（我可以/我如何）从 WiX 访问程序集信息

Question

我正在学习如何使用 WiX 为我的项目创建安装程序，并且希望能够引用我的 VS2019 C# 项目的程序集信息，这些信息是从我的 .wxs 文件中的项目属性 > 应用程序 > 程序集信息按钮填充的.

我知道我可以使用添加项目作为参考，然后使用$(var.MyProject.???) 声明，但我不知道在哪里可以找到项目的可行点符号属性列表。或者我知道我可以使用 '' 和 <Package Manufacturer="$(var.CompanyName)" .../> 来省去多次输入数据的麻烦，但我仍然希望将它从项目中拉出来并放在一个地方。

谢谢

SEO 术语：wix 汇编版本。 wix 程序集信息

Answer 1

Light.exe：在此处查看 WiX light.exe 文档：https://wixtoolset.org/documentation/manual/v3/overview/light.html#standard-binder-variables

如果您想将主程序集的版本作为设置的 ProductVersion 运行，您应该可以这样做：

<Product Id="*" Name="MyProject" Version="!(bind.fileVersion.MyMain.exe)"
         Manufacturer="MyCorp" Language="1033" UpgradeCode="PUT-GUID-HERE">

 <..>

  <Component Feature="Main">
    <File Id="MyMain.exe" Source="MyMain.exe"></File>
  </Component>

WiX 示例：Complete Github.com sample here。

fileLanguage 和 fileVersion 可用于所有版本化的二进制文件。 Dot NET 程序集支持许多其他变量 - see documentation（与答案顶部的链接相同）。

Rob Mensching：WiX creator Mensching has an answer here。 本质："You can drive your product version off of an assembly's version using "!(bind.assemblyVersion.FileId)". ... You can only specify binder variables in .wxs files. It's a binder (in light.exe) concept not an MSBuild (in MSBuild.exe reading .wixproj files) concept"

Heath Stewart：请查看此博客以获取有关 .NET 程序集值的一些信息： https://devblogs.microsoft.com/setup/get-binder-variables-for-assemblies-without-installing-into-the-gac/ - 本质："...to get binder variables for assemblies without installing into the GAC set File/@Assembly to “.net” or “win32”, then for the same file set File/@AssemblyApplication to the value for File/@Id"

Answer 2

对于那些将来遇到这种情况的人，这里是从 wix 访问程序集信息的方法。

请注意，在发帖时我没有设法将整个数据对象作为单个结构返回，但至少可以将值输出为字符串。

为了便于定义目标程序集文件，请通过 .wixproj 文件中的节点或通过 wixProj 的 Properties > Build > Define Preprocessor variables 字段定义一个常量： AssetPath=../MyReferencedProject/bin/$(Configuration)/MyAsset.exe;

接下来，将以下代码放入您的 .wixProj 文件中。 （用 NotePad++ 编辑，然后在 VS 中重新加载项目）

    <!--To modify your build process, add your task inside one of the targets below and uncomment it.
    Other similar extension points exist, see Wix.targets.-->

    <Target Name="BeforeBuild">
        <ExtractAsmInfo AsmPath="$([System.Text.RegularExpressions.Regex]::Match(&quot;;$(DefineConstants);&quot;, &quot;;AssetPath=(?&lt;path&gt;.*?);&quot;).Groups[&quot;path&quot;].Value)">
            <Output PropertyName="asmCompName" TaskParameter="AsmCompName" />
            <Output PropertyName="asmProdName" TaskParameter="AsmProdName" />
            <Output PropertyName="asmDesc" TaskParameter="AsmDesc" />
            <Output PropertyName="asmCopyright" TaskParameter="AsmCopyright" />
            <Output PropertyName="asmTrademarks" TaskParameter="AsmTrademarks" />
            <Output PropertyName="asmFileVersion" TaskParameter="AsmFileVersion" />
        </ExtractAsmInfo>

