程序集getTypeInfo上的CustomAttribute错误

Question

我有一个c＃静态类：

public static class AssStaticHelp
    {

        static private List<Type> Tipi=new List<Type>();
        public static string searchManagerMethod = @"C:\StoredWeb\StoredWeb\searchManagerMethod";

        public static List<Type> GetTipi()
        {
            AppDomain currDomain = AppDomain.CurrentDomain;
            currDomain.ReflectionOnlyAssemblyResolve += new ResolveEventHandler(HandlerMethodTipi);

            if (currDomain.ReflectionOnlyGetAssemblies().Length == 0)
                Tipi = new List<Type>();

            if (Tipi.Count == 0) {
                currDomain.ReflectionOnlyAssemblyResolve += new ResolveEventHandler(HandlerMethodTipi);
                DirectoryInfo di = new DirectoryInfo(searchManagerMethod);
                foreach (FileInfo f in di.GetFiles("*.dll"))
                {
                    Assembly ass = Assembly.ReflectionOnlyLoadFrom(f.FullName);
                    Type[] listType = ass.GetTypes();
                    if (listType.Length > 0)
                    {
                        Tipi.AddRange(listType);
                    }
                }

            }

            return Tipi;
        }


        private static Assembly HandlerMethodTipi(object sender, ResolveEventArgs args)
        {
            AssemblyName assName = new AssemblyName(args.Name);
            string fileName = Path.GetFullPath(searchManagerMethod + "\\" + assName.Name + ".dll");
            if (File.Exists(fileName))
            {

                return Assembly.ReflectionOnlyLoadFrom(fileName);
            }
            return Assembly.ReflectionOnlyLoad(args.Name);
        }

基本上它加载了一些我需要在设置自定义属性（SialBaseType）时探索的程序集，如下所示：

[Serializable]
    [SialBaseType("SialMinBaseType", true)]
    public abstract class SialMinBaseType : BEBase
    {
        #region Property
        /// <summary>
        /// Identificativo univoco dell'oggetto
        /// </summary>
        public string Id { get; set; }
...

问题是有时候我可以获得自定义属性数据，有时候不会...而且我无法弄清楚为什么......

在这种情况下：

1）纠正一个：

2）问题给了我＆＃34;找不到方法：＆＃39; Void NETA.SUITE.SIAL.Tipi.Base.SialBaseTypeAttribute..ctor（System.String）＆＃39;。＆＃34;。 ;：
