如何在Windows Form中实现URL Encoding/Decoding？

如果你想在Windows Forms中实现URL Encoding，HttpUtility类有一个shared (static)方法实现对字符串的URL 编码。下面就是一个例子：【注意要引用System.Web】

using System.Reflection.Metadata;
using System.Web;
using System.Windows.Controls;

Imports System
Imports System.Windows.Forms
Imports System.Drawing
Imports System.Web

Public Class Form1
Inherits System.Windows.Forms.Form

#Region " Windows 窗体设计器生成的代码 "
Public Sub New()
    MyBase.New()
    '该调用是 Windows 窗体设计器所必需的。
    InitializeComponent()
    '在 InitializeComponent() 调用之后添加任何初始化
End Sub

'窗体重写 dispose 以清理组件列表。
Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)
If disposing Then
    If Not (components Is Nothing) Then
        components.Dispose()
    End If
End If
MyBase.Dispose(disposing)
End Sub

'Windows 窗体设计器所必需的
Private components As System.ComponentModel.IContainer

'注意: 以下过程是 Windows 窗体设计器所必需的
'可以使用 Windows 窗体设计器修改此过程。
'不要使用代码编辑器修改它。
FriEnd WithEvents TextBox1 As System.Windows.Forms.TextBox
FriEnd WithEvents Button1 As System.Windows.Forms.Button
FriEnd WithEvents TextBox2 As System.Windows.Forms.TextBox
FriEnd WithEvents Label1 As System.Windows.Forms.Label
FriEnd WithEvents Button2 As System.Windows.Forms.Button
FriEnd WithEvents TextBox3 As System.Windows.Forms.TextBox
 < System.Diagnostics.DebuggerStepThrough() > Private Sub InitializeComponent()
