Transfer values between different forms

One: Before and after running, the implementation function takes the text value of the lable of the subform out to the lable text of the parent form

Two: All code

A, parent form

 using system;using system.collections.generic;using system.componentmodel;using system.data;using System.drawing;using system.linq;using system.text;using system.windows.forms;namespace passV{public partial class Fo        Rm1:form {public Form1 () {InitializeComponent (); }///<summary>//lable The text value of the subform to the text of the parent form's lable///</summary>//<para        M name= "txt" ></param> private void Getlabletxt (string text) {this.label1.Text = text; }///<summary>///Open Subform///</summary>//<param name= "Sender" ><        /param>//<param name= "E" ></param> private void button2_click (object sender, EventArgs e)            {Son son = new son (); if (DialogResult.OK = = son. ShowDialog ()) {Getlabletxt (son.            Text); }}}} 
 
 B, Subform 

Using system;using system.collections.generic;using system.componentmodel;using system.data;using System.Drawing; Using system.linq;using system.text;using system.windows.forms;namespace passv{public    partial class Son:form    {        private string text;        public string Text        {            get {return Text;}            set {text = value;}        }                Public Son ()        {            InitializeComponent ();        }        <summary>        //Confirm///</summary>//<param name= "sender" ></param>/ <param name= "E" ></param>        private void Button1_Click (object sender, EventArgs e)        {            Text = Label1. Text;            This. DialogResult = DialogResult.OK;            This. Close ();}}    }
