Question

如何投射反映出的结果从对象到List<TDynamicType>？

Type tSource = item.SourceType;     //enum
Type tDest = item.DestinationType;  //enum

MethodInfo method = typeof(EnumConverters).GetMethod("GetEnumValues");
MethodInfo methodGenericSource = method.MakeGenericMethod(tSource);
object enumsSource = methodGenericSource.Invoke(null, null);

// i need to convert enumsSource to List<tDest> (where tDest is enum)
List<tDest> list = ???

是否存在诸如“ getResultGeneric”或“ getResultOfType”之类的反射函数？

可以尝试像这样{@ {1}}

我已经解决了这一问题，将对象强制转换为iEnumerableOfInteger（以listOfObject广播为空），然后对其进行解析。

                Type tSource = item.SourceType;     //enum
                Type tDest = item.DestinationType;  //enum

                MethodInfo method = typeof(EnumConverters).GetMethod("GetEnumValues");
                MethodInfo methodGenericSource = method.MakeGenericMethod(tSource);
                object objEnumsSource = methodGenericSource.Invoke(null, null);

                //var listObj = (IEnumerable<object>)objEnumsSource;//throw
                var listInt = (IEnumerable<int>)objEnumsSource;
                foreach (var i in listInt)
                {
                    if (!Enum.IsDefined(tSource, i))
                        throw new ApplicationException($"!Enum.IsDefined({tSource.FullName}, {i})");

                    var o = Enum.ToObject(tSource, i);
                    var e = Convert.ChangeType(o, tSource);
                }

将对象的反射结果强制转换为list <TDest>，其中TDest是枚举
