Namespace: System.Data.OracleClient
Assembly: System.Data.OracleClient (in system.data.oracleclient.dll)

virtual bool Remove (
	String^ keyword
) override

Not applicable.

Parameters

keyword

The key of the key/value pair to be removed from the connection string in this OracleConnectionStringBuilder.

Return Value

true if the key existed within the connection string and was removed, false if the key did not exist.

Exception typeCondition

ArgumentNullException

keyword is null (Nothing in Visual Basic).

Because the Remove method returns a value that indicates its success, it is not necessary to look for the existence of a key before trying to remove the key/value pair from the OracleConnectionStringBuilder instance. Because the OracleConnectionStringBuilder maintains a fixed-size collection of key/value pairs, calling the Remove method just resets the value of the key/value pair back to its default value.

Because the collection of keys supported by the OracleConnectionStringBuilder is fixed, every item within the collection has a known default value.

The following table lists the keys, and the value for each when the OracleConnectionStringBuilder is first initialized, or after the Remove method has been called:

The following example converts an existing connection string from using Windows Authentication to using integrated security. The example works by removing the user name and password from the connection string, and then setting the IntegratedSecurity property of the OracleConnectionStringBuilder object.

NoteNote:

This example includes a password to demonstrate how OracleConnectionStringBuilder works with connection strings. In your applications, we recommend that you use Windows Authentication. If you must use a password, do not include a hard-coded password in your application.
