Used to specify each type of result; for functions having various result types.

public ref class ResultTypeAttribute sealed : Attribute

[System.AttributeUsage(System.AttributeTargets.Method, AllowMultiple=true)]
public sealed class ResultTypeAttribute : Attribute

[<System.AttributeUsage(System.AttributeTargets.Method, AllowMultiple=true)>]
type ResultTypeAttribute = class
    inherit Attribute

Public NotInheritable Class ResultTypeAttribute
Inherits Attribute

Inheritance: Object

Attribute
ResultTypeAttribute

Attributes: AttributeUsageAttribute

Remarks

This attribute applies to functions returning various result types. It is used to declare the possible result types returned from the function. For inheritance types, only the root type of the inheritance hierarchy needs to be specified.

See ResultTypeAttribute.Type.

Constructors

ResultTypeAttribute(Type)

Initializes a new instance of the ResultTypeAttribute class.

Properties

Type	Gets the valid or expected type mapping for a function having various result types.
TypeId	When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute)

Methods

Equals(Object)	Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute)
GetHashCode()	Returns the hash code for this instance. (Inherited from Attribute)
GetType()	Gets the Type of the current instance. (Inherited from Object)
IsDefaultAttribute()	When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute)
Match(Object)	When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
ToString()	Returns a string that represents the current object. (Inherited from Object)

Explicit Interface Implementations

_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)	Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute)
_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)	Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute)
_Attribute.GetTypeInfoCount(UInt32)	Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute)
_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)	Provides access to properties and methods exposed by an object. (Inherited from Attribute)
