OracleConnectionStringBuilder Constructor (String)

OracleConnectionStringBuilder Constructor (String^)


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)

	String^ connectionString


Type: System::String^

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

Exception Condition

Invalid key name within the connection string.


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.


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.
