间呀，但是这里就是要求要用timer来控制，怎么解决呀？

Answer 7

已经解决了，就是在方法里面加 this.Invoke((EventHandler)(delegate//timer控件启动线程
            {
                timer1.Start();
            }));
