代码：

方法一：窗体的代码-->可以直接通过预设的Click事件来实现控制进度条。

public partial class Form1 : Form { public Form1() { InitializeComponent(); toolStripProgressBar_save.Minimum = 0; toolStripProgressBar_save.Maximum = 100; toolStripProgressBar_save.Step = 5; } #region 不涉及数据传输 private void button_10_Click(object sender, EventArgs e) { //清空进度表 toolStripProgressBar_save.Value = 0; if(toolStripProgressBar_save.Value<10) { for (int i=0;i<2;i++) { toolStripProgressBar_save.PerformStep(); toolStripLabel_save.Text = toolStripProgressBar_save.Value.ToString() + "%"; } } } private void button_30_Click(object sender, EventArgs e) { if (toolStripProgressBar_save.Value < 30) { for(int i=0;i<4;i++) { toolStripProgressBar_save.PerformStep(); } } toolStripLabel_save.Text = "30%"; } private void button_50_Click(object sender, EventArgs e) { if (toolStripProgressBar_save.Value < 50) { for (int i = 0; i < 4; i++) { toolStripProgressBar_save.PerformStep(); } } toolStripLabel_save.Text = "50%"; } private void button_60_Click(object sender, EventArgs e) { if (toolStripProgressBar_save.Value < 60) { for (int i = 0; i < 2; i++) { toolStripProgressBar_save.PerformStep(); } } toolStripLabel_save.Text = "60%"; } private void button_80_Click(object sender, EventArgs e) { if (toolStripProgressBar_save.Value < 80) { for (int i = 0; i < 4; i++) { toolStripProgressBar_save.PerformStep(); } } toolStripLabel_save.Text = "80%"; } private void button_100_Click(object sender, EventArgs e) { if (toolStripProgressBar_save.Value < 100) { for (int i = 0; i < 4; i++) { toolStripProgressBar_save.PerformStep(); } } toolStripLabel_save.Text = "Complete!"; } #endregion private void button_save_Click(object sender, EventArgs e) { Save.Singleton().SaveAll(); } }

方法二：通过调用其他类里的方法来实现对进度条的控制。

注意一：需要using System.Windows.Forms;

注意二：进度条ToolStripProgressBar的权限需要改成Public

public class Save { private static Save _instance = null; private Form1 n = null; public void SaveAll() { getWnd(); n.toolStripProgressBar_save.Minimum = 0; n.toolStripProgressBar_save.Maximum = 100; //清空进度表 n.toolStripProgressBar_save.Value = 0; n.toolStripProgressBar_save.Step = 5; #region 保存过程-与单独按钮是一样的 if (n.toolStripProgressBar_save.Value < 10) { for (int i = 0; i < 2; i++) { n.toolStripProgressBar_save.PerformStep(); n.toolStripLabel_save.Text = n.toolStripProgressBar_save.Value.ToString() + "%"; } } Thread.Sleep(1000); if (n.toolStripProgressBar_save.Value < 30) { for (int i = 0; i < 4; i++) { n.toolStripProgressBar_save.PerformStep(); n.toolStripLabel_save.Text = n.toolStripProgressBar_save.Value.ToString()+"%"; } } Thread.Sleep(100); if (n.toolStripProgressBar_save.Value < 50) { for (int i = 0; i < 4; i++) { n.toolStripProgressBar_save.PerformStep(); n.toolStripLabel_save.Text = n.toolStripProgressBar_save.Value.ToString() + "%"; } } Thread.Sleep(100); if (n.toolStripProgressBar_save.Value < 60) { for (int i = 0; i < 2; i++) { n.toolStripProgressBar_save.PerformStep(); n.toolStripLabel_save.Text = n.toolStripProgressBar_save.Value.ToString() + "%"; } } Thread.Sleep(100); if (n.toolStripProgressBar_save.Value < 80) { for (int i = 0; i < 4; i++) { n.toolStripProgressBar_save.PerformStep(); n.toolStripLabel_save.Text = n.toolStripProgressBar_save.Value.ToString() + "%"; } } Thread.Sleep(100); if (n.toolStripProgressBar_save.Value < 100) { for (int i = 0; i < 4; i++) { n.toolStripProgressBar_save.PerformStep(); n.toolStripLabel_save.Text = n.toolStripProgressBar_save.Value.ToString() + "%"; } } n.toolStripLabel_save.Text = "Complete!"; Thread.Sleep(100); #endregion } //查找当前打开的窗体，必须有这个才能传递数据 private void getWnd() { foreach(Form fm in Application.OpenForms) { if (fm.Name == "Form1") { n = (Form1)fm; break; } } } public static Save Singleton() { if (_instance == null) { _instance = new Save(); } return _instance; } }
