一、以下是網路上可搜尋到的次序

   當 Windows Form 應用程式啟動時，會以下列順序引發主要表單的啟動事件：
        System.Windows.Forms.Control.HandleCreated
        System.Windows.Forms.Control.BindingContextChanged
        System.Windows.Forms.Form.Load
        System.Windows.Forms.Control.VisibleChanged
        System.Windows.Forms.Form.Activated
        System.Windows.Forms.Form.Shown

    當應用程式關閉時，會以下列順序引發主要表單的關閉事件：         
        System.Windows.Forms.Form.Closing
        System.Windows.Forms.Form.FormClosing
        System.Windows.Forms.Form.Closed
        System.Windows.Forms.Form.FormClosed
        System.Windows.Forms.Form.Deactivate

二、以下是我測試的次序，全部protected override 這些事件，並且在其base.的前後分別處理一次，如下

  protected override void OnLoad(EventArgs e) { textBox1.Text += "OnLoad1" + "/r/n"; base.OnLoad(e); textBox1.Text += "OnLoad2" + "/r/n"; }

OnClientSizeChanged1
OnClientSizeChanged2
OnClientSizeChanged1
OnClientSizeChanged2

// Loyout要多次執行
OnLayout1 
OnLayout2
OnHanleCreated1
OnHanleCreated2
OnInvalidated1
OnInvalidated2

// 注意這裡的一點點變化
OnCreateControl1
OnLoad1
OnLoad2
OnCreateControl2

//
OnLayout1
OnLayout2
OnActivated1
OnActivated2
OnShown1
OnShown2
OnPain1
OnPain2

希望這個次序能給大家帶來用處。。可以在不同事件中去處理所需要的程式碼

三、以下是程式碼源。C# 2008 Express

using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; // using System.Linq; using System.Text; using System.Windows.Forms; namespace WindowsFormsApplication1 { public partial class Form1 : Form { public Form1() { InitializeComponent(); } // 輸出窗體事件的執行次序 protected override void OnActivated(EventArgs e) { textBox1.Text += "OnActivated1" + "/r/n"; base.OnActivated(e); textBox1.Text += "OnActivated2" + "/r/n"; } protected override void OnClientSizeChanged(EventArgs e) { textBox1.Text += "OnClientSizeChanged1" + "/r/n"; base.OnClientSizeChanged(e); textBox1.Text += "OnClientSizeChanged2" + "/r/n"; } protected override void OnCreateControl() { textBox1.Text += "OnCreateControl1" + "/r/n"; base.OnCreateControl(); textBox1.Text += "OnCreateControl2" + "/r/n"; } protected override void OnDeactivate(EventArgs e) { textBox1.Text += "OnDeactivate1" + "/r/n"; base.OnDeactivate(e); textBox1.Text += "OnDeactivate2" + "/r/n"; } protected override void OnHandleCreated(EventArgs e) { textBox1.Text += "OnHanleCreated1" + "/r/n"; base.OnHandleCreated(e); textBox1.Text += "OnHanleCreated2" + "/r/n"; } protected override void OnHandleDestroyed(EventArgs e) { textBox1.Text += "OnHanleDestoryed1" + "/r/n"; base.OnHandleDestroyed(e); textBox1.Text += "OnHanleDestoryed2" + "/r/n"; } protected override void OnInvalidated(InvalidateEventArgs e) { textBox1.Text += "OnInvalidated1" + "/r/n"; base.OnInvalidated(e); textBox1.Text += "OnInvalidated2" + "/r/n"; } protected override void OnLayout(LayoutEventArgs levent) { textBox1.Text += "OnLayout1" + "/r/n"; base.OnLayout(levent); textBox1.Text += "OnLayout2" + "/r/n"; } protected override void OnLoad(EventArgs e) { textBox1.Text += "OnLoad1" + "/r/n"; base.OnLoad(e); textBox1.Text += "OnLoad2" + "/r/n"; } protected override void OnPaint(PaintEventArgs e) { textBox1.Text += "OnPain1" + "/r/n"; base.OnPaint(e); textBox1.Text += "OnPain2" + "/r/n"; } protected override void OnShown(EventArgs e) { textBox1.Text += "OnShown1" + "/r/n"; base.OnShown(e); textBox1.Text += "OnShown2" + "/r/n"; } } }
