	Equals	Determines whether two object instances are equal. (Inherited from DtsObject.)
	Execute	Runs the Data Profiling task. (Overrides Task.Execute(Connections, VariableDispenser, IDTSComponentEvents, IDTSLogging, Object).)
	Finalize	(Inherited from Object.)
	GetConnectionID	Gets a String containing the ID of the connection. (Inherited from Task.)
	GetConnectionName	Gets a String containing the name of the connection. (Inherited from Task.)
	GetHashCode	Returns the hash code for this instance. (Inherited from DtsObject.)
	GetType	(Inherited from Object.)
	InitializeTask	Initializes the Data Profiling task. (Overrides Task.InitializeTask(Connections, VariableDispenser, IDTSInfoEvents, IDTSLogging, EventInfos, LogEntryInfos, ObjectReferenceTracker).)
	LoadFromXML	Loads the definition of the task, in XML format, from the XML definition of the package.

	SaveToXML	Saves the definition of the task, in XML format, into the XML definition of the package.
	ToString	(Inherited from Object.)
	Update	* Member deprecated; see Remarks. * This method updates the old package XML with the new package XML if CanUpdate is set to true. (Inherited from Task.)
	Validate	Determines whether the Data Profiling task is correctly configured. (Overrides Task.Validate(Connections, VariableDispenser, IDTSComponentEvents, IDTSLogging).)

Remarks

The DataProfilingTask class is the main class in the Microsoft.SqlServer.Dts.Tasks.DataProfilingTask namespace. This class represents the Integration Services Data Profiling task, which can be used to profile and discover the structure of an unfamiliar data source, and to identify problems with the data.
