在我的程序中,如何读取AssemblyInfo.cs中设置的属性:
[assembly: AssemblyTitle("My Product")]
[assembly: AssemblyDescription("...")]
[assembly: AssemblyConfiguration("")]
[assembly: AssemblyCompany("Radeldudel inc.")]
[assembly: AssemblyProduct("My Product")]
[assembly: AssemblyCopyright("Copyright @ me 2008")]
[assembly: AssemblyTrademark("")]
[assembly: AssemblyCulture("")]

我想向我的程序用户显示一些这些值,所以我想知道如何从主程序和我正在使用的komponent程序集加载它们.

这相当容易.你必须使用反射.您需要一个Assembly实例,它表示具有您要读取的属性的程序集.获得这个的简单方法是:
typeof(MyTypeInAssembly).Assembly

然后你可以这样做,例如:
object[] attributes = assembly.GetCustomAttributes(typeof(AssemblyProductAttribute), false);
AssemblyProductAttribute attribute = null;
if (attributes.Length > 0)
{
attribute = attributes[0] as AssemblyProductAttribute;
}

attribute.Product现在,引用将为您提供传递给AssemblyInfo.cs中的属性的值.当然,如果您查找的属性可能出现多次,您可能会在GetCustomAttributes返回的数组中获得多个实例,但这通常不是您希望检索的程序集级别属性的问题.

我创建了这个使用Linq的扩展方法:
public static T GetAssemblyAttribute<T>(this System.Reflection.Assembly ass) where T : Attribute
{
object[] attributes = ass.GetCustomAttributes(typeof(T), false);
if (attributes == null || attributes.Length == 0)
return null;
return attributes.OfType<T>().SingleOrDefault();
}

然后你就可以方便地使用它:
var attr = targetAssembly.GetAssemblyAttribute<AssemblyDescriptionAttribute>();
if(attr != null)
Console.WriteLine("{0} Assembly Description:{1}", Environment.NewLine, attr.Description);

好吧,对于原始问题,现在可能有点过时,但无论如何我将提供此信息以供将来参考.
如果要从程序集内部执行此操作,请使用以下命令:
using System.Runtime.InteropServices;
using System.Reflection;
object[] customAttributes = this.GetType().Assembly.GetCustomAttributes(false);

然后,您可以遍历所有自定义属性以查找所需的属性,例如
foreach (object attribute in customAttributes)
{
string assemblyGuid = string.Empty;
if (attribute.GetType() == typeof(GuidAttribute))
{
assemblyGuid = ((GuidAttribute) attribute).Value;
break;
}
}

好的,我试图通过许多资源找到一种方法来提取 .dll 文件的 .dll 属性Assembly.LoadFrom(path)。但不幸的是我找不到任何好的资源。这个问题是搜索的最高结果c# get assembly attributes(至少对我来说)所以我想分享我的工作。
经过数小时的努力,我编写了以下简单的控制台程序来检索常规程序集属性。我在这里提供了代码,以便任何人都可以将其用于进一步的参考工作。
我CustomAttributes为此使用财产。随意评论这种方法
代码 :
using System;
using System.Reflection;
namespace MetaGetter
{
class Program
{
static void Main(string[] args)
{
Assembly assembly = Assembly.LoadFrom("Path to assembly");
foreach (CustomAttributeData attributedata in assembly.CustomAttributes)
{
Console.WriteLine(" Name : {0}",attributedata.AttributeType.Name);
foreach (CustomAttributeTypedArgument argumentset in attributedata.ConstructorArguments)
{
Console.WriteLine(" >> Value : {0} \n" ,argumentset.Value);
}
}
Console.ReadKey();
}
}

示例输出:
Name : AssemblyTitleAttribute
>> Value : "My Product"

我个人非常喜欢lance Larsen 和他的静态 AssemblyInfo 类的实现。
一个人基本上将类粘贴到他的程序集中(我通常使用已经存在的 AssemblyInfo.cs 文件,因为它符合命名约定)
要粘贴的代码是:
internal static class AssemblyInfo
{
public static string Company { get { return GetExecutingAssemblyAttribute<AssemblyCompanyAttribute>(a => a.Company); } }
public static string Product { get { return GetExecutingAssemblyAttribute<AssemblyProductAttribute>(a => a.Product); } }
public static string Copyright { get { return GetExecutingAssemblyAttribute<AssemblyCopyrightAttribute>(a => a.Copyright); } }
public static string Trademark { get { return GetExecutingAssemblyAttribute<AssemblyTrademarkAttribute>(a => a.Trademark); } }
public static string Title { get { return GetExecutingAssemblyAttribute<AssemblyTitleAttribute>(a => a.Title); } }
public static string Description { get { return GetExecutingAssemblyAttribute<AssemblyDescriptionAttribute>(a => a.Description); } }
public static string Configuration { get { return GetExecutingAssemblyAttribute<AssemblyConfigurationAttribute>(a => a.Configuration); } }
public static string FileVersion { get { return GetExecutingAssemblyAttribute<AssemblyFileVersionAttribute>(a => a.Version); } }
public static Version Version { get { return Assembly.GetExecutingAssembly().GetName().Version; } }
public static string VersionFull { get { return Version.ToString(); } }
public static string VersionMajor { get { return Version.Major.ToString(); } }
public static string VersionMinor { get { return Version.Minor.ToString(); } }
public static string VersionBuild { get { return Version.Build.ToString(); } }
public static string VersionRevision { get { return Version.Revision.ToString(); } }
private static string GetExecutingAssemblyAttribute<T>(Func<T, string> value) where T : Attribute
{
T attribute = (T)Attribute.GetCustomAttribute(Assembly.GetExecutingAssembly(), typeof(T));
return value.Invoke(attribute);
}
}

您添加一个使用系统;到文件的顶部,你就可以开始了。
对于我的应用程序,我使用这个类来设置/获取/使用我的本地用户设置:
internal class ApplicationData
{
DirectoryInfo roamingDataFolder;
DirectoryInfo localDataFolder;
DirectoryInfo appDataFolder;
public ApplicationData()
{
appDataFolder = new DirectoryInfo(Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData), AssemblyInfo.Product,"Data"));
roamingDataFolder = new DirectoryInfo(Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData),AssemblyInfo.Product));
localDataFolder = new DirectoryInfo(Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData), AssemblyInfo.Product));
if (!roamingDataFolder.Exists)
roamingDataFolder.Create();
if (!localDataFolder.Exists)
localDataFolder.Create();
if (!appDataFolder.Exists)
appDataFolder.Create();
}
/// <summary>
/// Gets the roaming application folder location.
/// </summary>
/// <value>The roaming data directory.</value>
public DirectoryInfo RoamingDataFolder => roamingDataFolder;
/// <summary>
/// Gets the local application folder location.
/// </summary>
/// <value>The local data directory.</value>
public DirectoryInfo LocalDataFolder => localDataFolder;
/// <summary>
/// Gets the local data folder location.
/// </summary>
/// <value>The local data directory.</value>
public DirectoryInfo AppDataFolder => appDataFolder;
}

看看 Larsens 网站 (MVP),他有很酷的东西可以从中汲取灵感。
