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

JScript supports the use of explicit interface implementations, but not the declarations of new ones.
返回值
类型：System.Data.Entity.Infrastructure.IDbAsyncEnumerator<TElement>
一个 IDbAsyncEnumerator<T> 对象，可用于循环访问元素。
