Question

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，使用WMI查找单独产品的安装路径，并将属性设置为该值。当我转身并使用该属性设置目录时，我得到旧的/默认值而不是新的属性值。

上下文：

我有一个像这样的目录结构：

<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>

我声明的属性如下：

<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中值的已安装产品，并将FOO_INSTALLLOCATION_DIR_0设置为该值。它完成了这一点在下面的日志记录片段中得到证实。

我在＆lt; InstallExecuteSequence＆gt;

中有以下内容

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

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，而不是前一步骤中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。

Answer 1

可能你已经尝试过了，但无论如何。不是使用自定义操作直接设置DIrectory Id，而是通过属性设置值。

<Property Id="Foo_INSTALLDIR" /> 

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

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

          </Directory>

</Directory>

了解我如何使用目录 * Id =“[Foo_INSTALLDIR]”*

检查并告诉我们！

设置目录的Wix自定义操作使用默认值而不是先前自定义操作中设置的值
