Represents a collection of OleDbParameter objects that are used with a single stored procedure or parameterized query and are added to the collection accessed using OleDbCommand.Parameters . You can retrieve an individual OleDbCommand object by its index or by its parameter name . This class also provides an overloaded Add( ) method that lets you create and add an OleDbParameter object to the collection in one step. public sealed class OleDbParameterCollection : MarshalByRefObject , System.Data.IDataParameterCollection, IList, ICollection, IEnumerable { // Public Instance Properties public int Count {get; } // implements ICollection public OleDbParameter this [string parameterName ]{set; get; } public OleDbParameter this [int index ]{set; get; } // Public Instance Methods public int Add ( object value ); // implements IList public OleDbParameter Add ( OleDbParameter value ); public OleDbParameter Add (string parameterName , object value ); public OleDbParameter Add (string parameterName , OleDbType oleDbType ); public OleDbParameter Add (string parameterName , OleDbType oleDbType , int size ); public OleDbParameter Add (string parameterName , OleDbType oleDbType , int size , string sourceColumn ); public void Clear ( ); // implements IList public bool Contains ( object value ); // implements IList public bool Contains ( string value ); // implements System.Data.IDataParameterCollection public void CopyTo ( Array array , int index ); // implements ICollection public IEnumerator GetEnumerator ( ); // implements IEnumerable public int IndexOf ( object value ); // implements IList public int IndexOf ( string parameterName ); // implements System.Data.IDataParameterCollection public void Insert ( int index , object value ); // implements IList public void Remove ( object value ); // implements IList public void RemoveAt ( int index ); // implements IList public void RemoveAt ( string parameterName ); // implements System.Data.IDataParameterCollection } HierarchySystem.Object System.MarshalByRefObject OleDbParameterCollection(System.Data.IDataParameterCollection, System.Collections.IList , System.Collections.ICollection , System.Collections.IEnumerable) Returned ByOleDbCommand.Parameters |
