OracleConnectionStringBuilder.OracleConnectionStringBuilder(String) Constructor

Initializes a new instance of the OracleConnectionStringBuilder class. The provided connection string provides the data for the instance's internal connection information.

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

public OracleConnectionStringBuilder (
	string connectionString
)
public OracleConnectionStringBuilder (
	String connectionString
)
public function OracleConnectionStringBuilder (
	connectionString : String
)
Not applicable.

Parameters

connectionString

The basis for the object's internal connection information. Parsed into name/value pairs. Invalid key names raise a KeyNotFoundException.

Exception typeCondition

KeyNotFoundException

Invalid key name within the connection string.

FormatException

Invalid value within the connection string (specifically, when a Boolean or numeric value was expected but not supplied).

The OracleConnectionStringBuilder class provides a fixed internal collection of key/value pairs. Even if you supply only a small subset of the possible connection string values in the constructor, the object always provides default values for each key/value pair. When the ConnectionString property of the object is retrieved, the string contains only key/value pairs in which the value is different from the default value for the item.

The following example supplies a simple connection string in the OracleConnectionStringBuilder object's constructor, and then iterates through all the key/value pairs within the object. Note that the collection provides default values for each items. Also note that the OracleConnectionStringBuilder class converts synonyms for the well-known keys so that they are consistent with the well-known names.

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.
