我想存储一些通用函数以便以后执行。问题出现在函数的论证上。对于不同的类型，我想创建和存储相同的泛型函数委托，但我不能这样做。下面是我获取函数的类版本;
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)
}
}
}
通过这个类我使用一个接口来收集同名的每个不同类型的参数，但是编译器想要完全相同的类型和接口类型似乎无济于事。
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;
}
因此我将我的cgtask类更改为泛型类，因此，当实例化类时，参数类型将是明确的。
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，当我想在列表中收集它们时，我遇到同样的问题。
List<CGTask2<IControllerBase>> gorevler = new List<CGTask2<IControllerBase>>();
gorevler.Add(new CGTask2<cScene>()); // type mismatch
我需要一种保持对象等功能的方法。每次我使用泛型函数委托时，我都需要指定类型，并且泛型函数的类型不可转换。有没有办法做到这一点，保持对函数的引用并将这些引用收集为对象？
public interface IControllerBase
{
void GetTalker();
void InitiliazeTalker();
}
public class cControllerBase : IControllerBase
{
public cControllerBase Parent=null;

{
tk = Talker.Instance; // not initialized yet

{
tk.InitializeReTalk();
}

}
tempexport.Parent = this;

return true;
}
public void ActivateScene()

public void LoadScene()

public void SetSceneName(String strxmlPath)
{

SceneName = strxmlPath.Substring(0, strxmlPath.LastIndexOf('\\'));

}
}
答案 0 :(得分：0)
CGTask2<cScene>与CGTask2<IControllerBase>的类型完全不同，您不能将两者等同起来。您必须有一个列表，例如ITask和make CGTask2实现它。例如：
public interface ITask {}
public class CGTask2<T> : ITask
{
//snip
}
现在你可以这样做：
List<ITask> gorevler = new List<ITask>();
gorevler.Add(new CGTask2<cScene>());
