如何实现FORM的值返回到调用页
比如我在把form2的值传给Form1点击button以后会显示好几个FORM页
------解决方案--------------------在窗体1里面有一个一个Button 
 private void button1_Click(object sender, System.EventArgs e) 
 { 
   Class1.s =  "我是谁? "; 
   Form2 obj = new Form2(); 
   obj.ShowDialog(); 
 }   
 在窗体2里面有一个TextBox和一个Button 
 private void button1_Click(object sender, System.EventArgs e) 
 		{ 
 			this.textBox1.Text = Class1.s; 
 		}   
 还有一个类 
 using System;   
 namespace WindowsApplication1 
 { 
 	///  <summary>  
 	/// Class1 的摘要说明。 
 	///  </summary>  
 	public class Class1 
 	{ 
 		public Class1() 
 		{  			 
 		} 
 		public static string s = null; 
 	} 
 }   
 我运行的是可以的....
------解决方案--------------------用委托的方式传递   
 FROM2中   
   public delegate void changelabel(string s); 
   public event changelabel change;   
   private void button1_Click(object sender, System.EventArgs e) 
   { 
    if(change != null) 
    { 
     change(this.textBox1.Text); 
    }     
   }   
 FROM 1中   
   private void button2_Click(object sender, System.EventArgs e) 
   { 
    frmlabel frm = new frmlabel(); 
    frm.change += new frmlabel.changelabel(myevent); 
    frm.Show();   
   } 
   private void myevent(string s) 
   { 
    this.label2.Text = s; 
   } 
------解决方案--------------------估计楼主需要这样的代码才能满足要求,借用songcan(当爱已成往事) ( ) 信誉:100 的代码。   
 用委托的方式传递   
 Form2   
   public delegate void changelabel(double s); 
   public event changelabel change;   
   private void button1_Click(object sender, System.EventArgs e) 
   { 
           double R; 
 	 double a= Convert.ToDouble(this.textBox1.Text); 
 	 double b=Convert.ToDouble(this.textBox2.Text); 
 	 R=a+b; 
           if(change != null) 
           { 
             change(R); 
           }   
   }   
 Form1   
 public Form1() 
 { 
      InitializeComponent(); 
 } 
 private void button2_Click(object sender, System.EventArgs e) 
 { 
    Form2 ff = new Form2(); 
    ff.change += new Form2.changelabel(myevent); 
    ff.Show(); 
 } 
 private void myevent(double s) 
 { 
      this.textBox1.Text=Convert.ToString(s); 
 }
