運行時隱藏/顯示按鈕

Question

我需要您對c＃和一些圖形問題的幫助：我正在開發一個非常簡單的應用程序。有一種獨特的形式叫DeltaPregView，名爲DeltaPregController形式的控制器和一個類，它包含該項目的主要：

主類：

using System; 
using System.Linq; 
using System.Collections.Generic; 
using System.Windows.Forms; 

namespace deltaPreg 
{ 
    static class Program 
    { 
     [MTAThread] 
     static void Main() 
     { 
      //create the view 
      DeltaPregView view = new DeltaPregView(); 
      //link the view to the APP 
      Application.Run(view); 
      //initialize the controller of the APP 
      DeltaPregController controller = new DeltaPregController(view); 
     } 
    } 
} 

查看該類：

using System; 
using System.Linq; 
using System.Collections.Generic; 
using System.ComponentModel; 
using System.Data; 
using System.Drawing; 
using System.Text; 
using System.Windows.Forms; 

namespace deltaPreg 
{ 
    public partial class DeltaPregView : Form 
    { 
     public DeltaPregView() 
     { 
      InitializeComponent(); 

     } 

     public void init() 
     { 
      prova.Visible = false; 
     } 

    } 
} 

和控制器的視圖：

using System; 
using System.Linq; 
using System.Collections.Generic; 
using System.Text; 

namespace deltaPreg 
{ 
    class DeltaPregController 
    { 
     #region variables 
     private DeltaPregView view; 
     #endregion 

     public DeltaPregController(DeltaPregView view) 
     { 
      this.view = view; 
      //start the reading process 
      start(); 
     } 
     private void start() 
     { 
      view.init(); 
     } 
    } 
} 

我想到h找到叫做「prova」的按鈕，但是我的程序沒有任何變化。我是winforms管理的新手，提前感謝你。

問題是，在打電話init功能之前打印表格DeltaPregView。要解決這個

一種方式是通過更換這些線路：

//link the view to the APP 
    Application.Run(view); 
    //initialize the controller of the APP 
    DeltaPregController controller = new DeltaPregController(view); 

要：

//initialize the controller of the APP 
    DeltaPregController controller = new DeltaPregController(view); 
    //link the view to the APP 
    Application.Run(view);
