进度条使用

在使用进度条ProgressBar时，一般使用多线程 和 Timer 相结合。

 

比如在Form_Load中创建新的线程，用于执行你实际要的操作(比如转换文件)

 

 

 

Thread thread = new Thread(new ThreadStart(progress));

thread.Start();

 

progress()  函数中为操作内容

 

然后在Timer 的 Tick 事件中根据progress()中的进度，对进度条进行设置

 

主要代码如下：

 

private void ProgressForm_Load(object sender, EventArgs e) { progressBar_state.Minimum = 0; progressBar_state.Maximum = 100; progressBar_state.Value = 0; timer1.Enabled = true; Thread thread = new Thread(new ThreadStart(progress)); thread.Start(); } protected void progress() { DoTaskTran(); m_bTraning = false; // Sleep(1500); } private void DoTaskTran() { for (i = 0; i < m_strTaskList.Count; i++) { ////////////////////////////////////////////////////////////////////////// for (int j = 0; j < 1000000; j++) { int a = 0; } ////////////////////////////////////////////////////////////////////////// if (i == m_strTaskList.Count-1) { break; } } } private void timer1_Tick(object sender, EventArgs e) { if (m_bTraning) { button_ok.Enabled = false; this.ControlBox = false; progressBar_state.Value = i * progressBar_state.Maximum / m_strTaskList.Count; if (i == m_strTaskList.Count) { i--; } label_state.Text = "转换中..." + m_strTaskList[i].strTaskName; label_value.Text = progressBar_state.Value.ToString() + "%"; } else { progressBar_state.Value = progressBar_state.Maximum; button_ok.Enabled = true; timer1.Enabled = false; label_state.Text = "案例转换完成!"; this.Text = "完成"; label_value.Text = "100%"; this.ControlBox = true; } }
