DbEnumerator Class

Definition

Namespace:

System.Data.Common

Assembly:

System.Data.Common.dll

Source:

DbEnumerator.cs

Exposes the GetEnumerator() method, which supports a simple iteration over a collection by a .NET data provider.

public ref class DbEnumerator : System::Collections::IEnumerator

public class DbEnumerator : System.Collections.IEnumerator

type DbEnumerator = class
    interface IEnumerator

Public Class DbEnumerator
Implements IEnumerator

Remarks

The DbEnumerator class is implemented by a .NET Framework data provider to provide data binding support.

By design, the DbEnumerator object is intended for use with only one resultset. For example, if you execute a batch statement containing two SQL SELECT statements that return different schemas, the second statement might not retun the entire schema. To avoid this situation, obtain a DbEnumerator for each resultset, and then call the NextResult method of a .NET Framework data provider DataReader object.

Constructors

DbEnumerator(DbDataReader, Boolean)	Initializes a new instance of the DbEnumerator class using the specified reader and indicates whether to automatically close the reader after iterating through its data.
DbEnumerator(DbDataReader)	Initializes a new instance of the DbEnumerator class with the give n data reader.
DbEnumerator(IDataReader, Boolean)	Initializes a new instance of the DbEnumerator class using the specified DataReader, and indicates whether to automatically close the DataReader after iterating through its data.
DbEnumerator(IDataReader)	Initializes a new instance of the DbEnumerator class using the specified DataReader.

Properties

Current

Gets the current element in the collection.

Methods

Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
GetHashCode()	Serves as the default hash function. (Inherited from Object)
GetType()	Gets the Type of the current instance. (Inherited from Object)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
MoveNext()	Advances the enumerator to the next element of the collection.
Reset()	Sets the enumerator to its initial position, which is before the first element in the collection.
