我需要在 .NET 2.0 C# 脚本中获取一些 JSON 输出。目标是使用一种方法来输出我需要的所有 JSON 提要。所有模型都具有相同的 id 和 name 属性，因此我有大约 15 个命名空间，它们在这里具有相同的部分。简而言之：因为我使用 castle，所以我可以调用该函数，如下所示：
/public/get_place_tags.castle
/public/get_place_types.castle
/public/get_place_whichEver.castle
城堡中哪个正在调用每个方法，即：get_place_tags(){}但我不想在可以调用一种方法来获取每种类型的输出的地方工作，如下所示：
/public/get_json.castle?wantedtype=place_types
有谁知道如何解决这一问题？
namespace campusMap.Controllers
{
[Layout("home")]
public class PublicController : BaseController
{
/* works and returns */
public void get_pace_type()
{
CancelView();
CancelLayout();
place_types[] types = ActiveRecordBase<place_types>.FindAll();
List<JsonAutoComplete> type_list = new List<JsonAutoComplete>();
foreach (place_types place_type in types)
{
JsonAutoComplete obj = new JsonAutoComplete();
obj.id = place_type.place_type_id;
obj.label = place_type.name;
obj.value = place_type.name;
type_list.Add(obj);
}
string json = JsonConvert.SerializeObject(type_list);
RenderText(json);
}
/* can;t ever find the namespace */
public void get_json(string wantedtype)
{
CancelView();
CancelLayout();
Type t = Type.GetType(wantedtype);
t[] all_tag = ActiveRecordBase<t>.FindAll();
List<JsonAutoComplete> tag_list = new List<JsonAutoComplete>();
foreach (t tag in all_tag)
{
JsonAutoComplete obj = new JsonAutoComplete();
obj.id = tag.id;
obj.label = tag.name;
obj.value = tag.name;
tag_list.Add(obj);
}
string json = JsonConvert.SerializeObject(tag_list);
RenderText(json);
}
}
}
[编辑]--（最新想法）运行时类型创建..我认为这是让它发挥作用的最干净的想法...-----
所以目标实际上是在运行时使用一种类型……对……所以我认为这会起作用。http://www.java2s.com/Code/CSharp/Development-Class/Illustratesruntimetypecreation.htm http://www.java2s.com/Code/CSharp/Development-Class/Illustratesruntimetypecreation.htm到目前为止，这是基于此的方法。我仍然遇到问题t克服错误
“无法找到类型或命名空间名称“t”（您是否缺少 using 指令或程序集引用？）”.. 不确定我在哪里出错了。似乎无法让它发挥作用，哈哈..
public void get_json(String TYPE)
{
CancelView();
CancelLayout();
if (String.IsNullOrEmpty(TYPE))
{
TYPE = "place_types";
}
// get the current appdomain
AppDomain ad = AppDomain.CurrentDomain;
// create a new dynamic assembly
AssemblyName an = new AssemblyName();
an.Name = "DynamicRandomAssembly";
AssemblyBuilder ab = ad.DefineDynamicAssembly(an, AssemblyBuilderAccess.Run);
// create a new module to hold code in the assembly
ModuleBuilder mb = ab.DefineDynamicModule("RandomModule");
// create a type in the module
TypeBuilder tb = mb.DefineType(TYPE, TypeAttributes.Public);
// finish creating the type and make it available
Type t = tb.CreateType();
t[] all_tag = ActiveRecordBase<t>.FindAll();
List<JsonAutoComplete> tag_list = new List<JsonAutoComplete>();
foreach (t tag in all_tag)
{
JsonAutoComplete obj = new JsonAutoComplete();
obj.id = tag.id;
obj.label = tag.name;
obj.value = tag.name;
tag_list.Add(obj);
}
RenderText(JsonConvert.SerializeObject(tag_list));
}
[编辑]--（较旧的想法）Eval 代码-----
因此，实现这一目标的尝试是使用反射和其他东西来基于此进行某种评估http://www.codeproject.com/script/Articles/ViewDownloads.aspx?aid=11939 http://www.codeproject.com/script/Articles/ViewDownloads.aspx?aid=11939
