Activator reflection

Creates an instance of the type whose name is specified, using the named assembly and the constructor that best matches the specified parameters. Creates an instance of the type whose name is specified, using the named assembly and parameterless constructor. Creates an instance of the type that is designated by the specified ActivationContext object and activated with the specified custom activation data. Creates an instance of the type designated by the specified ActivationContext object.

Creates an instance of the type whose name is specified in the specified remote domain, using the named assembly and parameterless constructor. Creates an instance of the type designated by the specified generic type parameter, using the parameterless constructor. Methods which use evidence to sandbox are obsolete and will be removed in a future release of the. NET Framework.

Please use an overload of CreateInstance which does not take an Evidence parameter. The domain where the type named typeName is created. The name of the assembly where the type named typeName is sought. If assemblyName is null , the executing assembly is searched. A combination of zero or more bit flags that affect the search for the typeName constructor.

If bindingAttr is zero, a case-sensitive search for public constructors is conducted. An object that uses bindingAttr and args to seek and identify the typeName constructor. If binder is null , the default binder is used. An array of arguments that match in number, order, and type the parameters of the constructor to invoke.

If args is an empty array or null , the constructor that takes no parameters the parameterless constructor is invoked. Culture-specific information that governs the coercion of args to the formal types declared for the typeName constructor. If culture is null , the CultureInfo for the current thread is used. An array of one or more attributes that can participate in activation. This is typically an array that contains a single UrlAttribute object. Cannot create an instance of an abstract class, or this member was invoked with a late-binding mechanism.

The constructor that best matches args has varargs arguments. The common language runtime CLR version 2. Note that the. NET Framework versions 2. Use CreateInstance when a host needs to execute code in an application domain that has restricted security permissions. Use ObjectHandle. Unwrap to unwrap the return value. This method uses SecurityAction. LinkDemand to require the immediate caller to have full trust. This is typically an array that contains a single UrlAttribute object that specifies the URL that is required to activate a remote object.

This parameter is related to client-activated objects. Client activation is a legacy technology that is retained for backward compatibility but is not recommended for new development. Distributed applications should instead use Windows Communication Foundation. Starting with the.

Creates an instance of the type designated by the specified ActivationContext object. Creates an instance of the type that is designated by the specified ActivationContext object and activated with the specified custom activation data.

Creates an instance of the type whose name is specified in the specified remote domain, using the named assembly and parameterless constructor. Creates an instance of the type whose name is specified in the specified remote domain, using the named assembly and the constructor that best matches the specified parameters. Creates an instance of the type whose name is specified, using the named assembly and parameterless constructor.

Creates an instance of the type whose name is specified, using the named assembly and the constructor that best matches the specified parameters. Creates an instance of the specified type using the constructor that best matches the specified parameters. Creates an instance of the type designated by the specified generic type parameter, using the parameterless constructor. Creates an instance of the type whose name is specified in the specified remote domain, using the named assembly file and parameterless constructor.

Creates an instance of the type whose name is specified in the specified remote domain, using the named assembly file and the constructor that best matches the specified parameters. Creates an instance of the type whose name is specified, using the named assembly file and parameterless constructor. Creates an instance of the type whose name is specified, using the named assembly file and the constructor that best matches the specified parameters.

Creates a proxy for the well-known object indicated by the specified type, URL, and channel data. Retrieves the type information for an object, which can then be used to get the type information for an interface. Skip to main content. This browser is no longer supported.

CreateInstance ActivationContext. I've been using the trick with a generic class implementing a regular interface a lot, it is very powerful.

Cant you just wrap it? WriteLine beerStore. Not loved Not loved How do I call this method? I use Visual Studio and. Net 4. There is no boxing conversion or type parameter conversion from 'T' to 'IStorable'.

Ah you added the where section now. Maybe that made a difference. Let me try again. Show 6 more comments. Most appropriate answer in my opinion would be 'you can't do it in this way'. Snowbear Snowbear As to the other suggestion, besides an instance of the objectThatImplementsIStorable I do not know the actual Type anywhere. I think I'll end up using Reflection on the object that the Activator made. Add a comment. Pang 8, gold badges 82 82 silver badges bronze badges.

Then x cannot be cast to Store, but it can be cast to Store. Uri Uri You cant cast a generic type without including the T, ie Store x wont compile — Not loved. Sign up or log in Sign up using Google. Sign up using Facebook. Sign up using Email and Password.
