新的一天,新的问题;-)仍然需要与自定义的行动斗争.我已经管理它来调用自定义操作并将一些测试数据传递给它.现在我想用我需要的真实数据替换testdata.这里的问题开始：我想调用一个批处理文件,它被安装在我的安装的子目录中.因此,我需要将安装路径传递给自定义操作. Afaik这可以使用customactiondata机制来完成.但这不行.当我记录安装时,我可以看到,在定制操作INSTALLLOCATION之外指向正确的路径,但是一旦我查看customaction,customactiondata属性是空的…

任何人都可以看看我的代码,并给我一个提示我做错了什么？感谢你的好意！

调用自定义操作的合并模块：

<Module Id="DflHelpInstaller" Language="1033" Version="1.0.0.0">
    <Package Id="f952de58-1dc6-46b3-872a-7a49e2d9ea0a" Manufacturer="DflHelpInstaller" InstallerVersion="200" />

<Binary Id='RegisterDflHelpDll' SourceFile="$(var.REGISTERHELP.TargetDir)RegisterDflHelp.CA.dll" />

    <CustomAction Id='RegisterDflHelp' BinaryKey='RegisterDflHelpDll'  DllEntry='RegisterDflHelp' Execute='deferred' />

    <CustomAction Id="RegisterDflHelp.SetProperty" Return="check" Property="RegisterDflHelp" Value='[INSTALLLOCATION]' Execute='immediate' />


    <InstallExecuteSequence>
      <Custom Action='RegisterDflHelp.SetProperty' After='CostFinalize' />
      <Custom Action='RegisterDflHelp' After='InstallFiles' />
    </InstallExecuteSequence>

    <Directory Id="TARGETDIR" Name="SourceDir">
        </Directory>
    <ComponentGroupRef Id="HelpGroup"/>

    </Module>
</Wix>

使用MergeModule的安装程序的大纲：

    </Component>
    <Merge Id ="DflHelpInstaller" SourceFile="DflHelpInstaller.msm" Language="1033" DiskId="1" />
      </Directory>
</Directory>

CustomAction：

public class CustomActions
   { 
        [CustomAction]
        public static ActionResult RegisterDflHelp(Session session)
        {
            session.Log("Begin CustomAction1");
            session.Log("Before Access to customactiondata");

            //should contain the installation path - unfortunatelly it is empty! why?
            string cad = session["CustomActionData"];
            Debugger.Break();


            RegisterHelp(cad);

            session.Log("End of custom action..");
            return ActionResult.Success;
        }

<CustomAction Id="MyCustomActionData" Return="check" Property="MyCustomAction" Value='PROPERTY0=[PROPERTY0];PROPERTY1=[PROPERTY1];PROPERTY2=[PROPERTY2]' Execute='immediate' />

string property0 = session.CustomActionData["Property0"];
string property1 = session.CustomActionData["Property1"];
string property2 = session.CustomActionData["Property2"];

<CustomAction Id="RegisterDflHelp.SetProperty" Return="check" Property="RegisterDflHelp" Value='INSTALLLOCATION=[INSTALLLOCATION]' Execute='immediate' />

string cad = session.CustomActionData["INSTALLLOCATION"];
