利用窗體的自定義屬性實現窗體傳值

　　第步在解決方案上添加一個窗體Form;並添加textBoxtextBoxButton將Button的標題設為確定DialogResult屬性設為OK
   第步在窗體Form的類代碼中添加兩個私有字段: _username_password並添加兩個public屬性UserNamePassword代碼如下
public partial class Form: Form
{
       private string _username;
       private string _password;
       public string UserName
       {
           get
           {
               return _username;
           }
           set
           {
               _username=value;
           }
       }
       public string Password
       {
           get
           {
               return _password;
           }
           set
           {
               _password=value;
           }
       }
      
}

　　第步窗體間相互傳值演示
在Form添加一個的Botton一個comboBox在Botton_Click函數中如下代碼
private void button_Click(object senderEventArgs e)
{
      Form myForm = new Form();
      myFormUserName=Richard;//Form向Form傳值！！！
      myFormPassword=pwd;
      DialogResult result= myFormShowDialog();
      if(result==DialogResultOK)
      {
           comboBoxItemsAdd(myFormUserName);////Form向Form傳值！！！
           comboBoxItemsAdd(myFormPassword);
       }
}
  要充分演示上述功能還需要對Form的代碼作如下完善
第在Form_Load中添加如下代碼:
private Form_Load(object senderEventArgs e)
{
    textBoxText=_username;
    textBoxText=_password;
}
第在textBoxtextBox的textChanged事件中添加如下代碼:
private void textBox_TextChanged(object senderEventArgs e)
{
    thisUserName=textBoxText;
}
private void textBox_TextChanged(object senderEventArgs e)
{
    thisPassword=textBoxText;
}