        <!--This is needed for the output to be accessible from your .wxs file as "!(wix.asmCompName)"-->
        <CreateProperty Value="asmCompName=$(asmCompName);$(WixVariables)">
            <Output TaskParameter="Value" PropertyName="WixVariables" />
        </CreateProperty>
        <CreateProperty Value="asmProdName=$(asmProdName);$(WixVariables)">
            <Output TaskParameter="Value" PropertyName="WixVariables" />
        </CreateProperty>
        <CreateProperty Value="asmDesc=$(asmDesc);$(WixVariables)">
            <Output TaskParameter="Value" PropertyName="WixVariables" />
        </CreateProperty>
        <CreateProperty Value="asmCopyright=$(asmCopyright);$(WixVariables)">
            <Output TaskParameter="Value" PropertyName="WixVariables" />
        </CreateProperty>
        <CreateProperty Value="asmTrademarks=$(asmTrademarks);$(WixVariables)">
            <Output TaskParameter="Value" PropertyName="WixVariables" />
        </CreateProperty>
        <CreateProperty Value="asmFileVersion=$(asmFileVersion);$(WixVariables)">
            <Output TaskParameter="Value" PropertyName="WixVariables" />
        </CreateProperty>
    </Target>

    <!--<Target Name="AfterBuild"></Target>-->

    <!--Extracts data from the assembly-->
    <UsingTask TaskName="ExtractAsmInfo" TaskFactory="CodeTaskFactory" AssemblyFile="$(MSBuildToolsPath)\Microsoft.Build.Tasks.Core.dll">
        <ParameterGroup>
            <!--The assembly path-->
            <AsmPath ParameterType="System.String" Required="true" />
            <!--The return value. Note the return types are extremely limited-->
            <AsmCompName ParameterType="System.String" Output="true" />
            <AsmProdName ParameterType="System.String" Output="true" />
            <AsmDesc ParameterType="System.String" Output="true" />
            <AsmCopyright ParameterType="System.String" Output="true" />
            <AsmTrademarks ParameterType="System.String" Output="true" />
            <AsmFileVersion ParameterType="System.String" Output="true" />
        </ParameterGroup>
        <Task>
            <Reference Include="System.Xml" />
            <Reference Include="System.Xml.Linq" />
            <Using Namespace="System" />
            <Using Namespace="System.Xml.Linq" />
            <Using Namespace="System.Reflection" />
            <Using Namespace="System.Diagnostics" />
            <Code Type="Fragment" Language="cs">
                <![CDATA[
            FileVersionInfo fileInfo = FileVersionInfo.GetVersionInfo(AsmPath);
            AsmCompName = fileInfo.CompanyName;
            AsmProdName = fileInfo.ProductName;
            AsmDesc = fileInfo.FileDescription;
            AsmCopyright = fileInfo.LegalCopyright;
            AsmTrademarks = fileInfo.LegalTrademarks;
            AsmFileVersion = fileInfo.FileVersion;
        ]]>
            </Code>
        </Task>
    </UsingTask>

最后，在您的 .wxs 文件中，您可以使用：

<!--Note the use of an EXCLAMATION MARK and not Dollar Sign as well as the wix. instead of var.-->
!(wix.asmProdName)
!(wix.asmCompName)
!(wix.asmDesc)
!(wix.asmCopyright)
!(wix.asmTrademarks)
!(wix.asmFileVersion)

<!--Example-->
<Product Id="*" UpgradeCode="1129c4e2-e288-48d5-84dd-587aec927f26"
             Name="!(wix.asmProdName) Installer" Manufacturer="!(wix.asmCompName)"
             Language="1033" Version="!(wix.asmFileVersion)">

        <Package Id="*" Compressed="yes"
                 InstallerVersion="200" InstallPrivileges="elevated" InstallScope="perMachine"
                 Keywords="Installer" Languages="1033" Platform="x64" ReadOnly="no" ShortNames="no" SummaryCodepage="1252"
                 Description="The !(wix.asmDesc) and it's protocol installer."
                 Comments="!(wix.asmCopyright) | !(wix.asmTrademarks)" />
...
</Product>
