程序中的C＃AssemblyFileVersion用法

Question

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

Answer 1

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);
        }
    }

Answer 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 ());

    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();
    }

Answer 4

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.

Answer 5

我想你将不得不使用FileVersionInfo类。

System.Diagnostics.FileVersionInfo.GetVersionInfo(FullpathToAssembly)

Answer 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************
