In AssemblyInfo
there are two assembly versions:
AssemblyVersion
: Specify the version of the assembly being attributed.AssemblyFileVersion
: Instructs a compiler to use a specific version number for the Win32 file version resource. The Win32 file version is not required to be the same as the assembly's version number.I can get the Assembly Version
with the following line of code:
Version version = Assembly.GetEntryAssembly().GetName().Version;
But how can I get the Assembly File Version
?
This question is related to
c#
.net
assemblies
version
UPDATE: As mentioned by Richard Grimes in my cited post, @Iain and @Dmitry Lobanov, my answer is right in theory but wrong in practice.
As I should have remembered from countless books, etc., while one sets these properties using the [assembly: XXXAttribute]
, they get highjacked by the compiler and placed into the VERSIONINFO
resource.
For the above reason, you need to use the approach in @Xiaofu's answer as the attributes are stripped after the signal has been extracted from them.
public static string GetProductVersion() { var attribute = (AssemblyVersionAttribute)Assembly .GetExecutingAssembly() .GetCustomAttributes( typeof(AssemblyVersionAttribute), true ) .Single(); return attribute.InformationalVersion; }
(From http://bytes.com/groups/net/420417-assemblyversionattribute - as noted there, if you're looking for a different attribute, substitute that into the above)
Use this:
((AssemblyFileVersionAttribute)Attribute.GetCustomAttribute(
Assembly.GetExecutingAssembly(),
typeof(AssemblyFileVersionAttribute), false)
).Version;
Or this:
new Version(System.Windows.Forms.Application.ProductVersion);
When I want to access the application file version (what is set in Assembly Information -> File version), say to set a label's text to it on form load to display the version, I have just used
versionlabel.Text = "Version " + Application.ProductVersion;
This approach requires a reference to System.Windows.Forms
.
There are three versions: assembly, file, and product. They are used by different features and take on different default values if you don't explicit specify them.
string assemblyVersion = Assembly.GetExecutingAssembly().GetName().Version.ToString();
string assemblyVersion = Assembly.LoadFile("your assembly file").GetName().Version.ToString();
string fileVersion = FileVersionInfo.GetVersionInfo(Assembly.GetExecutingAssembly().Location).FileVersion;
string productVersion = FileVersionInfo.GetVersionInfo(Assembly.GetExecutingAssembly().Location).ProductVersion;
