VC.net继承IEnumerator接口的问题

[北京的雾霾天]

有如下代码：

		ref class Enumerator : System::Collections::Generic::IEnumerator<ItemType>, System::IDisposable
		{
		private:
			ItemCollection<ItemType>^ m_List;
			System::Int32 m_Index;
			System::Int32 m_Version;
			ItemType m_Current;
		public:
			Enumerator(ItemCollection<ItemType>^ list)
			{
				this->m_List=list;
				this->m_Index=0;
				this->m_Version=list->m_Version;
				this->m_Current=ItemType();
			}
			virtual System::Boolean MoveNext()
			{
				ItemCollection<ItemType>^ list = this->m_List;
				if ((this->m_Version == list->m_Version) && (this->m_Index < list->m_Size))
				{
					this->m_Current = list->m_InnerArray[this->m_Index];
					this->m_Index++;
					return true;
				}
				if (this->m_Version != list->m_Version)
				{
					 throw gcnew System::InvalidOperationException("集合已改变，操作无效");
				}
				this->m_Index = this->m_List->m_Size + 1;
				this->m_Current = ItemType();
				return false;
			}
			//1
			property virtual System::Object^ Current
			{
				System::Object^ get(){return this->m_Current;}
			}
			property virtual ItemType Current
			{
				ItemType get()
				{
					return this->m_Current;
				}
			}
			virtual void Reset()
			{
				this->m_Index = 0;
				this->m_Current = ItemType();
			}
			~Enumerator()
			{
			}

在标记1处的Current是不符合接口定义的，需要定义泛型的Current属性。

			property virtual ItemType Current
			{
				ItemType get(){return this->m_Current;}
			}

但是两个Current不能同时定义，怎么办？
VC.Net的显式重写并不能解决属性的问题，那该如何实现这个自定义的Class？

没怎么看明白- - ，帮顶了。

主要是同名属性的问题，属性名称相同，但是类型不一样。 在C#里通过显示实现接口就行了，但是在VC.Net语法都通不过。

[真相重于对错]

你这个不符合c++/clr语法

[真相重于对错]

给你找个msdn的代码

// for_each_generics.cpp
// compile with: /clr
using namespace System;
using namespace System::Collections::Generic;

generic <class T>
public value struct MyArray : public IEnumerable<T> {   

   MyArray( array<T>^ d ) {
      data = d;
   }

   ref struct enumerator : IEnumerator<T> {
      enumerator( MyArray^ myArr ) {
         colInst = myArr;
         currentIndex = -1;
      }

      virtual bool MoveNext() = IEnumerator<T>::MoveNext {
         if ( currentIndex < colInst->data->Length - 1 ) {
            currentIndex++;
            return true;
         }

         return false;
      }

      virtual property T Current {
         T get() {
            return colInst->data[currentIndex];
         }
      };

      property Object^ CurrentNonGeneric {
         virtual Object^ get() = System::Collections::IEnumerator::Current::get {
            return colInst->data[currentIndex];
         }
      };

      virtual void Reset() {}
      ~enumerator() {}

      MyArray^ colInst;
      int currentIndex;
   };

   array<T>^ data;

   virtual IEnumerator<T>^ GetEnumerator() {
      return gcnew enumerator(*this);
   }
   virtual System::Collections::IEnumerator^ GetEnumeratorNonGeneric() = System::Collections::IEnumerable::GetEnumerator {
      return gcnew enumerator(*this);
   }
};

int main() {
   MyArray<int> col = MyArray<int>( gcnew array<int>{10, 20, 30 } );

   for each ( Object^ c in col )
      Console::WriteLine((int)c);
}

OK! 就是我想要的！ 我没有找到这个示例，所以非常感谢！
