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app目录中.为了确保文件最终位于正确的位置,我使用一堆嵌套的DirectorySearch来查找app目录.

该应用程序通常安装在此模式之后的路径中：

Program Files (x86)CompanyNameProductName[version][environment][optional intermediate folder]AppFolderName

换句话说,常见的安装文件夹包括：

Program Files (x86)CompanyNameProductName1.0ProdAppFolderName
Program Files (x86)CompanyNameProductName1.1ProdOptionalFolderNameAppFolderName
Program Files (x86)CompanyNameProductName1.2TestAppFolderName
Program Files (x86)CompanyNameProductName1.2TestOptionalFolderNameAppFolderName

为了解决这个问题,我使用一组嵌套的DirectorySearch元素来分配Property的路径.如果存在可选文件夹(OptionalFolderName),则以下内容有效：

<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app文件夹是直接位于环境文件夹下还是一个级别.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,如果存在可选文件夹,则后一版本不起作用,但如果不存在则它可以正常工作.换句话说,就好像其中一个Depth属性是isgnored;我的猜测是因为我在树中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？

更新 – 从msiexec / i添加日志片段摘录[msiname] / l * v [logfile]：

解决方法

使用FileSearch时的深度行为

当FileSearch是DirectorySearch的直接后代时,深度的工作方式不同.

在正常情况下,Depth指定指定路径上方的最大文件夹级别数.但是,如果FileSearch是直接后代,则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,没有办法指定作为文件的直接父级的目录的深度.

例

我们来看看你粘贴的代码：

<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允许在ProductFolder和EnvironmentFolder之间有两个目录级别,但第二次使用Depth是指AppFolder和AppNameExe之间的级别数.

解决方法

以下xml使用两个搜索来解决此问题：

<!-- 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>
