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 = 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;
        }
    }
