EnumerableRowCollection EnumerableRowCollection EnumerableRowCollection EnumerableRowCollection Class


表示从 LINQ to DataSet 查询返回的 DataRow 对象的集合。Represents a collection of DataRow objects returned from a LINQ to DataSet query. 此 API 支持 .NET Framework 基础结构,但不应在代码中直接使用。This API supports the .NET Framework infrastructure and is not intended to be used directly from your code.

public ref class EnumerableRowCollection abstract : System::Collections::IEnumerable
public abstract class EnumerableRowCollection : System.Collections.IEnumerable

    interface IEnumerable
Public MustInherit Class EnumerableRowCollection
Implements IEnumerable


@no__t 提供了一个入口点,以便可以在扩展方法中截获强制转换运算。EnumerableRowCollection provides an entry point so that the cast operation can be intercepted within an extension method. .NET Framework 实际使用派生泛型类 EnumerableRowCollection<TRow> 来包含查询的结果。The derived generic class EnumerableRowCollection<TRow> is actually used by the .NET Framework to contain the results of a query.

此类无法实例化。This class cannot be instantiated.
