Question

我可以看到dll正在被调用，它是正确时间的正确入口点，但没有一个会话数据是空的。这让我疯了！

拜托，有人知道如何解决这个问题吗？

由于

这里是WIX定义

    <Binary Id="CustomActionBinary" SourceFile="$(var.BinariesForWix)blah.blah.CA.dll"  />

    <CustomAction Id="OptionsFileFound" Return="check" Property="OptionsFileFound.Get" Value="file=[OPTIONSPATH],version=[INSTALLVERSION],ADVANCED=[ADVANCED],parmsetting=OPTIONSEXIST"/>
    <CustomAction Id="OptionsFileFound.Get" BinaryKey="CustomActionBinary" DllEntry="OptionsFileFound" Execute="immediate" HideTarget="no" Return="check"/>  

    <InstallUISequence>
       <!-- check if installation configuration file is present -->
       <Custom Action ="OptionsFileFound.Get" After="MigrateFeatureStates"></Custom>
       <Custom Action ="AbortError" After="OptionsFileFound.Get">NOT(OPTIONSEXIST="yes")</Custom>
       <Custom Action ="InstallDatabaseList.Get" After="OptionsFileFound.Get"></Custom>
    </InstallUISequence>

现在是c＃代码

     [CustomAction]
    public static ActionResult OptionsFileFound(Session session)
    {
        FetchParms parmSet = new FetchParms(session);

        fileLocation = parmSet.GetActData("file");
        version = parmSet.GetActData("version");
        olympicInstall = parmSet.GetActData("advanced");

        session.Log(string.Format("*************************************************       Looking for options file at {0}, version number should be {1}", fileLocation, version));

        string parmSetting = parmSet.GetActData("parmsetting");

        if (File.Exists(fileLocation))
        {
            fileExists = true;
            session.Log("*************************************************                  found xml options file");
            LoadXmlToDictionary(fileLocation, session);
            session.Log("*************************************************                  loaded xml options file");
        }
        else
        {
            fileExists = false;
        }

        session[parmSetting] = fileExists ? "yes" : "no";

        parmSet.Dispose();
        parmSet = null;

        return ActionResult.Success;
    }

//在这里获取parms类

     public FetchParms(Session session)
    {
        session.Log("*************************************************  creating parameter dictionary");
        session.Log("*************************************************  session data = " + session.CustomActionData.Count.ToString());
        CustomActionData parmSets = session.CustomActionData;
        string parmString = parmSets.ToString();
        session.Log("************************************************* passed custom action data = " + session.CustomActionData.ToString());
        string[] eachParm = parmString.Split(new char[] { ';', ',' }, StringSplitOptions.RemoveEmptyEntries);

        foreach (string theParm in eachParm)
        {
            string[] theOptions = theParm.Split(new char[] { '=' });

            this.parmList.Add(theOptions[0], string.IsNullOrEmpty(theOptions[1]) ? string.Empty : theOptions[1]);
        }
    }

CustomActionData用于延迟自定义操作。延迟的自定义操作只能存在于InstallInitialize和InstallFinalize标准操作之间的InstallExecuteSequence中。试图在UI序列中使用它们是不正确的。

安装序列中的WIX自定义操作数据为空
