 第一步：创建WPF类库，并写CAD调用方法

 

 

 

 

main页面添加以下内容：

    <Grid><Button Height="50" Click="Button_Click" Margin="285,184,157,185" Content="打开程序" Tag=""/><TextBox x:Name="txtPath" HorizontalAlignment="Left" Height="23" Margin="245,110,0,0" TextWrapping="Wrap" Text="D:\Program Files (x86)\Tencent\WeChat\WeChat.exe" VerticalAlignment="Top" Width="450"/></Grid>

main后台添加以下内容：

        private void Button_Click(object sender, RoutedEventArgs e){string Path = "";try{Path = @"D:\Program Files (x86)\Tencent\WeChat\WeChat.exe";if (!string.IsNullOrEmpty(txtPath.Text)){Path = txtPath.Text;}System.Diagnostics.Process.Start(Path);Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.CurrentDocument.Editor.WriteMessage("启动成功:" + Path);}catch (Exception ex){Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.CurrentDocument.Editor.WriteMessage("路径：" + Path + ",启动异常," + ex.Message);}}

新增一个类，写CAD执行方法：

using Autodesk.AutoCAD.Runtime;
using Autodesk.AutoCAD.ApplicationServices;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;namespace wpfdemo
{public class Class1{[CommandMethod("OpenExe")] public void OpenExe(){MainWindow main = new MainWindow();Application.ShowModelessWindow(main);}}
}

 

程序开发完成，生成动态库 dll：

  第二步：打开CAD，引用生成的动态库，并调用方法打开画面

CAD引用dll： 

 

 CAD调用wpf动态库的方法： 

命令输入方法名：openexe

 执行命令后，CAD自动打开WPF的画面
