如何在類中調(diào)用類Run()中的函數(shù)？ControllerI2Cclass Program{ public class Controller { public void Run() { } } public class ChildController : Controller { } public class LowLevelController : ChildController { private class I2C { public I2C() { } // Want to call Controller.Run() from this level } public void Computate() { base.Run(); } }}

選項(xiàng)1
實(shí)現(xiàn)此目的的一種方法是在 I2C 中公開(kāi)接受操作的方法。這將允許 I2C 實(shí)例（它是LowLevelController 中定義的私有類）調(diào)用 Controller.Run。例如，
private class I2C
{
public I2C()
{
}
public void RunBase(Action execute)
{
execute.Invoke();
}
}
現(xiàn)在您可以將 RunBase 執(zhí)行為
public void Computate()
{
var i2c = new I2C();
i2c.RunBase(()=>base.Run());
}
選項(xiàng)2
另一種選擇是將 LowLevelController 的實(shí)例傳遞給 I2C 并調(diào)用 Controller.Run 方法
例子，
public class LowLevelController : ChildController
{
private class I2C
{
private LowLevelController _parent;
public I2C(LowLevelController parent)
{
_parent = parent;
}
public void RunBase()
{
_parent.Run();
}
}
public void Computate()
{
var i2c = new I2C(this);
i2c.RunBase();
}
}

我想你想要的很簡(jiǎn)單：
public class LowLevelController : ChildController {
private class I2C {
public I2C(LowLevelController outerInstance) {
OuterInstance = outerInstance;
}
private LowLevelController OuterInstance { get; }
private void DoSomething() {
OuterInstance.Run();
}
}
}
