unity 2019.4.40f1 反射 GetCustomAttribute nunit.framework.dll 找不到报错

因为反射的 Type 里面包含了像 JetBrains.Rider 的类型，这类类型获取 attribute 的时候需要找高版本的 nunit.framework 导致报错，故遍历程序集 Type 时要过滤掉这些 Type

       public static List<Type> SafeGetTypes()
            var type_list = new List<Type>();
            var asm_list = AppDomain.CurrentDomain.GetAssemblies();
            foreach (var asm in asm_list)
                    type_list.AddRange(asm.GetTypes()
                        .Where( x =>
                            var nameSpace = x.Namespace;
                            return nameSpace == null
                                   // JetBrains.Rider 的类型引用高版本 nunit，导致获取 attribute 时报错
                                   || !nameSpace.StartsWith("JetBrains.Rider", StringComparison.Ordinal);
                catch (ReflectionTypeLoadException ex)
                    var sb = new StringBuilder();
                    sb.AppendFormat("加载类型失败! asm:{0}\n", asm);
                    foreach (var e2 in ex.LoaderExceptions)
                        sb.AppendFormat("  loader 错误: {0}\n", e2.Message);
                        if (e2 is FileNotFoundException e3)
                            sb.AppendFormat("    Fusion Log: {0}\n", e3.FusionLog);
                    Debug.LogError(sb.ToString());
            return type_list;
