DbConnection Methods

The DbConnection type exposes the following members.

  Name Description
Protected method BeginDbTransaction Starts a database transaction.
Public method BeginTransaction() Starts a database transaction.
Public method BeginTransaction(IsolationLevel) Starts a database transaction with the specified isolation level.
Public method ChangeDatabase Changes the current database for an open connection.
Public method Close Closes the connection to the database. This is the preferred method of closing any open connection.
Public method CreateCommand Creates and returns a DbCommand object associated with the current connection.
Protected method CreateDbCommand Creates and returns a DbCommand object associated with the current connection.
Public method CreateObjRef Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. (Inherited from MarshalByRefObject.)
Public method Dispose() Releases all resources used by the Component. (Inherited from Component.)
Protected method Dispose(Boolean) Releases the unmanaged resources used by the Component and optionally releases the managed resources. (Inherited from Component.)
Public method EnlistTransaction Enlists in the specified transaction.
Public method Equals(Object) Determines whether the specified object is equal to the current object. (Inherited from Object.)
Protected method Finalize Releases unmanaged resources and performs other cleanup operations before the Component is reclaimed by garbage collection. (Inherited from Component.)
Public method GetHashCode Serves as the default hash function. (Inherited from Object.)
Public method GetLifetimeService Retrieves the current lifetime service object that controls the lifetime policy for this instance. (Inherited from MarshalByRefObject.)
Public method GetSchema() Returns schema information for the data source of this DbConnection.
Public method GetSchema(String) Returns schema information for the data source of this DbConnection using the specified string for the schema name.
Public method GetSchema(String, String[]) Returns schema information for the data source of this DbConnection using the specified string for the schema name and the specified string array for the restriction values.
Protected method GetService Returns an object that represents a service provided by the Component or by its Container. (Inherited from Component.)
Public method GetType Gets the Type of the current instance. (Inherited from Object.)
Public method InitializeLifetimeService Obtains a lifetime service object to control the lifetime policy for this instance. (Inherited from MarshalByRefObject.)
Protected method MemberwiseClone() Creates a shallow copy of the current Object. (Inherited from Object.)
Protected method MemberwiseClone(Boolean) Creates a shallow copy of the current MarshalByRefObject object. (Inherited from MarshalByRefObject.)
Protected method OnStateChange Raises the StateChange event.
Public method Open Opens a database connection with the settings specified by the ConnectionString.
Public method OpenAsync() An asynchronous version of Open, which opens a database connection with the settings specified by the ConnectionString. This method invokes the virtual method OpenAsync with CancellationToken.None.
Public method OpenAsync(CancellationToken) This is the asynchronous version of Open. Providers should override with an appropriate implementation. The cancellation token can optionally be honored.The default implementation invokes the synchronous Open call and returns a completed task. The default implementation will return a cancelled task if passed an already cancelled cancellationToken. Exceptions thrown by Open will be communicated via the returned Task Exception property.Do not invoke other methods and properties of the DbConnection object until the returned Task is complete.
Public method ToString Returns a String containing the name of the Component, if any. This method should not be overridden. (Inherited from Component.)

In XNA Framework 3.0, this member is inherited from Object.ToString().
