Public Members

name	description
DefaultConnectionStrings(…)	The default connection string source.
virtual GetConnectionKeyFallbacks(…)
virtual GetConnectionKeysResolvingTo(…)	Returns all connection keys (including themselves) whose fallback chain resolves to the specified connection key. Only keys that actually resolve to a configured connection are included, so this is a configuration-aware operation.
virtual ListConnectionStrings()	Lists all known connection strings.
virtual ResolveConnectionKey(…)
virtual TryGetConnectionString(…)	Gets a connection string by its key, resolving any connection key fallbacks. If the specified key is not configured but has a fallback, the fallback connection string is returned. The returned `ConnectionKey` is the key the connection is actually registered under.

name	description
readonly byKey	The cached dictionary of connection string infos.
fallbackMap	The lazily built connection key fallback map.
readonly options	The options.
readonly sqlDialectMapper	The SQL dialect mapper.
virtual ApplyConfigFallbacks(…)	Applies config-driven fallbacks declared via `FallbackFor` to the given map. These override any fallback declared by assembly attributes. If two configured connections declare the same connection key in `FallbackFor`, an InvalidOperationException is thrown because the fallback target is ambiguous.
virtual DetermineDialect(…)	Determines the dialect for a connection.
virtual GetFallbackMap()	Gets the connection key fallback map. The default implementation builds it lazily on first access and caches it in `fallbackMap`. Override to change caching or invalidation behavior, e.g. to return a fresh map each access (no caching).
static BuildFallbackMap(…)	Builds the connection key fallback map from the given type source.

Creates a new instance of DefaultConnectionStrings.
