Syntax

public static class UnityContainerExtensions

Methods

BuildUp(IUnityContainer, Type, Object, ResolverOverride[])

Run an existing object through the container and perform injection on it.

Declaration

public static object BuildUp(this IUnityContainer container, Type t, object existing, params ResolverOverride[] resolverOverrides)

Parameters

Type	Name	Description
IUnityContainer	container	Container to resolve through.
Type	t	Type of object to perform injection on.
Object	existing	Instance to build up.
ResolverOverride[]	resolverOverrides	Any overrides for the Buildup.

Returns

Type	Description
Object	The resulting object. By default, this will be existing, but container extensions may add things like automatic proxy creation which would cause this to return a different object (but still type compatible with t).

Remarks

This method is useful when you don't control the construction of an instance (ASP.NET pages or objects created via XAML, for instance) but you still want properties and other injection performed.

This overload uses the default registrations.

BuildUp<T>(IUnityContainer, T, String, ResolverOverride[])

Run an existing object through the container and perform injection on it.

Declaration

public static T BuildUp<T>(this IUnityContainer container, T existing, string name, params ResolverOverride[] resolverOverrides)

Parameters

Type	Name	Description
IUnityContainer	container	Container to resolve through.
T	existing	Instance to build up.
String	name	name to use when looking up the typemappings and other configurations.
ResolverOverride[]	resolverOverrides	Any overrides for the Buildup.

Returns

Type	Description
T	The resulting object. By default, this will be existing, but container extensions may add things like automatic proxy creation which would cause this to return a different object (but still type compatible with T).

Type Parameters

Name	Description
T	Type of object to perform injection on.

Remarks

This method is useful when you don't control the construction of an instance (ASP.NET pages or objects created via XAML, for instance) but you still want properties and other injection performed.

BuildUp<T>(IUnityContainer, T, ResolverOverride[])

Type Parameters

Name	Description
T	Type of object to perform injection on.

Remarks

This method is useful when you don't control the construction of an instance (ASP.NET pages or objects created via XAML, for instance) but you still want properties and other injection performed.

Returns

Type	Description
IUnityContainer	The IUnityContainer object that this method was called on.

Type Parameters

Name	Description
TFrom	Type that will be requested.
TTo	Type that will actually be returned.

Remarks

This method is used to tell the container that when asked for type TFrom, actually return an instance of type TTo. This is very useful for getting instances of interfaces.

RegisterType<TFrom, TTo>(IUnityContainer, String, ITypeLifetimeManager, InjectionMember[])

Register a type mapping with the container, where the created instances will use the given LifetimeManager.

Declaration

public static IUnityContainer RegisterType<TFrom, TTo>(this IUnityContainer container, string name, ITypeLifetimeManager lifetimeManager, params InjectionMember[] injectionMembers)
    where TTo : TFrom

Parameters

Type	Name	Description
IUnityContainer	container	Container to configure.
String	name	Name to use for registration, null if a default registration.
ITypeLifetimeManager	lifetimeManager	The LifetimeManager that controls the lifetime of the returned instance.
InjectionMember[]	injectionMembers	Injection configuration objects.

Returns

Type	Description
IUnityContainer	The IUnityContainer object that this method was called on.

Type Parameters

Name	Description
TFrom	Type that will be requested.
TTo	Type that will actually be returned.

RegisterType<TFrom, TTo>(IUnityContainer, InjectionMember[])

Register a type mapping with the container.

Declaration

public static IUnityContainer RegisterType<TFrom, TTo>(this IUnityContainer container, params InjectionMember[] injectionMembers)
    where TTo : TFrom

Parameters

Type	Name	Description
IUnityContainer	container	Container to configure.
InjectionMember[]	injectionMembers	Injection configuration objects.

Returns

Type	Description
IUnityContainer	The IUnityContainer object that this method was called on.

Type Parameters

Name	Description
TFrom	Type that will be requested.
TTo	Type that will actually be returned.

Remarks

This method is used to tell the container that when asked for type TFrom, actually return an instance of type TTo. This is very useful for getting instances of interfaces.

This overload registers a default mapping and transient lifetime.

RegisterType<TFrom, TTo>(IUnityContainer, ITypeLifetimeManager, InjectionMember[])

    where TTo : TFrom

Parameters

Type	Name	Description
IUnityContainer	container	Container to configure.
ITypeLifetimeManager	lifetimeManager	The LifetimeManager that controls the lifetime of the returned instance.
InjectionMember[]	injectionMembers	Injection configuration objects.

Returns

Type	Description
IUnityContainer	The IUnityContainer object that this method was called on.

Type Parameters

Name	Description
TFrom	Type that will be requested.
TTo	Type that will actually be returned.

Resolve(IUnityContainer, Type, ResolverOverride[])

Resolve an instance of the default requested type from the container.

Declaration

public static object Resolve(this IUnityContainer container, Type t, params ResolverOverride[] overrides)

Parameters

Type	Name	Description
IUnityContainer	container	Container to resolve from.
Type	t	Type of object to get from the container.
ResolverOverride[]	overrides	Any overrides for the resolve call.

Returns

Type	Description
Object	The retrieved object.

Resolve<T>(IUnityContainer, String, ResolverOverride[])

Resolve an instance of the requested type with the given name from the container.

Declaration

public static T Resolve<T>(this IUnityContainer container, string name, params ResolverOverride[] overrides)

Parameters

Type	Name	Description
IUnityContainer	container	Container to resolve from.
String	name	Name of the object to retrieve.
ResolverOverride[]	overrides	Any overrides for the resolve call.

Returns

Type	Description
T	The retrieved object.

Type Parameters

Name	Description
T	Type of object to get from the container.

Resolve<T>(IUnityContainer, ResolverOverride[])

Resolve an instance of the default requested type from the container.

Declaration

public static T Resolve<T>(this IUnityContainer container, params ResolverOverride[] overrides)

Parameters

Type	Name	Description
IUnityContainer	container	Container to resolve from.
ResolverOverride[]	overrides	Any overrides for the resolve call.

Returns

Type	Description
T	The retrieved object.

Type Parameters

Name	Description
T	Type of object to get from the container.

ResolveAll(IUnityContainer, Type, ResolverOverride[])

Return instances of all registered types requested.

Declaration

public static IEnumerable<object> ResolveAll(this IUnityContainer container, Type type, params ResolverOverride[] resolverOverrides)

Parameters

Type	Name	Description
IUnityContainer	container	Container to resolve from.
Type	type	The type requested.
ResolverOverride[]	resolverOverrides	Any overrides for the resolve calls.

Returns

Type	Description
IEnumerable<Object>	Set of objects of type type.

Remarks

This method is useful if you've registered multiple types with the same Type but different names.

Be aware that this method does NOT return an instance for the default (unnamed) registration.

ResolveAll<T>(IUnityContainer, ResolverOverride[])

Return instances of all registered types requested.

Declaration

public static IEnumerable<T> ResolveAll<T>(this IUnityContainer container, params ResolverOverride[] resolverOverrides)

Parameters

ResolverOverride[]	resolverOverrides	Any overrides for the resolve calls.

Returns

Type	Description
IEnumerable<T>	Set of objects of type T.

Type Parameters

Name	Description
T	The type requested.

Remarks

This method is useful if you've registered multiple types with the same Type but different names.

Be aware that this method does NOT return an instance for the default (unnamed) registration.
