我想使用自定义操作来设置属性，然后立即使用新设置的属性值来更新目录。到目前为止，我有一个自定义操作，它使用 WMI 查找单独产品的安装路径并将属性设置为该值。当我转身使用该属性来设置目录时，我得到的是旧的/默认值而不是新的属性值。

对于上下文：

我有一个这样的目录结构：

<Directory Id="TARGETDIR" Name="SourceDir">
   <Directory Id="ProgramFilesFolder" Name="pf">
     <Directory Id="CompanyName" Name="$(var.companyName)">
       <Directory Id="FooProductName" Name="$(var.prodName)">
         <Directory Id="INSTALL_DIR">
           <Directory Id="PRODUCT_ROOT">
         </Directory>
         <Directory Id="FOO_DIR" Name="NotInstalled">
           <Directory Id="FOO_BINDIR" Name="bin" />
         </Directory>
       </Directory>
     </Directory>
   </Directory>
</Directory>

我有这样声明的属性：

<Property Id="FOO_INSTALLLOCATION_CHECK_0" Value="AProductName" />
<Property Id="FOO_INSTALLLOCATION_DIR_0" Value="NotInstalledHere" />

我有这样声明的自定义操作：

<CustomAction Id="FooMoveFooDir" Directory="FOO_DIR" Value="[FOO_INSTALLLOCATION_DIR_0]" />
<CustomAction Id="GetInstallLocation" Return="check" BinaryKey="FooCAInstallLoc" DllEntry="GetInstallLocation" Execute="immediate" />

GetInstallLocation 使用 WMI 搜索包含 FOO_INSTALLLOCATION_CHECK_0 值的已安装产品，并将 FOO_INSTALLLOCATION_DIR_0 设置为该值。它实现了这一点在下面的日志片段中得到了证实。

我在 <InstallExecuteSequence> 中有以下内容

<Custom Action="FooMoveFooDir" After="CostFinalize">1</Custom>
<Custom Action="GetInstallLocation" Before="FooMoveFooDir">1</Custom>

日志记录看起来像这样（来自 WiLogUtil）：

它将目录 FOO_DIR 设置为 FOO_INSTALLLOCATION_DIR_0 的默认值，而不是在上一步中由自定义操作设置的值。搜索指示如何将目录设置为属性值以及如何使用 c# 中的自定义操作设置属性，但没有找到答案。

可能你已经尝试过了，但无论如何。与其使用自定义操作直接设置 DIrectory Id，不如通过属性设置值。

<Property Id="Foo_INSTALLDIR" /> 

<Directory Id="TARGETDIR" Name="SourceDir"> 

          <Directory Id="[Foo_INSTALLDIR]" Name="[Foo_INSTALLDIR]"> 

          </Directory>

</Directory>

看看我是如何使用目录*Id="[Foo_INSTALLDIR]"*

检查并告诉我！
