Re: [Nant-users] get version from dll?

[Ian MacLean]

It could be that it doesn't like the UNC path. It worked frin for me 
with a local path. Try copying that code into a small c# console app and 
you'll get the full exception information.

From the looks of it we aren't propagating that exception to the user 
when a function fails. Jarek, is that the case ?

OK... so what am I doing wrong... I get the following error:

I tried it with an without escaping the back slashes. Here is the
relevant portion from my build file:

actually you can set the properties from the function as well. Like:

<script language="C#" prefix="script" >
   <code><![CDATA[                
     
       [Function("get-file-version")]
       public string GetFileVersion( string file, bool setProperties )
{
              
       System.Diagnostics.FileVersionInfo myFileVersionInfo =
           System.Diagnostics.FileVersionInfo.GetVersionInfo(file);
           if ( setProperties ) {
               Project.Properties["dll.majorversion"] = 
myFileVersionInfo.FileMajorPart.ToString();
               Project.Properties["dll.minorversion"] = 
myFileVersionInfo.FileMinorPart.ToString();
               Project.Properties["dll.buildversion"] = 
myFileVersionInfo.FileBuildPart.ToString();
               Project.Properties["dll.privateversion"] = 
myFileVersionInfo.FilePrivatePart.ToString();
           }
           return myFileVersionInfo.FileVersion;
      
       }
    
]]></code>
</script>

the advantage of a custom function over a block of script in a target is

that you only have to define it once and can then call it for each file 
you need version info for.

This is nice. Better than my assembly specific version.

Note that if you are using a current nightly you can wrap your 
diagnostics code in a custom function definition like:

<code><![CDATA[                  [Function("get-file-version")]
      public string GetFileVersion( string file ) {
                      System.Diagnostics.FileVersionInfo 
myFileVersionInfo =
           System.Diagnostics.FileVersionInfo.GetVersionInfo(file);
       return myFileVersionInfo.FileVersion;
    }
]]></code>
</script>
and then call it like:

<property name="fileversion" 
value="script::get-file-version('somefile.dll')" />

of course if you need to set properties to the individual version 
components then a custom task is a better option.

Bob,
You should be able to drop the above code into your build file if all 
you need is the file version as a string.

How about something like this? (off the top of my head and without
intellisense :)
We've done something similar here - for checking which versions of 
files are
installed etc - had to do it all in script - I've given up on writing
     

 

custom
tasks, they take too long to edit when you need to change stuff :)
<script language="C#">
 <code><![CDATA[
  public static void ScriptMain(Project project)
  {
    System.Diagnostics.FileVersionInfo myFileVersionInfo =
System.Diagnostics.FileVersionInfo.GetVersionInfo("path to your
     

dll");
 

    project.Properties["dll.majorversion"] =
myFileVersionInfo.FileMajorPart;
    project.Properties["dll.minorversion"] =
myFileVersionInfo.FileMinorPart;
    project.Properties["dll.buildversion"] =
myFileVersionInfo.FileBuildPart;
    project.Properties["dll.privateversion"] =
myFileVersionInfo.FilePrivatePart;

Subject: [Nant-users] get version from dll?


Hi All,



I am creating a build script that deploys our last successful daily 
build to
our QA machine.

How could I get the version/build number from a dll? Any ideas? I 
could get
the last build number from the build number file that my version task
     

 

uses,
however, if that build failed it will not be the one in the daily
     

build
 

area.



Thanks,

Bob
