TypeExtensions

Examples

TypeExtensions provides extension methods for Type that simplify classification and metadata retrieval via methods like ToFriendlyName, ToTypeCode, and various Has*/Is* predicates. This example inspects IList<string>, ConcurrentDictionary<string, int>, StringComparer, int?, and anonymous types, calling HasEnumerableImplementation, HasDictionaryImplementation, IsNullable, IsComplex, GetDefaultValue, and ToFriendlyName. It also demonstrates HasAnonymousCharacteristics on an anonymous object, HasTypes for hierarchy checks, HasInterfaces for generic interface matching, and HasAttributes for attribute presence. Console output prints friendly type names like IList<String>, boolean capability flags, and the default value 0 for typeof(int).

Methods

Name	Description
GetDefaultValue(Type)	Gets the default value of the specified type.
HasAnonymousCharacteristics(Type)	Determines whether the specified type suggest an anonymous implementation (be that in a form of a type, delegate or lambda expression).
HasAttributes(Type, params Type[])	Determines whether the specified type contains one or more of the specified attributeTypes.
HasComparableImplementation(Type)	Determines whether the specified type implements either IComparable or IComparable<T>.
HasComparerImplementation(Type)	Determines whether the specified type implements either IComparer or IComparer<T>.
HasDictionaryImplementation(Type)	Determines whether the specified type implements either IDictionary, IDictionary<TKey, TValue> or IReadOnlyDictionary<TKey, TValue>.
HasEnumerableImplementation(Type)	Determines whether the specified type implements either IEnumerable or IEnumerable<T>.
HasEqualityComparerImplementation(Type)	Determines whether the specified type implements either IEqualityComparer or IEqualityComparer<T>.
HasInterfaces(Type, params Type[])	Determines whether the specified type contains one or more of the target interfaces specified throughout this member's inheritance chain.
HasKeyValuePairImplementation(Type)	Determines whether the specified type implements either DictionaryEntry or KeyValuePair<TKey, TValue>.
HasTypes(Type, params Type[])	Determines whether the specified type type contains one or more of the specified target types.
IsComplex(Type)	Determines whether the specified type is a complex Type.
IsNullable(Type)	Determines whether the specified type is a nullable ValueType.
IsSimple(Type)	Determines whether the specified type is a simple Type.
ToFriendlyName(Type, Action<TypeNameOptions>)	Converts the name of the type with the intend to be understood by humans.
ToTypeCode(Type)	Gets the underlying type code of the specified type.
