声明
<SuppressMessageAttribute("Microsoft.Design", "CA1033:InterfaceMethodsShouldBeCallableByChildTypes")> _
Private Function GetAsyncEnumerator As IDbAsyncEnumerator(Of T)
Implements IDbAsyncEnumerable(Of T).GetAsyncEnumerator
用法
Dim instance As ObjectQuery
Dim returnValue As IDbAsyncEnumerator(Of T)
returnValue = CType(instance, IDbAsyncEnumerable(Of T)).GetAsyncEnumerator()
[SuppressMessageAttribute("Microsoft.Design", "CA1033:InterfaceMethodsShouldBeCallableByChildTypes")]

JScript supports the use of explicit interface implementations, but not the declarations of new ones.
