OleDbDataReader.GetEnumerator 方法

定义

返回一个可用于循环访问数据读取器中的行的 IEnumeratorReturns an IEnumerator that can be used to iterate through the rows in the data reader.

public:
 override System::Collections::IEnumerator ^ GetEnumerator();
public override System.Collections.IEnumerator GetEnumerator ();
override this.GetEnumerator : unit -> System.Collections.IEnumerator
Public Overrides Function GetEnumerator () As IEnumerator

返回

一个 IEnumerator,可用于循环访问数据读取器中的行。An IEnumerator that can be used to iterate through the rows in the data reader.

注解

尽管可以使用此方法来检索显式枚举器,但在支持 foreach 构造的语言中,直接使用循环构造来循环访问数据读取器中的行更为简单。Although you can use this method to retrieve an explicit enumerator, in languages that support a foreach construct, it is simpler to use the looping construct directly in order to iterate through the rows in the data reader.
