在使用Advanced Installers制作安裝包時，發現卸載功能只會卸載之前打包的文件，程序生成的文件（例如日志文件、緩存信息文件等）不會被刪除，可能導致卸載后再安裝出現問題（ORZ！！好吧，主要是測試和產品要求卸載全部刪除）。

在查資料是發現可以使用Custom Action來實現，例如：https://blog.csdn.net/qq_20849387/article/details/78422081，https://blog.csdn.net/qq_20849387/article/details/78422432

不過網上資料不全，這里做下記錄：

1. 安裝WIX TOOLSET，最新版本WiX Toolset v3.11.2，這能保證能夠編譯生成Custom Action。
2. 安裝Visual Studio，以2019為例，在拓展里面搜索WIX TOOLSET，安裝WiX Toolset Visual Studio 2019 Extension，這可以讓你在vs添加Custon Action項目
3. 以上完成后新建“C# Custom Action Project for WiX v3”項目，然后安裝https://blog.csdn.net/qq_20849387/article/details/78422432的步驟操作即可。

補一段刪除全部文件的代碼

public class CustomActions
    {
        [CustomAction]
        public static ActionResult CustomAction1(Session session)
        {
            session.Log("Begin CustomAction1");

            string manufacturer = session["Manufacturer"];
            string productName = session["ProductName"];

            string systembit = Distinguish64or32System();


            //通過注冊表的值，獲取軟件安裝路勁
            RegistryKey key = Registry.LocalMachine;
            RegistryKey software;

            if(systembit == "64")
            {
                software = key.OpenSubKey("SOFTWARE\\Wow6432Node\\" + manufacturer + "\\" + productName);
            }
            else
            {
                software = key.OpenSubKey("SOFTWARE\\" + manufacturer + "\\" + productName);
            }
            string installpath = software.GetValue("Path").ToString() + productName;

            //MessageBox.Show(installpath);

            DirectoryInfo ip = new DirectoryInfo(installpath);

            if(ip.Exists)
            {
                try
                {
                    RemoveSubDirectory(ip);
                    ip.Delete();
                }
                catch
                {
                    return ActionResult.Failure;
                }
            }

            //MessageBox.Show(systembit);

            return ActionResult.Success;
        }


        private static void RemoveSubDirectory(DirectoryInfo uper)
        {
            foreach (FileInfo subFile in uper.GetFiles())
            {
                subFile.Delete();
            }
            foreach (DirectoryInfo sub in uper.GetDirectories())
            {
                if (sub.GetFiles().Length > 0 || sub.GetDirectories().Length > 0)
                    RemoveSubDirectory(sub);
                sub.Delete();
            }
        }

        private static string Distinguish64or32System()
        {
            try
            {
                string addressWidth = String.Empty;
                ConnectionOptions mConnOption = new ConnectionOptions();
                ManagementScope mMs = new ManagementScope("//localhost", mConnOption);
                ObjectQuery mQuery = new ObjectQuery("select AddressWidth from Win32_Processor");
                ManagementObjectSearcher mSearcher = new ManagementObjectSearcher(mMs, mQuery);
                ManagementObjectCollection mObjectCollection = mSearcher.Get();
                foreach (ManagementObject mObject in mObjectCollection)
                {
                    addressWidth = mObject["AddressWidth"].ToString();
                }
                return addressWidth;
            }
            catch (Exception ex)
            {
                return String.Empty;
            }
        }
    }

 

在網上查資料時發現以下方案，但是未驗證，后面有時間再填坑。
