Releases all resources used by the Component.(Inherited from Component.)

System_CAPS_protmethodDispose(Boolean)

Releases the unmanaged resources used by the DataAdapter and optionally releases the managed resources.(Overrides Component.Dispose(Boolean).)

System_CAPS_pubmethodEquals(Object)

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

System_CAPS_pubmethodFill(DataSet)

Adds or refreshes rows in the DataSet to match those in the data source.

System_CAPS_protmethodFill(DataSet, String, IDataReader, Int32, Int32)

Adds or refreshes rows in a specified range in the DataSet to match those in the data source using the DataSet and DataTable names.

System_CAPS_protmethodFill(DataTable, IDataReader)

Adds or refreshes rows in the DataTable to match those in the data source using the DataTable name and the specified IDataReader.

System_CAPS_protmethodFill(DataTable[], IDataReader, Int32, Int32)

Adds or refreshes rows in a specified range in the collection of DataTable objects to match those in the data source.

System_CAPS_pubmethodFillSchema(DataSet, SchemaType)

Adds a DataTable to the specified DataSet and configures the schema to match that in the data source based on the specified SchemaType.

System_CAPS_pubmethodGetType()

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

System_CAPS_protmethodHasTableMappings()

Indicates whether a DataTableMappingCollection has been created.

System_CAPS_pubmethodInitializeLifetimeService()

System_CAPS_protmethodMemberwiseClone()

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

System_CAPS_protmethodMemberwiseClone(Boolean)

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

System_CAPS_protmethodOnFillError(FillErrorEventArgs)

Invoked when an error occurs during a Fill.

System_CAPS_pubmethodResetFillLoadOption()

Resets FillLoadOption to its default state and causes DataAdapter.Fill to honor AcceptChangesDuringFill.

System_CAPS_pubmethodShouldSerializeAcceptChangesDuringFill()

Determines whether the AcceptChangesDuringFill property should be persisted.

System_CAPS_pubmethodShouldSerializeFillLoadOption()

Determines whether the FillLoadOption property should be persisted.

System_CAPS_protmethodShouldSerializeTableMappings()

Determines whether one or more DataTableMapping objects exist and they should be persisted.

System_CAPS_pubmethodToString()

Returns a String containing the name of the Component, if any. This method should not be overridden.(Inherited from Component.)

System_CAPS_pubmethodUpdate(DataSet)

Calls the respective INSERT, UPDATE, or DELETE statements for each inserted, updated, or deleted row in the specified DataSet from a DataTable named "Table."

NameDescription
System_CAPS_pubeventDisposed

Occurs when the component is disposed by a call to the Dispose method. (Inherited from Component.)

System_CAPS_pubeventFillError

Returned when an error occurs during a fill operation.

NameDescription
System_CAPS_pubinterfaceSystem_CAPS_privpropertyIDataAdapter.TableMappings

Indicates how a source table is mapped to a dataset table.

The DataAdapter serves as a bridge between a DataSet and a data source for retrieving and saving data. The DataAdapter provides this bridge by mapping Fill, which changes the data in the DataSet to match the data in the data source, and Update, which changes the data in the data source to match the data in the DataSet.

If you are connecting to a SQL Server database, you can increase overall performance by using the SqlDataAdapter along with its associated SqlCommand and SqlConnection objects. For OLE DB-supported data sources, use the DataAdapter with its associated OleDbCommand and OleDbConnection objects. For ODBC-supported data sources, use the DataAdapter with its associated OdbcCommand and OdbcConnection objects. For Oracle databases, use the DataAdapter with its associated OracleCommand and OracleConnection objects.

When an instance of DataAdapter is created, the read/write properties are set to initial values. For a list of these values, see the DataAdapter constructor.
