Question

是否有一种更简洁的方法可以使用反射获得列表计数呢？

 Boolean include = false;

 foreach (PropertyInfo item in props)
        {
            var pt = item.PropertyType;                

            String listType = pt.GetGenericArguments()[0].Name;

             // Is there a better solution than this?
             switch (listType)
                            {
                                case "jsonResult":
                                    var list = v as List<jsonResult>;

                                    include =  list.count > 0;
                                    break;                                
                            }
        }
    )

我尝试了谷歌搜索的各种想法，但没有运气。

我并不完全明白什么是＆＃34; v＆＃34;变量，但如果它是一个对象，当它是一个你想要计算的集合时，你可以这样做：

private static int? GetCount(object @object)
{
    var collection = @object as ICollection;
    if (collection == null)
        return null;

    return collection.Count;
}

＆＃34; GetCount＆＃34;方法：
