此 API 支持产品基础结构,不能在代码中直接使用。

generic <typename TRow>
public ref class EnumerableRowCollection : System::Data::EnumerableRowCollection, System::Collections::Generic::IEnumerable<TRow>
public class EnumerableRowCollection<TRow> : System.Data.EnumerableRowCollection, System.Collections.Generic.IEnumerable<TRow>
type EnumerableRowCollection<'Row> = class
    inherit EnumerableRowCollection
    interface seq<'Row>
    interface IEnumerable
Public Class EnumerableRowCollection(Of TRow)
Inherits EnumerableRowCollection
Implements IEnumerable(Of TRow)

类型参数
