一般做网站都在什么网做搜索网

一、创建WPF项目及文件

1、创建项目

打开VS2022,创建一个WPF项目，如下所示

2、创建文件夹及文件

创建资源文件夹，添加字体图标文件，添加 Menu样式文件，如下所示

创建公共附加属性用控件类库,并创建对应的 ControlAttachProperty 类文件如下：

3、添加引用

右键 Menu_WPF 添加引用，将类库引用到当前项目

二、代码实现

2.ControlAttachProperty类

代码如下（示例）：

using System;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;

using ComboBox = System.Windows.Controls.ComboBox;
using OpenFileDialog = Microsoft.Win32.OpenFileDialog;
using RadioButton = System.Windows.Controls.RadioButton;
using RichTextBox = System.Windows.Controls.RichTextBox;
using TextBox = System.Windows.Controls.TextBox;namespace Common.UserControl.Extession
