The ImportingConstructorAttribute type exposes the following members.


  Name Description
Public method ImportingConstructorAttribute Initializes a new instance of the ImportingConstructorAttribute class.



  Name Description
Public method Equals Infrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)
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 Returns the hash code for this instance. (Inherited from Attribute.)
Public method GetType Gets the Type of the current instance. (Inherited from Object.)
Public method Match When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)
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.)



By default, only a parameter-less constructor will be used to construct an attributed part. Use ImportingConstructorAttribute to indicate that a specific constructor should be used instead. Parameters to the decorated constructor will be treated as imports.
