Collects all parameters relevant to a Command object and their mappings to System.Data.DataSet columns, and is implemented by .NET Framework data providers that access data sources.

public interface IDataParameterCollection : IList


The System.Data.IDataParameterCollection interface allows an inheriting class to implement a Parameter collection. For more information about Parameter classes, see Using Stored Procedures with a Command.

An application does not create an instance of the System.Data.IDataParameterCollection interface directly, but creates an instance of a class that inherits System.Data.IDataParameterCollection.

Classes that inherit System.Data.IDataParameterCollection must implement the inherited members, and typically define additional members to add provider-specific functionality. For example, the System.Data.IDataParameterCollection interface defines one implementation of the IDataParameterCollection.RemoveAt(string) method. In turn, the System.Data.OleDb.OleDbParameterCollection class inherits this method, and defines two additional overloads of RemoveAt.
