我想存儲一些通用函數以供稍後執行。問題出現在關於函數的論點上。對於不同的類型，我想創建和存儲相同的泛型函數委託，但我不能這樣做。下面是我的版本獲取函數的類;存儲函數模板
public delegate void CGTaskHandler1<T>(T value) where T : IControllerBase;
public class CGTask
{
private CGTaskHandler1<IControllerBase> Aksiyon;
private IControllerBase param;
public void RegisterCGTask(CGTaskHandler1<IControllerBase> aFunc, IControllerBase aParam)
{
Aksiyon = aFunc;
param = aParam;
}
public void ExecuteCGTask()
{
try
{
Aksiyon(param);
}
catch (Exception ex)
{
Logger.SetLog("action execution failed ", LogType.error, ex.Message)
}
}
}
由此類我使用的接口，用於收集下同名每個不同類型的參數，但是編譯器要完全相同的類型和接口類型似乎沒有幫助。
private void LoadScene(cScene ascn)
{
ascn.LoadScene();
}
public CGTask GetTask(String btnName)
{
CGTask back = new CGTask();
CGTaskHandler1<IControllerBase> alomelo = LoadScene; // type mismatch
back.RegisterCGTask(alomelo, thisScene);
//CGTask2<cScene> back = new CGTask2<cScene>();
//CGTaskHandler1<cScene> alomelo = LoadScene;
//back.RegisterCGTask(alomelo, thisScene);
return back;
}
，所以我改變了我的cgtask類泛型類，因此，參數類型是當類實例化自定。
public class CGTask2<T>
{
private CGTaskHandler1<T> Aksiyon;
private T param;
public void RegisterCGTask(CGTaskHandler1<T> aFunc, T aParam)
{
Aksiyon = aFunc;
param = aParam;
}
public void ExecuteCGTask()
{
try
{
Aksiyon(param);
}
catch (Exception ex)
{
Logger.SetLog("action execution failed ", LogType.error, ex.Message);
}
}
}
然而，當我想將它們收集到一個列表中時，我面對同樣的問題。
List<CGTask2<IControllerBase>> gorevler = new List<CGTask2<IControllerBase>>();
gorevler.Add(new CGTask2<cScene>()); // type mismatch
我需要一種方法來保持對象的功能。每次我使用通用函數委託時，我需要指定類型，並且通用函數的類型不可轉換。有沒有辦法做到這一點，保持對函數的引用並將這些引用作爲對象進行收集？

什麼是'cScene'？ – DavidG
我添加了cScene類定義 –
