Assembly: System.Data (in system.data.dll)
The IDataParameterCollection interface allows an inheriting class to implement a Parameter collection. For more information about Parameter classes, see Using Stored Procedures with a Command. For more information about implementing .NET Framework data providers, see Implementing a .NET Framework Data Provider.
An application does not create an instance of the IDataParameterCollection interface directly, but creates an instance of a class that inherits IDataParameterCollection.
Classes that inherit IDataParameterCollection must implement the inherited members, and typically define additional members to add provider-specific functionality. For example, the IDataParameterCollection interface defines one implementation of the RemoveAt method. In turn, the OleDbParameterCollection class inherits this method, and defines two additional overloads of RemoveAt.Notes to Implementers When you inherit from the IDataParameterCollection interface, you should implement the following constructor:
Creates an empty PrvParameterCollection class.
The following example creates multiple instances of the derived class, SqlParameter, through the SqlParameterCollection collection within the SqlDataAdapter. These parameters are used to select data from the data source and place the data in the DataSet. This example assumes that a DataSet and a SqlDataAdapter have already been created with the appropriate schema, commands, and connection.
