這篇文章主要介紹了C#實(shí)現(xiàn)winform用子窗體刷新父窗體及子窗體改變父窗體控件值的方法,涉及C#窗體交互的相關(guān)技巧,具有一定參考借鑒價(jià)值,需要的朋友可以參考下
本文實(shí)例講述了C#實(shí)現(xiàn)winform用子窗體刷新父窗體及子窗體改變父窗體控件值的方法。分享給大家供大家參考。具體如下:
第一種方法:
用委托,Form2和Form3是同一組
Form2
- using System;
- using System.Collections.Generic;
- using System.ComponentModel;
- 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
- using System;
- using System.Collections.Generic;
- using System.ComponentModel;
- using System.Data;
- using System.Drawing;
- using System.Text;
- using System.Windows.Forms;
- namespace TestMouseMove
- {
- public partial class Form3 : Form
- {
- private SetVisiableHandler m_setVisible;
- public Form3(SetVisiableHandler setvisible)
- {
- InitializeComponent();
- this.m_setVisible = setvisible;
- }
- private void btnVisible_Click(object sender, EventArgs e)
- {
- if (this.m_setVisible != null)
- {
- this.m_setVisible();
- }
- }
- }
- }
第二種方法:
用變量,Form4和Form5是同一組
Form4
- using System;
- using System.Collections.Generic;
- using System.ComponentModel;
- using System.Data;
- using System.Drawing;
- using System.Text;
- using System.Windows.Forms;
- namespace TestMouseMove
- {
- public partial class Form4 : Form
- {
- public Form4()
- {
- InitializeComponent();
- }
- #region 子窗口刷新父窗口的值
- private string strLabel1 = "";
- public string StrLabel1
- {
- get
- {
- return strLabel1;
- }
- set
- {
- strLabel1 = value;
- this.label1.Text = strLabel1;
- }
- }
- #endregion
- private void button1_Click(object sender, EventArgs e)
- {
- Form5 form5 = new Form5(this);//這里注意傳個(gè)this
- form5.Show();
- }
- }
- }
Form5
- using System;
- using System.Collections.Generic;
- using System.ComponentModel;
- using System.Data;
- using System.Drawing;
- using System.Text;
- using System.Windows.Forms;
- namespace TestMouseMove
- {
- public partial class Form5 : Form
- {
- Form4 form4 = new Form4();
- public Form5(Form4 formFrm)//這個(gè)構(gòu)造方法里有參數(shù)
- {
- form4 = formFrm; //這個(gè)必須要有
- InitializeComponent();
- }
- private void button1_Click(object sender, EventArgs e)
- {
- form4.StrLabel1 = this.textBox1.Text;
- }
- }
- }
希望本文所述對(duì)大家的C#程序設(shè)計(jì)有所幫助。
