Python甘泉GH 09-25 111

前言：

今天朋友们对“pythonautocad开发”可能比较珍视，各位老铁们都需要了解一些“pythonautocad开发”的相关内容。那么小编也在网摘上收集了一些对于“pythonautocad开发””的相关知识，希望咱们能喜欢，小伙伴们一起来学习一下吧！

现在学习VS2017 C# CAD2014，开始C# CAD二次开发第一步！！

1.exp1 => Class1.cs 代码如下：

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;using Autodesk.AutoCAD.ApplicationServices;using Autodesk.AutoCAD.DatabaseServices;using Autodesk.AutoCAD.EditorInput;using Autodesk.AutoCAD.Runtime;using Autodesk.AutoCAD.Colors;namespace exp1{    public class cSum    {        public void Sum()        {//System.Windows.Forms.messagebox.show("Hello World From VS C#(It's for Degbugging)","提示");            long s = 0;            for (int i = 1; i <= 101; i++)            {                s += i;            }            System.Windows.Forms.MessageBox.Show(s.ToString(), "提示");        }    }}

这个是使用cmd.json的文件的类，修改cmd.json文件的内容不必要重新编译类文件！

2.loadx => Class1.cs 代码如下：

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;using Autodesk.AutoCAD.ApplicationServices;using Autodesk.AutoCAD.DatabaseServices;using Autodesk.AutoCAD.EditorInput;using Autodesk.AutoCAD.Runtime;using Autodesk.AutoCAD.Colors;using System.Reflection;using System.IO;using Newtonsoft.Json;using Newtonsoft.Json.Linq;namespace Loadx{    public class loadx    {        private Action cmd;        [CommandMethod("DD")]        public void Reloadx()        {            #region CmdSum            CmdInfo cmdInfo = new CmdInfo();            string jsonFile = @"E:\VS\exp1\cmd.json";            using (System.IO.StreamReader file = System.IO.File.OpenText(jsonFile))            {                using (JsonTextReader reader = new JsonTextReader(file))                {                    JObject o = (JObject)JToken.ReadFrom(reader);                    cmdInfo.DllName = o["DllName"].ToString();                    cmdInfo.ClassName = o["ClassName"].ToString();                    cmdInfo.MethodName = o["MethodName"].ToString();                }            }            string DllName = cmdInfo.DllName;            string ClassName = cmdInfo.ClassName;            string MethodName = cmdInfo.MethodName;                //string DllName = "exp1.dll";                //string ClassName = "exp1.cSum";                //string MethodName = "Sum";            #endregion            #region Don't                var adapterfileInfo = new FileInfo(Assembly.GetExecutingAssembly().Location);            var targetFilePath = Path.Combine(adapterfileInfo.DirectoryName, DllName);            var targetAssembly = Assembly.Load(File.ReadAllBytes(targetFilePath));            var targetType = targetAssembly.GetType(ClassName);            var targetMethod = targetType.GetMethod(MethodName);            var targetObject = Activator.CreateInstance(targetType);            cmd = () => targetMethod.Invoke(targetObject, null);            try            {                cmd?.Invoke();            }            catch (System.Exception ex)            {            System.Windows.Forms.MessageBox.Show(ex.Message, "Tips1");            };            #endregion        }    }    public class CmdInfo    {        public string DllName { get; set; }        public string ClassName { get; set; }        public string MethodName { get; set; }    }}

3.cmd.json 代码如下：

添加图片注释，不超过 140 字（可选）

{"DllName":"exp1.dll","ClassName":"exp1.cSum","MethodName":"Sum"}

这个类是不用cmd.json文件的类！

4.loadx => Class2.cs 代码如下：

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;using Autodesk.AutoCAD.ApplicationServices;using Autodesk.AutoCAD.DatabaseServices;using Autodesk.AutoCAD.EditorInput;using Autodesk.AutoCAD.Runtime;using Autodesk.AutoCAD.Colors;using System.Reflection;using System.IO;using Newtonsoft.Json;using Newtonsoft.Json.Linq;namespace Loadx{    public class loadx1    {        private Action cmd1;        [CommandMethod("DD1")]        public void Reloadx()        {            #region CmdSum            string DllName = "exp1.dll";            string ClassName = "exp1.cSum";            string MethodName = "Sum";            #endregion            #region Don't            var adapterfileInfo = new FileInfo(Assembly.GetExecutingAssembly().Location);            var targetFilePath = Path.Combine(adapterfileInfo.DirectoryName, DllName);            var targetAssembly = Assembly.Load(File.ReadAllBytes(targetFilePath));            var targetType = targetAssembly.GetType(ClassName);            var targetMethod = targetType.GetMethod(MethodName);            var targetObject = Activator.CreateInstance(targetType);            cmd1 = () => targetMethod.Invoke(targetObject, null);            try            {                cmd1?.Invoke();            }            catch (System.Exception ex)            {            System.Windows.Forms.MessageBox.Show(ex.Message, "Tips1");            };            #endregion        }  }    public class CmdInfo1    {        public string DllName { get; set; }        public string ClassName { get; set; }        public string MethodName { get; set; }    }}

效果：

打开CAD2014，在命令行输入：netload命令回车！选择如图中的动态链接库文件！

输入命令：DD命令回车！

添加图片注释，不超过 140 字（可选）

提示：.exp1 => Class1.cs

修改后只要重新编译exp1即可，不用重新关闭重启CAD。

如果要修改启动的类，可以直接修改cmd.json文件对应的项即可。

这里再做一点补充！每次都要使用netload加载动态链接库文件也挺烦的。
