C# AssemblyFileVersion usage within a program

问题

I'm working on a program, and I'm trying to display the assembly FILE version

    public static string Version
    {
        get
        {
            Assembly asm = Assembly.GetExecutingAssembly();
            FileVersionInfo fvi = FileVersionInfo.GetVersionInfo(asm.Location);
            return String.Format("{0}.{1}", fvi.FileMajorPart, fvi.FileMinorPart);
        }
    }

At the moment, this only returns the first two version numbers in the "AssemblyVersion", not "AssemblyFileVersion." I'd really like to just reference the AssemblyFileVersion rather than store an internal variable called "Version" that I have to update both this and the assembly version...

[assembly: AssemblyVersion("1.0.*")]
[assembly: AssemblyFileVersion("3.5.0")]

That's my AssemblyFileVersion from AssemblyInfo.cs. I'd like to just reference the "3.5.x" part, not the "1.0.*" :/

Thanks, Zack

Use ProductMajorPart/ProductMinorPart instead of FileMajorPart/FileMinorPart :

    public static string Version
    {
        get
        {
            Assembly asm = Assembly.GetExecutingAssembly();
            FileVersionInfo fvi = FileVersionInfo.GetVersionInfo(asm.Location);
            return String.Format("{0}.{1}", fvi.ProductMajorPart, fvi.ProductMinorPart);
        }
    }

回答2:

using System.Reflection;
using System.IO;

FileVersionInfo fv = System.Diagnostics.FileVersionInfo.GetVersionInfo(Assembly.GetExecutingAssembly().Location);

Console.WriteLine("AssemblyVersion : {0}", Assembly.GetExecutingAssembly().GetName().Version.ToString());

Console.WriteLine ("AssemblyFileVersion : {0}" , fv.FileVersion.ToString ());

回答3:

    var fileVersion = GetCustomAttributeValue<AssemblyFileVersionAttribute>(assembly, "Version");

    private static string GetCustomAttributeValue<T>(Assembly assembly, string propertyName)
        where T : Attribute
    {
        if (assembly == null || string.IsNullOrEmpty(propertyName)) return string.Empty;

        object[] attributes = assembly.GetCustomAttributes(typeof(T), false);            
        if (attributes.Length == 0) return string.Empty;

        var attribute = attributes[0] as T;
        if (attribute == null) return string.Empty;

        var propertyInfo = attribute.GetType().GetProperty(propertyName);
        if (propertyInfo == null) return string.Empty;

        var value = propertyInfo.GetValue(attribute, null);
        return value.ToString();
    }

To get the version of the currently executing assembly you can use:

using System.Reflection;
Version version = Assembly.GetExecutingAssembly().GetName().Version;

The Assembly class can also load files and access all the assemblies loaded in a process.

回答5:

I guess you will have to use FileVersionInfo class.

System.Diagnostics.FileVersionInfo.GetVersionInfo(FullpathToAssembly)

回答6:

 protected void Application_Start(object sender, EventArgs e)
 {
     _log.InfoFormat("*************{0} **** Version: {1}************  ", Assembly.GetExecutingAssembly().GetName().Name, Assembly.GetExecutingAssembly().GetName().Version);
  }

Output

INFO Global - *************CustomerFile **** Version: 1.0.17.2510************
