C#学习笔记-数据的传递以及ToolStripProgressBar

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 = ;
             toolStripProgressBar_save.Maximum = ;
             toolStripProgressBar_save.Step = ;
         }         #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 = ;             if(toolStripProgressBar_save.Value<)
             {
                 for (int i=;i<;i++)
                 {
                     toolStripProgressBar_save.PerformStep();
                     toolStripLabel_save.Text = toolStripProgressBar_save.Value.ToString() + "%";
                 }
             }
         }         private void button_30_Click(object sender, EventArgs e)
         {
             if (toolStripProgressBar_save.Value < )
             {
                 for(int i=;i<;i++)
                 {
                     toolStripProgressBar_save.PerformStep();
                 }
             }
             toolStripLabel_save.Text = "30%";
         }         private void button_50_Click(object sender, EventArgs e)
         {
             if (toolStripProgressBar_save.Value < )
             {
                 for (int i = ; i < ; i++)
                 {
                     toolStripProgressBar_save.PerformStep();
                 }
             }
             toolStripLabel_save.Text = "50%";
         }         private void button_60_Click(object sender, EventArgs e)
         {
             if (toolStripProgressBar_save.Value < )
             {
                 for (int i = ; i < ; i++)
                 {
                     toolStripProgressBar_save.PerformStep();
                 }
             }
             toolStripLabel_save.Text = "60%";
         }         private void button_80_Click(object sender, EventArgs e)
         {
             if (toolStripProgressBar_save.Value < )
             {
                 for (int i = ; i < ; i++)
                 {
                     toolStripProgressBar_save.PerformStep();
                 }
             }
             toolStripLabel_save.Text = "80%";
         }         private void button_100_Click(object sender, EventArgs e)
         {
             if (toolStripProgressBar_save.Value < )
             {
                 for (int i = ; i < ; 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 = ;
             n.toolStripProgressBar_save.Maximum = ;
             //清空进度表
             n.toolStripProgressBar_save.Value = ;
             n.toolStripProgressBar_save.Step = ;             #region 保存过程-与单独按钮是一样的
             if (n.toolStripProgressBar_save.Value < )
             {                 for (int i = ; i < ; i++)
                 {
                     n.toolStripProgressBar_save.PerformStep();
                     n.toolStripLabel_save.Text = n.toolStripProgressBar_save.Value.ToString() + "%";
                 }
             }             Thread.Sleep();             if (n.toolStripProgressBar_save.Value < )
             {
                 for (int i = ; i < ; i++)
                 {
                     n.toolStripProgressBar_save.PerformStep();
                     n.toolStripLabel_save.Text = n.toolStripProgressBar_save.Value.ToString()+"%";
                 }
             }             Thread.Sleep();             if (n.toolStripProgressBar_save.Value < )
             {
                 for (int i = ; i < ; i++)
                 {
                     n.toolStripProgressBar_save.PerformStep();
                     n.toolStripLabel_save.Text = n.toolStripProgressBar_save.Value.ToString() + "%";
                 }
             }
             Thread.Sleep();             if (n.toolStripProgressBar_save.Value < )
             {
                 for (int i = ; i < ; i++)
                 {
                     n.toolStripProgressBar_save.PerformStep();
                     n.toolStripLabel_save.Text = n.toolStripProgressBar_save.Value.ToString() + "%";
                 }
             }
             Thread.Sleep();             if (n.toolStripProgressBar_save.Value < )
             {
                 for (int i = ; i < ; i++)
                 {
                     n.toolStripProgressBar_save.PerformStep();
                     n.toolStripLabel_save.Text = n.toolStripProgressBar_save.Value.ToString() + "%";
                 }
             }
             Thread.Sleep();             if (n.toolStripProgressBar_save.Value < )
             {
                 for (int i = ; i < ; i++)
                 {
                     n.toolStripProgressBar_save.PerformStep();
                     n.toolStripLabel_save.Text = n.toolStripProgressBar_save.Value.ToString() + "%";
                 }
             }
             n.toolStripLabel_save.Text = "Complete!";
             Thread.Sleep();
             #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;
         }
     }
