Wix自定義操作屬性 - 爲什麼這不起作用？

Question

我有以下維克斯片段，調用取決於它是否安裝或卸載兩個自定義操作之一：

<?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> 

安裝CA按預期工作。我在action中設置了一些屬性Id = caSetpropertyForInstall，然後操作caRegisterDriver調用我的C＃託管自定義操作。 C＃代碼查詢的自定義動作的屬性，像這樣：使用

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

相同的C＃方法是否安裝或卸載，而且前面已經指出，這在安裝階段工作。

我的問題是，在卸載階段，我收到一個異常：

我看不到我如何處理安裝和卸載任何區別，所以我很困惑，爲什麼這是。我錯過了明顯的東西嗎？

Answer 1

您將自定義操作「caUnregisterDriver」安排爲立即執行，而不是延期執行。它不會有一個CustomActionData屬性來反序列化到集合中。

順便說一句我也沒有看到回滾和提交自定義操作，所以我也會關注。
