如果在同一棵树中多次使用 WiX DirectorySearch/@Depth 将被忽略

Question

我有一个 WiX 安装程序，可以将一堆扩展文件安装到另一个应用程序的应用程序目录中。为了确保文件最终出现在正确的位置，我使用了一堆嵌套的 DirectorySearch 来查找应用程序目录。

该应用程序通常安装在以下模式的路径中:

\Program Files (x86)\CompanyName\ProductName\[version]\[environment]\[optional intermediate folder]\AppFolderName

换句话说，常见的安装文件夹包括:

\Program Files (x86)\CompanyName\ProductName\1.0\Prod\AppFolderName
\Program Files (x86)\CompanyName\ProductName\1.1\Prod\OptionalFolderName\AppFolderName
\Program Files (x86)\CompanyName\ProductName\1.2\Test\AppFolderName
\Program Files (x86)\CompanyName\ProductName\1.2\Test\OptionalFolderName\AppFolderName

为了解决这个问题，我使用了一组嵌套的 DirectorySearch 元素来分配属性的路径。如果存在可选文件夹 (OptionalFolderName)，则以下操作有效:

<Property Id="SOMEAPPFOLDER">
  <DirectorySearch Id="ProgramFilesFolder" Path="[ProgramFilesFolder]">
    <DirectorySearch Id="CompanyNameFolder" Path="CompanyName">
      <DirectorySearch Id="ProductFolder" Path="ProductName">
          <DirectorySearch Id="EnvironmentFolder" Path="$(var.ENVIRONMENTNAME)" Depth="2">
            <DirectorySearch Id="OptionalIntermediateFolder" Path="OptionalFolderName">
              <DirectorySearch Id="AppFolder" Path="AppFolderName" AssignToProperty="yes">
                <FileSearch Id="AppNameExe" Name="AppName.exe" MinVersion="$(var.MIN_VERSION).0" MaxVersion="$(var.MAX_VERSION).999" />
              </DirectorySearch>
            </DirectorySearch>
        </DirectorySearch>
      </DirectorySearch>
    </DirectorySearch>
  </DirectorySearch>
</Property>

但是，由于 OptionalFolderName 是可选的，我想使用 DirectorySearch 来确定应用程序文件夹是直接位于环境文件夹下还是低一级。为了做到这一点，我将搜索树更改为:

<Property Id="SOMEAPPFOLDER">
  <DirectorySearch Id="ProgramFilesFolder" Path="[ProgramFilesFolder]">
    <DirectorySearch Id="CompanyNameFolder" Path="CompanyName">
      <DirectorySearch Id="ProductFolder" Path="ProductName">
        <DirectorySearch Id="EnvironmentFolder" Path="$(var.ENVIRONMENTNAME)" Depth="2">
          <DirectorySearch Id="AppFolder" Path="AppFolderName" Depth="2" AssignToProperty="yes">
            <FileSearch Id="AppNameExe" Name="AppName.exe" MinVersion="$(var.MIN_VERSION).0" MaxVersion="$(var.MAX_VERSION).999" />
          </DirectorySearch>
        </DirectorySearch>
      </DirectorySearch>
    </DirectorySearch>
  </DirectorySearch>
</Property>

但是，如果可选文件夹存在，则更高版本不起作用，但如果它不存在，则它起作用。换句话说，就好像忽略了深度属性之一；我的猜测是这是因为我在树的不同级别使用了两次 Depth 属性。

关于我如何解决这个问题的任何建议？

Answer 1

Depth的行为当FileSearch使用
Depth当 FileSearch 时工作方式不同是 DirectorySearch 的直系后代.

在正常情况下，Depth指定高于指定路径的最大文件夹级别数。但是，如果 FileSearch是直系后代，Depth指定在指定路径下查找文件的最大文件夹级别数。

换句话说，无法为作为文件的直接父级的目录指定深度。

示例

让我们看看你粘贴的代码:

<Property Id="SOMEAPPFOLDER">
  <DirectorySearch Id="ProgramFilesFolder" Path="[ProgramFilesFolder]">
    <DirectorySearch Id="CompanyNameFolder" Path="CompanyName">
      <DirectorySearch Id="ProductFolder" Path="ProductName">
        <DirectorySearch Id="EnvironmentFolder" Path="$(var.ENVIRONMENTNAME)" Depth="2">
          <DirectorySearch Id="AppFolder" Path="AppFolderName" Depth="2" AssignToProperty="yes">
            <FileSearch Id="AppNameExe" Name="AppName.exe" MinVersion="$(var.MIN_VERSION).0" MaxVersion="$(var.MAX_VERSION).999" />
          </DirectorySearch>
        </DirectorySearch>
      </DirectorySearch>
    </DirectorySearch>
  </DirectorySearch>
</Property>

在上面，第一次使用 Depth允许 ProductFolder 和 EnvironmentFolder 之间的两个目录级别，但第二次使用 Depth指的是 AppFolder之间的层数和 AppNameExe .

解决方法

以下 xml 使用两个搜索来解决该问题:

<!-- Locate the parent directory first -->
<Property Id="SOMEAPPFOLDER">
  <DirectorySearch Id="ProgramFilesFolder" Path="[ProgramFilesFolder]">
    <DirectorySearch Id="CompanyNameFolder" Path="CompanyName">
      <DirectorySearch Id="ProductFolder" Path="ProductName">
        <DirectorySearch Id="EnvironmentFolder" Path="$(var.ENVIRONMENTNAME)" Depth="1">
          <DirectorySearch Id="AppFolder" Path="AppFolderName" Depth="1" />
        </DirectorySearch>
      </DirectorySearch>
    </DirectorySearch>
  </DirectorySearch>
</Property>

<!-- Now, look for the file in the above directory -->
<Property Id="APPFILEEXISTS">
  <DirectorySearch Id="AppFolder" Path="SOMEAPPFOLDER">
    <FileSearch Id="AppNameExe" Name="AppName.exe" MinVersion="$(var.MIN_VERSION).0"
      MaxVersion="$(var.MAX_VERSION).999" />
  </DirectorySearch>
</Property>
