Namespace: Umbraco.Extensions Assembly: Umbraco.Core.dll Syntaxpublic static class DictionaryExtensionscontains key ignore case.
Declarationpublic static bool ContainsKeyIgnoreCase<TValue>(this IDictionary<string, TValue> dictionary, string key)The dictionary.
System.String keyThe key.
Returns Type Description System.BooleanThe contains key ignore case.
Type Parameters Name Description TValueValue Type
View Source ConvertTo<TKeyOut, TValOut>(IDictionary)Converts a dictionary to another type by only using direct casting
Declarationpublic static IDictionary<TKeyOut, TValOut> ConvertTo<TKeyOut, TValOut>(this IDictionary d)Converts a dictionary to another type using the specified converters
Declarationpublic static IDictionary<TKeyOut, TValOut> ConvertTo<TKeyOut, TValOut>(this IDictionary d, Func<object, TKeyOut> keyConverter, Func<object, TValOut> valConverter)Method to Get a value by the key. If the key doesn't exist it will create a new TVal object for the key and return it.
Declarationpublic static TVal GetOrCreate<TKey, TVal>(this IDictionary<TKey, TVal> dict, TKey key)
where TVal : class, new()Returns the value of the key value based on the key, if the key is not found, a null value is returned
Declarationpublic static TVal GetValue<TKey, TVal>(this IDictionary<TKey, TVal> d, TKey key, TVal defaultValue = null)The d.
TKey keyThe key.
TVal defaultValueThe default value.
Returns Type Parameters Name Description TKeyThe type of the key.
TValThe type of the val.
View Source GetValueAsString<TKey, TVal>(IDictionary<TKey, TVal>, TKey)Returns the value of the key value based on the key as it's string value, if the key is not found, then an empty string is returned
Declarationpublic static string GetValueAsString<TKey, TVal>(this IDictionary<TKey, TVal> d, TKey key)Returns the value of the key value based on the key as it's string value, if the key is not found or is an empty string, then the provided default value is returned
Declarationpublic static string GetValueAsString<TKey, TVal>(this IDictionary<TKey, TVal> d, TKey key, string defaultValue)The get entry ignore case.
Declarationpublic static TValue GetValueIgnoreCase<TValue>(this IDictionary<string, TValue> dictionary, string key)The dictionary.
System.String keyThe key.
Returns Type Description TValueThe entry
Type Parameters Name Description TValueThe type
View Source GetValueIgnoreCase<TValue>(IDictionary<String, TValue>, String, TValue)The get entry ignore case.
Declarationpublic static TValue GetValueIgnoreCase<TValue>(this IDictionary<string, TValue> dictionary, string key, TValue defaultValue)The dictionary.
System.String keyThe key.
TValue defaultValueThe default value.
Returns Type Description TValueThe entry
Type Parameters Name Description TValueThe type
View Source MergeLeft<T, TK, TV>(T, IDictionary<TK, TV>, Boolean)Merges all key/values from the sources dictionaries into the destination dictionary
Declarationpublic static void MergeLeft<T, TK, TV>(this T destination, IDictionary<TK, TV> source, bool overwrite = false)
where T : IDictionary<TK, TV>The source dictionary to merge other dictionaries into
System.Collections.IDictionary<TK, TV> sourceThe other dictionary to merge values from
System.Boolean overwriteBy default all values will be retained in the destination if the same keys exist in the sources but this can changed if overwrite = true, then any key/value found in any of the sources will overwritten in the destination. Note that it will just use the last found key/value if this is true.
Type Parameters View Source MergeLeft<T, TK, TV>(T, IEnumerable<IDictionary<TK, TV>>, Boolean)Merges all key/values from the sources dictionaries into the destination dictionary
Declarationpublic static void MergeLeft<T, TK, TV>(this T destination, IEnumerable<IDictionary<TK, TV>> sources, bool overwrite = false)
where T : IDictionary<TK, TV>The source dictionary to merge other dictionaries into
System.Collections.IEnumerable<System.Collections.IDictionary<TK, TV>> sourcesThe other dictionaries to merge values from
System.Boolean overwriteBy default all values will be retained in the destination if the same keys exist in the sources but this can changed if overwrite = true, then any key/value found in any of the sources will overwritten in the destination. Note that it will just use the last found key/value if this is true.
Type Parameters View Source ToDictionaryAsync<TInput, TKey, TValue>(IEnumerable<TInput>, Func<TInput, TKey>, Func<TInput, Task<TValue>>) Declarationpublic static async Task<Dictionary<TKey, TValue>> ToDictionaryAsync<TInput, TKey, TValue>(this IEnumerable<TInput> enumerable, Func<TInput, TKey> syncKeySelector, Func<TInput, Task<TValue>> asyncValueSelector)Converts a dictionary to a NameValueCollection
Declarationpublic static NameValueCollection ToNameValueCollection(this IDictionary<string, string> d)Converts a dictionary object to a query string representation such as: firstname=shannon&lastname=deminick.
Declarationpublic static string ToQueryString(this IDictionary<string, object> d)Updates an item with the specified key with the specified value
Declarationpublic static bool TryUpdate<TKey, TValue>(this ConcurrentDictionary<TKey, TValue> dict, TKey key, Func<TValue, TValue> updateFactory)Updates an item with the specified key with the specified value
Declarationpublic static bool TryUpdateOptimisitic<TKey, TValue>(this ConcurrentDictionary<TKey, TValue> dict, TKey key, Func<TValue, TValue> updateFactory)RetroSearch is an open source project built by @garambo | Open a GitHub Issue
