AdoDotNetConnectionSupport Members

Provides a managed implementation of the DataConnectionSupport, DataCommand, and DataTransaction classes using the ADO.NETIDbConnection, IDbCommand, and IDbTransactioninterfaces, respectively; also provides a simple way to supply an implementation of the DataSourceVersionComparerclass.

The AdoDotNetConnectionSupport type exposes the following members.

Constructors

Methods

	Name	Description
	BeginTransaction	Initiates a transaction and returns the new current transaction level.
	Close	Closes the specified data connection. (Overrides DataConnectionSupport.Close().)
	CommitTransaction	Commits a transaction and returns the new current transaction level.
	CompareVersions	Compares two data-source version strings and returns a value indicating whether one is less than, equal to, or greater than the other.
	CreateDataSourceInformation	Creates a DataSourceInformation object instance.
	CreateObjectIdentifierConverter	Creates a DataObjectIdentifierConverter object instance.
	CreateObjectItemComparer	Creates a object instance.
	CreateParameter	Creates a DataParameter object.
	DeriveParameters	Derives parameters that can be specified for a given command
	DeriveSchema	Derives the schema returned from a specified command, indicating the layout of items and blocks in a given data reader.
	Dispose	Overloaded. Releases all resources held by the data connection.
	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Execute	Executes a specified command, optionally with parameters, and returns results as a DataReader object.
	ExecuteWithoutResults	Executes a command, optionally with parameters, but does not request results, instead returning an integer indicating the outcome of the call.
	Finalize	(Inherited from DataConnectionSupport.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetService	Overloaded.
	GetServiceImpl	Overloaded. Enables retrieving implementation services.
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	Initialize	Initializes the specified ADO.NET connection using a specified provider. (Overrides DataConnectionSupport.Initialize(Object).)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	OnSiteChanged	Raises the SiteChanged event. (Inherited from ServiceProviderWithSite.)
	Open	Opens the specified data connection. (Overrides DataConnectionSupport.Open(Boolean).)
	Prepare	Prepares the specified command on the data source to be executed; the command may be executed multiple times, with varying parameters.
	RaiseMessageReceived	Raises the MessageReceivedevent on the enclosing DataConnection instance. (Inherited from DataConnectionSupport.)
	RaiseStateChanged	Raises the state changed event on the enclosing DataConnection instance. (Inherited from DataConnectionSupport.)
	RollbackTransaction	Rolls back, or voids, a transaction and returns the new current transaction level.
	ToString	Returns a String that represents the current Object. (Inherited from Object.)

Properties

	Name	Description
	BaseCommand	Retrieves the main IDbCommand object being used for executing commands on this connection.
	Connection	Retrieves the IDbConnection object being used by the current connection support instance.
	ConnectionString	Retrieves or sets a string representation of information required to establish a specified data source connection. (Overrides DataConnectionSupport.ConnectionString.)
	ConnectionTimeout	Retrieves or sets the amount of time, in seconds, to wait to establish a connection before terminating the attempt and generating a timeout error. (Overrides DataConnectionSupport.ConnectionTimeout.)
	CurrentTransactionLevel	Retrieves the current transaction level.
	ExecutingCommand	Retrieves the IDbCommand instance currently being used for execution.
	PreparedCommands	Retrieves a list of IDbCommand objects that have been previously prepared.
	ProviderObject	Retrieves the underlying provider object for the specified connection. (Overrides DataConnectionSupport.ProviderObject.)
	ServiceTypes	Retrieves a list of service types used to convert the unmanaged QueryService method call, in which a service GUID is specified, into a managed IServiceProvider.GetService method call, in which a managed type is specified. (Inherited from ServiceProvider.)
	Site	Retrieves or sets the site object instance. (Inherited from ServiceProviderWithSite.)
	State	Retrieves the state of the data connection. (Overrides DataConnectionSupport.State.)
	Transaction	Retrieves the current IDbTransaction, if any.
