VB.Net IEnumerator（Of Integer，MyClass）不可能吗？

Question

如何返回IEnumerator

的SortedDictionary(Of Integer, MyClass)

我有这个。

Dim dictionaryTest As New SortedDictionary(Of Integer, MyClass)
Dim enumerator As IEnumerator(Of Integer, MyClass) = dictionaryTest.GetEnumerator() '<- not possible.

我想要一个像

这样的功能

public function getTestEnumerator() as IEnumerator(Of Integer, MyClass)
   return dictionaryTest.GetEnumerator()
end function

IDE中生成错误 'System.Collections.IEnumerator' has no type parameters and so cannot have type arguments.

Answer 1

Dim dictionaryTest As New SortedDictionary(Of Integer, MyClass)

答案是替换

Dim enumerator As IEnumerator(Of Integer, MyClass) = dictionaryTest.GetEnumerator() '<- not possible.

与

Dim enumerator As IEnumerator(Of KeyValuePair(Of Integer, Myclass)) = dictionaryTest.GetEnumerator()
