C# AssemblyFileVersion在程序中的使用

Question

我正在编写一个程序，并试图显示程序集文件版本

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

目前，这只返回"AssemblyVersion“中的前两个版本号，而不是”AssemblyFileVersion“。我真的很想引用AssemblyFileVersion，而不是存储一个名为"Version“的内部变量，我必须同时更新这个版本和程序集版本.

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

这是我的AssemblyFileVersion从AssemblyInfo.cs。我只想引用"3.5.x“部分，而不是"1.0.*”:/

谢谢，扎克

Answer 1

使用ProductMajorPart/ProductMinorPart代替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();
    }
