FbConnectionStringBuilder default values behavior
-------------------------------------------------
Key: DNET-281
URL: http://tracker.firebirdsql.org/browse/DNET-281
Project: .NET Data provider
Issue Type: Bug
Components: ADO.NET Provider
Affects Versions: 2.5.1
Environment: Windows
Reporter: Vasily Kabanov
Assignee: Jiri Cincura
Priority: Minor
1) None of the properties in the connection string builder appears to have
default values: if you create new instance with parameterless constructor and
try to get any property value you get an ArgumentException because all the
properties directly query the base class for hard-coded key value. This is very
different from other builders (such as SqlConnectionStringBuilder) and causes
problems such as when you try to create database connection dialog for the
user. All these defaults need to be implemented manually anyway in a wrapper.
fb.FbConnectionStringBuilder fbld = new fb.FbConnectionStringBuilder();
string userID = fbld.UserID; // throws exception
System.Data.SqlClient.SqlConnectionStringBuilder bld = new
System.Data.SqlClient.SqlConnectionStringBuilder();
userID = bld.UserID; // returns empty string
2) If you set a property and then want to revert to default (delete key-value
pair) there's no graceful way (for example, for integer properties) as key
names are hard-coded as literals and not exposed (as public constants, for
example). Also, after creating empty conn.string builder its Keys collection is
empty which is again different from other implementations.
