阅读AssemblyFileVersion从集信息后编译 [英] Read AssemblyFileVersion from AssemblyInfo post-compile
问题描述
如何才能阅读的 AssemblyFileVersion 的，或者它的组件的 AssemblyFileMajorVersion 的 AssemblyFileMinorVersion 的 AssemblyFileBuildNumber 的 AssemblyFileRevision 的，在.csproj的范围内，以下编译？
How can one read the AssemblyFileVersion, or its components AssemblyFileMajorVersion, AssemblyFileMinorVersion, AssemblyFileBuildNumber, AssemblyFileRevision, within the .csproj, following compilation?
我试图从内置组件拉动信息如下：
I have tried the following which pulls the information from the built assembly:
<Target Name="AfterCompile">
<GetAssemblyIdentity AssemblyFiles="$(TargetPath)">
<Output
TaskParameter="Assemblies"
ItemName="MyAssemblyIdentities"/>
</GetAssemblyIdentity>
<Message Text="AssemblyVersion = %(MyAssemblyIdentities.Version)" />
</Target>
但是，检索的的AssemblyVersion 的而不是 AssemblyFileVersion 的。似乎没有成为后者的一个记录的元数据项。我也尝试过：
But that retrieves the AssemblyVersion and not the AssemblyFileVersion. There does not seem to be a documented metadata entry for the latter. I also tried:
<Import Project="$(MSBuildExtensionsPath)\ExtensionPack\MSBuild.ExtensionPack.tasks" />
<Target Name="AfterCompile">
<MSBuild.ExtensionPack.Framework.Assembly TaskAction="GetInfo" NetAssembly="$(TargetPath)">
<Output TaskParameter="OutputItems" ItemName="Info" />
</MSBuild.ExtensionPack.Framework.Assembly>
<Message Text="AssemblyFileVersion = %(Info.FileVersion)" />
</Target>
不幸的是，虽然这检索正确的值，它也文件锁组件，直到VS2008被关闭。
Unfortunately, while this retrieves the correct value, it also file locks the assembly until VS2008 is closed.
坦率地说，也不是我想要的，我宁愿读直接从AssemblyInfo.cs中的信息。不过，我无法弄清楚如何做到这一点。我以为程序集信息的MSBuild的扩展是一个办法，但似乎侧重于书面形式向集信息，而不是从它检索值。
Frankly, neither is what I want as I would rather read the information from the AssemblyInfo.cs directly. However, I cannot figure out how to do that. I assumed AssemblyInfo in the MSBuild Extensions was one way, but it seems focused on writing to the AssemblyInfo and not retrieving values from it.
我怎样才能最好地实现这一点？

推荐答案
我已经成功这个使用自定义任务来解决。类库DLL是因为这样（有些code调整/消除了简洁）：
I've managed to solve this using a custom task. The class library DLL is as so (some code adjusted/eliminated for brevity):
using System;
using System.IO;
using System.Text.RegularExpressions;
using Microsoft.Build.Framework;
namespace GetAssemblyFileVersion
{
public class GetAssemblyFileVersion : ITask
{
[Required]
public string strFilePathAssemblyInfo { get; set; }
[Output]
public string strAssemblyFileVersion { get; set; }
public bool Execute()
{
StreamReader streamreaderAssemblyInfo = null;
Match matchVersion;
Group groupVersion;
string strLine;
strAssemblyFileVersion = String.Empty;
try
{
streamreaderAssemblyInfo = new StreamReader(strFilePathAssemblyInfo);
while ((strLine = streamreaderAssemblyInfo.ReadLine()) != null)
{
matchVersion = Regex.Match(strLine, @"(?:AssemblyFileVersion\("")(?<ver>(\d*)\.(\d*)(\.(\d*)(\.(\d*))?)?)(?:""\))", RegexOptions.IgnoreCase | RegexOptions.IgnorePatternWhitespace | RegexOptions.Singleline | RegexOptions.ExplicitCapture);
if (matchVersion.Success)
{
groupVersion = matchVersion.Groups["ver"];
if ((groupVersion.Success) && (!String.IsNullOrEmpty(groupVersion.Value)))
{
strAssemblyFileVersion = groupVersion.Value;
break;
}
}
}
}
catch (Exception e)
{
BuildMessageEventArgs args = new BuildMessageEventArgs(e.Message, string.Empty, "GetAssemblyFileVersion", MessageImportance.High);
BuildEngine.LogMessageEvent(args);
}
finally { if (streamreaderAssemblyInfo != null) streamreaderAssemblyInfo.Close(); }
return (true);
}
public IBuildEngine BuildEngine { get; set; }
public ITaskHost HostObject { get; set; }
}
}
和在项目文件：
<UsingTask AssemblyFile="GetAssemblyFileVersion.dll" TaskName="GetAssemblyFileVersion.GetAssemblyFileVersion" />
<Target Name="AfterCompile">
<GetAssemblyFileVersion strFilePathAssemblyInfo="$(SolutionDir)\AssemblyInfo.cs">
<Output TaskParameter="strAssemblyFileVersion" PropertyName="strAssemblyFileVersion" />
</GetAssemblyFileVersion>
<Message Text="AssemblyFileVersion = $(strAssemblyFileVersion)" />
</Target>
我测试过这一点，如果你使用的 MSBuild.ExtensionPack.VersionNumber.targets 的用于自动版本将读取更新后的版本。
I've tested this and it will read the updated version if you use MSBuild.ExtensionPack.VersionNumber.targets for auto-versioning.
显然，这可以很容易地扩展，使得一个正则表达式被从项目文件传递到更通用的定义任务，以获得在任何文件中的任何匹配。
更新2009/09/03：
Obviously, this could be easily extended so that a regex is passed from the project file to a more general-purpose custom task in order to obtain any match in any file.
Update 2009/09/03:
一个额外的变化有可能作出让每个版本的 ApplicationVersion 更新。 InitialTargets =AfterCompile必须被添加到＆LT;项目... 。这是<一个href="http://social.msdn.microsoft.com/Forums/en-US/msbuild/thread/c1a2f4af-1297-4577-8d4b-7b1abe40d768">solved由晁适。
One additional change has to be made to make the ApplicationVersion update on each build. InitialTargets="AfterCompile" must be added to the <Project.... This was solved by Chao Kuo.
