Methods

  Name Description
Public method Bind(DynamicMetaObject, array<DynamicMetaObject[]) When overridden in the derived class, performs the binding of the dynamic operation.
Public method Bind(array<Object[], ReadOnlyCollection<ParameterExpression>, LabelTarget) Performs the runtime binding of the dynamic operation on a set of arguments. (Overrides CallSiteBinder.Bind(array<Object[], ReadOnlyCollection<ParameterExpression>, LabelTarget).)
Public method BindDelegate<T> Provides low-level runtime binding support. Classes can override this and provide a direct delegate for the implementation of rule. This can enable saving rules to disk, having specialized rules available at runtime, or providing a different caching policy. (Inherited from CallSiteBinder.)
Protected method CacheTarget<T> Adds a target to the cache of known targets. The cached targets will be scanned before calling BindDelegate to produce the new rule. (Inherited from CallSiteBinder.)
Public method Defer(array<DynamicMetaObject[]) Defers the binding of the operation until later time when the runtime values of all dynamic operation arguments have been computed.
Public method Defer(DynamicMetaObject, array<DynamicMetaObject[]) Defers the binding of the operation until later time when the runtime values of all dynamic operation arguments have been computed.
Public method Equals(Object) Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected method Finalize Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
Public method GetHashCode Serves as a hash function for a particular type. (Inherited from Object.)
Public method GetType Gets the Type of the current instance. (Inherited from Object.)
Public method GetUpdateExpression Gets an expression that will cause the binding to be updated. It indicates that the expression's binding is no longer valid. This is typically used when the "version" of a dynamic object has changed.
Protected method MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
Public method ToString Returns a string that represents the current object. (Inherited from Object.)

Remarks

The CallSiteBinder performs the binding of the dynamic operation using the runtime values as input. On the other hand, the DynamicMetaObjectBinder participates in the DynamicMetaObject binding protocol.
