Namespace:
System.Data.OracleClient
Assembly:
System.Data.OracleClient.dll

Initializes a new instance of the OracleConnectionStringBuilder class.

Overloads

OracleConnectionStringBuilder()

OracleConnectionStringBuilder(String)

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

Applies to

OracleConnectionStringBuilder(String)

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

public:
 OracleConnectionStringBuilder(System::String ^ connectionString);
public OracleConnectionStringBuilder (string connectionString);
new System.Data.OracleClient.OracleConnectionStringBuilder : string -> System.Data.OracleClient.OracleConnectionStringBuilder
Public Sub New (connectionString As String)

Parameters

connectionString
String

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

Exceptions

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).

Examples

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.

Note

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.

Module Module1
  Sub Main()
    Try
      Dim connectString As String = "Server=OracleDemo;UID=Mary;Pwd=*****"
      Console.WriteLine("Original: " & connectString)
      Dim builder As New OracleConnectionStringBuilder(connectString)
      Console.WriteLine("Modified: " & builder.ConnectionString)
      For Each key As String In builder.Keys
        Console.WriteLine(key & "=" & builder.Item(key).ToString)
      Next
      Console.WriteLine("Press any key to finish.")
      Console.ReadLine()

    Catch ex As System.Collections.Generic.KeyNotFoundException
      Console.WriteLine("KeyNotFoundException: " & ex.Message)
    Catch ex As System.FormatException
      Console.WriteLine("Format exception: " & ex.Message)
    End Try
  End Sub

End Module

Remarks

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.
