Because the Remove method returns a value that indicates its success, it is not required to look for a key before trying to remove the key/value pair from the System.Data.SqlClient.SqlConnectionStringBuilder instance. Because the System.Data.SqlClient.SqlConnectionStringBuilder maintains a fixed-size collection of key/value pairs, calling the SqlConnectionStringBuilder.Remove(string) method simply resets the value of the key/value pair back to its default value.

Because the collection of keys supported by the System.Data.SqlClient.SqlConnectionStringBuilder 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 System.Data.SqlClient.SqlConnectionStringBuilder is first initialized, or after the SqlConnectionStringBuilder.Remove(string) method has been called.
