我们有一个自定义操作,必须在删除文件前的回滚期间执行。我们如何添加特定的自定义操作作为回滚期间的第一步执行?Wix-在回滚期间调用自定义操作

我们有下面的代码,但它不工作。

<CustomAction Id="Delete_Directory_Rollback" BinaryKey="UnifiedAgentCustomActions.dll" DllEntry="DeleteDirectory" Execute="rollback" /> 
    <Custom Action="Delete_Directory_Rollback" Before="RemoveFiles" >NOT (REMOVE="ALL")</Custom> 

自定义操作

string InstallPath = session["INSTALLDIR"]; 
    DeleteDir(InstallPath, session); 

错误消息:

Exception thrown by custom action: 
    System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> Microsoft.Deployment.WindowsInstaller.InstallerException: Cannot access session details from a non-immediate custom action 
    at Microsoft.Deployment.WindowsInstaller.Session.ValidateSessionAccess() 
    at Microsoft.Deployment.WindowsInstaller.Session.get_Item(String property) 
    at UnifiedAgentCustomActions.CustomActions.DeleteDirectory(Session session) 
    --- End of inner exception stack trace --- 
    at System.RuntimeMethodHandle.InvokeMethod(Object target, Object arguments, Signature sig, Boolean constructor) 
    at System.Reflection.RuntimeMethodInfo.UnsafeInvokeInternal(Object obj, Object parameters, Object arguments) 
    at System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object parameters, CultureInfo culture) 
    at Microsoft.Deployment.WindowsInstaller.CustomActionProxy.InvokeCustomAction(Int32 sessionHandle, String entryPoint, IntPtr remotingDelegatePtr) 

CustomAction Delete_Directory_Rollback返回实际的错误代码1603而将被转换为由于继续打标成功。

预期结果

The same CA is working during uninstall but during roll back it is not working.

它不起作用?请[编辑]您的问题给我们错误消息,预期的结果,实际结果等。 – YSC

你是在读/在自定义操作编写会话属性。 如果是,那么这可能是你的问题,如日志中所示。
