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

NameDescription
System_CAPS_pubmethodDbEnumerator(DbDataReader)

Initializes a new instance of the DbEnumerator class with the give n data reader.

System_CAPS_pubmethodDbEnumerator(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.

System_CAPS_pubmethodDbEnumerator(IDataReader)

Initializes a new instance of the DbEnumerator class using the specified DataReader.

System_CAPS_pubmethodDbEnumerator(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.

NameDescription
System_CAPS_pubpropertyCurrent

Gets the current element in the collection.

NameDescription
System_CAPS_pubmethodEquals(Object)

Determines whether the specified object is equal to the current object.(Inherited from Object.)

System_CAPS_protmethodFinalize()

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)

System_CAPS_pubmethodGetHashCode()

Serves as the default hash function. (Inherited from Object.)

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_protmethodMemberwiseClone()

Creates a shallow copy of the current Object.(Inherited from Object.)

System_CAPS_pubmethodMoveNext()

Advances the enumerator to the next element of the collection.

System_CAPS_pubmethodReset()

Sets the enumerator to its initial position, which is before the first element in the collection.

System_CAPS_pubmethodToString()

Returns a string that represents the current object.(Inherited from Object.)

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.
