Methods
Name
Description
Cancels the asynchronous call, returning immediately.
Derives, in an asynchronous manner, a set of parameters for use with a specified command.
Derives, in an asynchronous manner, the schema of the specified command.
Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Executes a command in an asynchronous manner.
Executes, in an asynchronous manner, a command that does not return any results beyond an integer value indicating status.
.gif "Protected method")
Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Serves as a hash function for a particular type. (Inherited from Object.)
Gets the type of the current instance. (Inherited from Object.)
Creates a shallow copy of the current Object. (Inherited from Object.)
Dispatches the asynchronous cancel operation to the appropriate synchronous method.
Dispatches the asynchronous derive parameters operation to the synchronous DeriveParameters method call.
Raises the DeriveParametersCompleted event.
Dispatches the asynchronous derive schema operation to the synchronous DeriveSchema method call.
Raises the DeriveSchemaCompleted event.
Dispatches the asynchronous execute operation to the synchronous Execute method call.
Raises the ExecuteCompleted event.
Dispatches the asynchronous execute-without-results operation to the synchronous ExecuteWithoutResults method call.
OnExecuteWithoutResultsCompleted
Raises the ExecuteWithoutResultsCompleted event.
Dispatches the asynchronous prepare operation to the synchronous Prepare method call.
Raises the PrepareCompleted event.
Raises the SiteChanged event. (Inherited from DataSiteableObject<T>.)
Prepares, in an asynchronous manner, the specified command to be executed against the data source; the command may then be executed multiple times, with varying parameters.
Returns a string that represents the current object. (Inherited from Object.)

Properties
Name
Description
.gif "Public property")
Gets or sets the object site. (Inherited from DataSiteableObject<T>.)
