Collects all parameters relevant to a Command object and their mappings to DataSet columns, and is implemented by .NET Framework data providers that access data sources.
Assembly: System.Data (in System.Data.dll)
Thetype exposes the following members.
|Count||Gets the number of elements contained in the ICollection. (Inherited from ICollection.)|
|IsFixedSize||Gets a value indicating whether the IList has a fixed size. (Inherited from IList.)|
|IsReadOnly||Gets a value indicating whether the IList is read-only. (Inherited from IList.)|
|IsSynchronized||Gets a value indicating whether access to the ICollection is synchronized (thread safe). (Inherited from ICollection.)|
|Item[Int32]||Gets or sets the element at the specified index. (Inherited from IList.)|
|Item[String]||Gets or sets the parameter at the specified index.|
|SyncRoot||Gets an object that can be used to synchronize access to the ICollection. (Inherited from ICollection.)|
|Add||Adds an item to the IList. (Inherited from IList.)|
|Clear||Removes all items from the IList. (Inherited from IList.)|
|Contains(Object)||Determines whether the IList contains a specific value. (Inherited from IList.)|
|Contains(String)||Gets a value indicating whether a parameter in the collection has the specified name.|
|CopyTo||Copies the elements of the ICollection to an Array, starting at a particular Array index. (Inherited from ICollection.)|
|GetEnumerator||Returns an enumerator that iterates through a collection. (Inherited from IEnumerable.)|
|IndexOf(Object)||Determines the index of a specific item in the IList. (Inherited from IList.)|
|IndexOf(String)||Gets the location of the IDataParameter within the collection.|
|Insert||Inserts an item to the IList at the specified index. (Inherited from IList.)|
|Remove||Removes the first occurrence of a specific object from the IList. (Inherited from IList.)|
|RemoveAt(Int32)||Removes the IList item at the specified index. (Inherited from IList.)|
|RemoveAt(String)||Removes the IDataParameter from the collection.|
|AsParallel||Enables parallelization of a query. (Defined by ParallelEnumerable.)|
|AsQueryable||Converts an IEnumerable to an IQueryable. (Defined by Queryable.)|
|Cast<TResult>||Casts the elements of an IEnumerable to the specified type. (Defined by Enumerable.)|
|OfType<TResult>||Filters the elements of an IEnumerable based on a specified type. (Defined by Enumerable.)|
The interface allows an inheriting class to implement a Parameter collection. For more information about Parameter classes, see Configuring Parameters and Parameter Data Types (ADO.NET).
An application does not create an instance of the interface directly, but creates an instance of a class that inherits .
Classes that inherit must implement the inherited members, and typically define additional members to add provider-specific functionality. For example, the 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 interface, you should implement the following constructor.
Creates an empty PrvParameterCollection class.
