Winform数据即时更新 父窗体子窗体即时更新

第一种方法:
用委托,Form2和Form3是同一组
Form2

C#代码 
  1. using System; 
  2. using System.Collections.Generic; 
  3. using System.ComponentModel; 
  4. using System.Data; 
  5. using System.Drawing; 
  6. using System.Text; 
  7. using System.Windows.Forms;

  9. namespace TestMouseMove 
  10. { 
  11.     publicdelegatevoid SetVisiableHandler(); 
  12.  
  13.     public partial class Form2 : Form 
  14.     { 
  15.         public Form2() 
  16.         { 
  17.             InitializeComponent(); 
  18.         } 
  19.         privatevoid button1_Click(object sender, EventArgs e) 
  20.         { 
  21.             Form3 frm = new Form3(new SetVisiableHandler(SetVisiable)); 
  22.             frm.Show(); 
  23.         } 
  24.  
  25.         privatevoid SetVisiable() 
  26.         { 
  27.             SetVisiable(this.label1, !this.label1.Visible); 
  28.         } 
  29.  
  30.         privatevoid SetVisiable(Control control, bool visiable) 
  31.         { 
  32.             if (this.Controls.Contains(control)) 
  33.             { 
  34.                 control.Visible = visiable; 
  35.             } 
  36.         } 
  37.  
  38.     } 
  39. }  
using System;
using System.Collections.Generic;

using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

namespace TestMouseMove
{
    public delegate void SetVisiableHandler();

    public partial class Form2 : Form
    {
        public Form2()
        {
            InitializeComponent();
        }
        private void button1_Click(object sender, EventArgs e)
        {
            Form3 frm = new Form3(new SetVisiableHandler(SetVisiable));
            frm.Show();
        }

        private void SetVisiable()
        {
            SetVisiable(this.label1, !this.label1.Visible);
        }

        private void SetVisiable(Control control, bool visiable)
        {
            if (this.Controls.Contains(control))
            {
                control.Visible = visiable;
            }
        }

    }
}

Form3

  7. using System.Windows.Forms; 
  8.  
  9. namespace TestMouseMove 
  10. { 
  11.     public partial class Form3 : Form 
  12.     { 
  13.         private SetVisiableHandler m_setVisible; 
  14.  
  15.         public Form3(SetVisiableHandler setvisible) 
  16.         { 
  17.             InitializeComponent(); 
  18.             this.m_setVisible = setvisible; 
  19.         } 
  20.         privatevoid btnVisible_Click(object sender, EventArgs e) 
  21.         { 
  22.             if (this.m_setVisible != null) 
  23.             { 
  24.                 this.m_setVisible(); 
  25.             } 
  26.         }

                this.m_setVisible();
            }
        }

    }
}

第二种方法:
用变量,Form4和Form5是同一组
Form4

C#代码

  12.     { 
  13.         public Form4() 
  14.         { 
  15.             InitializeComponent(); 
  16.         } 
  18.         #region 子窗口刷新父窗口的值 
  19.  
  20.         privatestring strLabel1 = "";

  33.         } 
  34.         #endregion 
  35.  
  36.         privatevoid button1_Click(object sender, EventArgs e) 
  37.         { 
  38.             Form5 form5 = new Form5(this);//这里注意传个this 
  39.             form5.Show(); 
  40.         }

            {
                strLabel1 = value;
                this.label1.Text = strLabel1;
            }
        }
        #endregion

        private void button1_Click(object sender, EventArgs e)
        {
            Form5 form5 = new Form5(this);//这里注意传个this
            form5.Show();

Form5

  7. using System.Windows.Forms; 
  8.  
  9. namespace TestMouseMove 
  10. { 
  11.     public partial class Form5 : Form 
  12.     { 
  13.         Form4 form4 = new Form4(); 
  14.  
  15.         public Form5(Form4 formFrm)//这个构造方法里有参数 
  16.         { 
  17.             form4 = formFrm; //这个必须要有 
  18.             InitializeComponent(); 
  19.         } 
  20.  
  21.         
  22.         privatevoid button1_Click(object sender, EventArgs e) 
  23.         { 
  24.             form4.StrLabel1 = this.textBox1.Text; 
  25.         } 
  26.     } 
  27. }  
using System;
using System.Collections.Generic;

        {
            form4 = formFrm; //这个必须要有
            InitializeComponent();
        }

       
        private void button1_Click(object sender, EventArgs e)
        {
