C#实现窗体间传递数据实例

本文以实例详述了c#两个窗体之间传递数据的实现方法，具体的操作步骤如下：

1.建立两个窗体，并采用公用变量值传递：

public partial class form1 : form //父窗体
 {
   public string name="";
   public form1()
   {
     initializecomponent();
   }
   private void newbtn_click(object sender, eventargs e)
   {
     form2 form2 =new form2();
     form2.showdialog();
     if (form2.dialogresult == dialogresult.ok)
     {
       textbox1.text = form2.name;
       form2.close();
     }
   }
 }

public partial class form2 : form // 子窗体
  {
    public string name
   {
      set { textbox1.text = value; }
      get { return textbox1.text; }
    }
    public form2()
    {
      initializecomponent();
    }
    private void ok_click(object sender, eventargs e)
    {
      if (textbox1.text == "")
      {
        messagebox.show("input!");
        return;
      }
      dialogresult = dialogresult.ok;
      close();
    }
  }

2.使用地址方式传递

public partial class form1 : form //parent form
 
  {
    public string name="";
    public form1()
    {
      initializecomponent();
    }
    private void newbtn_click(object sender, eventargs e)
    {
      form2 form2 =new form2();
      form2.owner = this;//form2的指针指向form1
      form2.showdialog();
      textbox1.text = form2.name;
      form2.close(); 
    }
  }

public partial class form2 : form //son form
  {
    public string name
   {
      set { textbox1.text = value; }
      get { return textbox1.text; }
    }
    public form2()
    {
      initializecomponent();
    }
    private void ok_click(object sender, eventargs e)
    {
      if (textbox1.text == "")
      {
        messagebox.show("input!");
        return;
      }
      form1 form1 = (form1)this.owner;//form2的父窗体指针赋给form1
      close();
    }
  }
