百分比读数的ProgressBar

Question

我试图把一个label1.text = progressbar1.value.ToString();，它不会读出它有多少进展。这是我迄今为止的一些帮助。

namespace WindowsFormsApplication1 
{ 
    public partial class Form1 : Form 
    { 
     public Form1() 
     { 
      InitializeComponent(); 

      progressBar1.Value = s_Checks * (progressBar1.Maximum/TOTAL_CHECKBOXES); 

      label1.Text = progressBar1.Value.ToString(); 
     } 

     private void Form1_Load(object sender, EventArgs e) 
     { 
     } 

     private const Int32 TOTAL_CHECKBOXES = 4; 

     private static Int32 s_Checks = 0; 

     private void OnCheckedChanged(object sender, EventArgs e) 
     { 
      if (((CheckBox)sender).Checked) 
       ++s_Checks; 
      else 
       --s_Checks; 

      progressBar1.Value = s_Checks * (progressBar1.Maximum/TOTAL_CHECKBOXES); 
     } 

     private void progressBar1_Click(object sender, EventArgs e) 
     { 
     } 

     private void checkBox1_CheckedChanged(object sender, EventArgs e) 
     { 
      if (((CheckBox)sender).Checked) 
       ++s_Checks; 
      else 
       --s_Checks; 

      progressBar1.Value = s_Checks * (progressBar1.Maximum/TOTAL_CHECKBOXES); 
     } 

     private void checkBox2_CheckedChanged(object sender, EventArgs e) 
     { 
      if (((CheckBox)sender).Checked) 
       ++s_Checks; 
      else 
       --s_Checks; 

      progressBar1.Value = s_Checks * (progressBar1.Maximum/TOTAL_CHECKBOXES); 
     } 

     private void checkBox3_CheckedChanged(object sender, EventArgs e) 
     { 
      if (((CheckBox)sender).Checked) 
       ++s_Checks; 
      else 
       --s_Checks; 

      progressBar1.Value = s_Checks * (progressBar1.Maximum/TOTAL_CHECKBOXES); 
     } 

     private void checkBox4_CheckedChanged(object sender, EventArgs e) 
     { 
      if (((CheckBox)sender).Checked) 
       ++s_Checks; 
      else 
       --s_Checks; 

      progressBar1.Value = s_Checks * (progressBar1.Maximum/TOTAL_CHECKBOXES); 
     } 

     private void button1_Click(object sender, EventArgs e) 
     { 
      if (checkBox1.Checked || checkBox2.Checked || checkBox3.Checked || checkBox4.Checked == true) 
      { 
       checkBox1.Checked = false; 
       checkBox2.Checked = false; 
       checkBox3.Checked = false; 
       checkBox4.Checked = false; 
      } 
     } 

     private void clearCheckBoxToolStripMenuItem_Click(object sender, EventArgs e) 
     { 
      if (checkBox1.Checked || checkBox2.Checked || checkBox3.Checked || checkBox4.Checked == true) 
      { 
       checkBox1.Checked = false; 
       checkBox2.Checked = false; 
       checkBox3.Checked = false; 
       checkBox4.Checked = false; 
      } 
     } 

     private void exitToolStripMenuItem_Click(object sender, EventArgs e) 
     { 
      this.Close(); 
     } 

     private void label1_Click(object sender, EventArgs e) 
     { 
     } 

     private void timer1_Tick(object sender, EventArgs e) 
     { 
      label1.Text = progressBar1.Value.ToString(); 
     } 
    } 
}

public Form1() 
{ 
    InitializeComponent(); 

    progressBar1.Value = s_Checks * (progressBar1.Maximum/TOTAL_CHECKBOXES); 
    label1.Text = progressBar1.Value.ToString(); 

    timer1.Tick += new EventHandler(timer1_Tick); 
    timer1.Interval = 1000; 
    timer1.Enabled = true; 
    timer1.Start(); 
}
