是否可以为AssemblyInfo.cs使用程序集属性添加信息,例如assembly:MyProjectAssembly,

因此,当 MEF 扫描 rutime 文件夹中的程序集时,它只会扫描那些用MyProjectAssembly.

我认为MEF没有这个功能。不过,我不是 100% 确定。

您可以做的是使用Mono.Cecil,它是 System.Reflection 的一个非常强大的替代品。Mono.Cecil允许您在不加载它们的情况下检查(和重写,但这是另一回事).NET 程序集。这意味着您可以轻松添加您正在寻找的功能。例如:

public static bool AssemblyIncludesCustomAttribute(string assemblyPath, string customAttributeName)
        {
            if (assemblyPath == null) throw new ArgumentNullException("assemblyPath");
            if (customAttributeName == null) throw new ArgumentNullException("customAttributeName");            

            AssemblyDefinition assemblyDef = AssemblyDefinition.ReadAssembly(assemblyPath);

            return assemblyDef.CustomAttributes.Any(ca => ca.AttributeType.FullName == customAttributeName);
        }

然后像这样使用它:

var catalog = new AggregateCatalog();
            string dirPath = @".\Extensions";
            foreach (string assemblyFile in Directory.EnumerateFiles(dirPath, "*.dll"))
            {
                if (AssemblyIncludesCustomAttribute("Blah.dll", "System.Reflection.AssemblyConfigurationAttribute"))
                {
                    catalog.Catalogs.Add(new AssemblyCatalog(assemblyFile));                    
                }
            }
