Question

我有以下Wix片段，根据是安装还是卸载调用两个自定义操作之一：

<?xml version="1.0" encoding="UTF-8" ?>
<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi">
  <?include $(sys.CURRENTDIR)\Config.wxi?>
  <Fragment>
    <CustomAction Id="caSetPropertyForInstall" Property="caRegisterDriver" Value="DeviceId=$(var.DriverId);DeviceName=$(var.ChooserName)" />
    <CustomAction Id="caSetPropertyForUninstall" Property="caUnregisterDriver" Value="DeviceId=$(var.DriverId);DeviceName=$(var.ChooserName)" />
    <Binary Id="DriverRegCA" SourceFile="$(var.ASCOM.Wix.CustomActions.TargetDir)\$(var.ASCOM.Wix.CustomActions.TargetName).CA.dll" />
    <CustomAction Id="caRegisterDriver" BinaryKey="DriverRegCA" DllEntry="RegisterAscomDriver" Execute="deferred" Return="check" />
    <CustomAction Id="caUnregisterDriver" BinaryKey="DriverRegCA" DllEntry="UnregisterAscomDriver" Execute="immediate" Return="ignore" />
    <InstallExecuteSequence>
      <Custom Action="caSetPropertyForInstall" Before="caRegisterDriver" />
      <Custom Action="caSetPropertyForUninstall" Before="caUnregisterDriver" />

      <!-- Execute during install -->
      <Custom Action="caRegisterDriver" Before="InstallFinalize">NOT Installed</Custom>

      <!-- Execute during uninstall -->
      <Custom Action="caUnregisterDriver" Before="RemoveFiles">REMOVE ~= "ALL"</Custom>
    </InstallExecuteSequence>
  </Fragment>
</Wix>

安装CA按预期工作。我在操作Id = caSetpropertyForInstall中设置了一些属性，然后动作caRegisterDriver调用我的C＃托管自定义操作。 C＃代码查询自定义操作属性，如下所示：

var deviceId = session.CustomActionData["DeviceId"];
var deviceName = session.CustomActionData["DeviceName"];
Diagnostics.TraceInfo("Property DeviceId = [{0}]", deviceId);
Diagnostics.TraceInfo("Property DeviceName = [{0}]", deviceName);

使用相同的C＃方法，无论是安装还是卸载，如上所述，这在安装阶段都有效。

我的问题是在卸载阶段，我收到一个例外：

我看不出我处理安装和卸载的方式有什么不同，所以我很困惑为什么会这样。我错过了一些明显的东西吗？

Answer 1

您将自定义操作“caUnregisterDriver”安排为立即执行，而不是延迟执行。它没有CustomActionData属性来反序列化到集合中。

BTW我也看不到回滚和提交自定义操作，所以我也会关注它。

Wix自定义操作属性 - 为什么这不起作用？
