GetValueOrDefault<TKey, TValue, TResult>(IReadOnlyDictionary<TKey, TValue>, TKey, TResult)
DictionaryExtensions.csGets a value from the dictionary and converts it to the specified type, or returns a default value if the key is not found or conversion fails.
public static TResult GetValueOrDefault<TKey, TValue, TResult>(this IReadOnlyDictionary<TKey, TValue> dict, TKey key, TResult defaultValue) where TKey : notnullType parameters
TKey- The type of keys in the dictionary.
TValue- The type of values in the dictionary.
TResult- The target type to convert the value to.
Parameters
dictIReadOnlyDictionary<TKey, TValue>- The dictionary to retrieve the value from.
keyTKey- The key of the value to retrieve.
defaultValueTResult- The value to return if the key is not found or conversion fails.
Returns
TResult The converted value if found and conversion succeeded; otherwise, defaultValue.
TryGetValueOrDefault<TKey, TValue, TResult>(IReadOnlyDictionary<TKey, TValue>, TKey, TResult)
DictionaryExtensions.csAttempts to get a value from the dictionary and convert it to the specified type.
public static bool TryGetValueOrDefault<TKey, TValue, TResult>(this IReadOnlyDictionary<TKey, TValue> dict, TKey key, out TResult value) where TKey : notnullType parameters
TKey- The type of keys in the dictionary.
TValue- The type of values in the dictionary.
TResult- The target type to convert the value to.
Parameters
dictIReadOnlyDictionary<TKey, TValue>- The dictionary to retrieve the value from.
keyTKey- The key of the value to retrieve.
