C#中数据的传递以及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 = 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;
}
}
