以編程方式添加菜單

Question

我一直在用Java編寫大量代碼，發現創建控制檯或表單應用程序非常簡單。事實上，所有人都需要添加一個表單並顯示該表單。可以這麼說，就像一個餅乾一樣簡單。但是現在我有了一個用Visual C＃編寫的大項目，我沒有用過這麼多。我想，我不確定自己是否正確，但控制檯應用程序是C＃就是這樣一個控制檯應用程序，它不能接受任何鼠標動作事件。我希望能夠從窗體內部向C＃添加控件，就像在Java中一樣。添加一個按鈕，或添加一個菜單。但在C＃中，有幾個文件可以打開，屬性，assemblyinfo.cs，form1.cs等等。下面的代碼在form designer.cs中。

那麼從編程的角度而不是設計視覺立場的角度來看添加組件的最佳方式在哪裏？

namespace WindowsFormsTestMenuApplication 
{ 
    partial class Form1 
    { 
     /// <summary> 
     /// Required designer variable. 
     /// </summary> 
     private System.ComponentModel.IContainer components = null; 

     /// <summary> 
     /// Clean up any resources being used. 
     /// </summary> 
     /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param> 
     protected override void Dispose(bool disposing) 
     { 
      if (disposing && (components != null)) 
      { 
       components.Dispose(); 
      } 
      base.Dispose(disposing); 
     } 

     #region Windows Form Designer generated code 

     /// <summary> 
     /// Required method for Designer support - do not modify 
     /// the contents of this method with the code editor. 
     /// </summary>

Answer 1

您是否試圖在運行時添加控件？如果是這樣，正如SLaks所述，您只需創建一個新的控件實例並將其添加到您的表單中即可。

// Add a menustrip to the form. 
MenuStrip menuStrip = new MenuStrip(); 
menuStrip.Dock = DockStyle.Top; 
this.Controls.Add(menuStrip); 

否則，爲什麼不利用可視化設計器將控件添加到表單中？

Answer 2

WinForms控件是常規對象，就像AWT或Swing一樣。

您可以創建一個new ToolStripItem()，設置其屬性，然後將其添加到DropDownItems集合。

Answer 3

聽起來有點像我一般的設計/方法問題。 爲什麼不使用WinForm的WPF？在Visual Studio中給你一個非常方便的設計器。您可以以所見即所得風格輕鬆構建您的GUI。支持數據綁定 - 一旦熟悉 - 非常方便。 但是，稍後您仍然可以在運行時添加控件等，請參閱Breems答案。 注意：如果您使用WPF，則需要使用Windows的調度程序，如果要從Windows之外的其他線程添加控件。
