Метод	Описание
Contains ( object>.KeyValuePair item, bool includeInstanceProperties = false ) : bool	Checks whether a property exists in the Property collection or as a property on the instance
Expando ( ) : System	This constructor just works off the internal dictionary and any public properties of this object. Note you can subclass Expando.
Expando ( object>.IDictionary dict ) : System	Create an Expando from a dictionary
Expando ( object instance ) : System	Allows passing in an existing instance variable to 'extend'. You can pass in null here if you don't want to check native properties and only check the Dictionary!
GetDynamicMemberNames ( ) : IEnumerable	Return both instance and dynamic names. Important to return both so JSON serialization with Json.NET works.
GetProperties ( bool includeInstanceProperties = false ) : object>>.IEnumerable	Returns and the properties of
TryGetMember ( GetMemberBinder binder, object &result ) : bool	Try to retrieve a member by name first from instance properties followed by the collection entries.
TryInvokeMember ( InvokeMemberBinder binder, object args, object &result ) : bool	Dynamic invocation method. Currently allows only for Reflection based operation (no ability to add methods dynamically).
TrySetMember ( SetMemberBinder binder, object value ) : bool	Property setter implementation tries to retrieve value from instance first then into this object
this ( string key ) : object	Convenience method that provides a string Indexer to the Properties collection AND the strongly typed properties of the object by name. // dynamic exp["Address"] = "112 nowhere lane"; // strong var name = exp["StronglyTypedProperty"] as string; The getter checks the Properties dictionary first then looks in PropertyInfo for properties. The setter checks the instance properties before checking the Properties dictionary.

Описание методов

Contains() публичный Метод

Checks whether a property exists in the Property collection or as a property on the instance

public Contains ( object>.KeyValuePair item, bool includeInstanceProperties = false ) : bool
item	object>.KeyValuePair
includeInstanceProperties	bool
Результат	bool

Expando() публичный Метод

This constructor just works off the internal dictionary and any public properties of this object. Note you can subclass Expando.

public Expando ( ) : System
Результат	System

Expando() публичный Метод

Create an Expando from a dictionary

public Expando ( object>.IDictionary dict ) : System
dict	object>.IDictionary
Результат	System

Expando() публичный Метод

Allows passing in an existing instance variable to 'extend'.

You can pass in null here if you don't want to check native properties and only check the Dictionary!

public Expando ( object instance ) : System
instance	object
Результат	System

GetDynamicMemberNames() публичный Метод

Return both instance and dynamic names. Important to return both so JSON serialization with Json.NET works.

public GetDynamicMemberNames ( ) : IEnumerable
Результат	IEnumerable

GetProperties() публичный Метод

Returns and the properties of

public GetProperties ( bool includeInstanceProperties = false ) : object>>.IEnumerable
includeInstanceProperties	bool
Результат	object>>.IEnumerable

GetProperty() защищенный Метод

Reflection Helper method to retrieve a property

protected GetProperty ( object instance, string name, object &result ) : bool
instance	object
name	string
result	object
Результат	bool

Initialize() защищенный Метод

protected Initialize ( object instance ) : void
instance	object
Результат	void

InvokeMethod() защищенный Метод

Reflection helper method to invoke a method

protected InvokeMethod ( object instance, string name, object args, object &result ) : bool
instance	object
name	string
args	object
result	object
Результат	bool

SetProperty() защищенный Метод

Reflection helper method to set a property value

protected SetProperty ( object instance, string name, object value ) : bool
instance	object
name	string
value	object
Результат	bool

TryGetMember() публичный Метод

Try to retrieve a member by name first from instance properties followed by the collection entries.

public TryGetMember ( GetMemberBinder binder, object &result ) : bool
binder	System.Dynamic.GetMemberBinder
result	object
Результат	bool

TryInvokeMember() публичный Метод

Dynamic invocation method. Currently allows only for Reflection based operation (no ability to add methods dynamically).

public TryInvokeMember ( InvokeMemberBinder binder, object args, object &result ) : bool
binder	System.Dynamic.InvokeMemberBinder
args	object
result	object
Результат	bool

TrySetMember() публичный Метод

Property setter implementation tries to retrieve value from instance first then into this object

public TrySetMember ( SetMemberBinder binder, object value ) : bool
binder	System.Dynamic.SetMemberBinder
value	object
Результат	bool

this() публичный Метод

Convenience method that provides a string Indexer to the Properties collection AND the strongly typed properties of the object by name. // dynamic exp["Address"] = "112 nowhere lane"; // strong var name = exp["StronglyTypedProperty"] as string;

The getter checks the Properties dictionary first then looks in PropertyInfo for properties. The setter checks the instance properties before checking the Properties dictionary.

public this ( string key ) : object
key	string
Результат	object

Описание свойств

Properties публичное свойство

String Dictionary that contains the extra dynamic values stored on this object/instance

Using PropertyBag to support XML Serialization of the dictionary

public PropertyBag Properties
Результат	PropertyBag
