Controls the marshaling behavior of a delegate signature passed as an unmanaged function pointer to or from unmanaged code. This class cannot be inherited.
Assemblies: System.Runtime.InteropServices (in System.Runtime.InteropServices.dll)
mscorlib (in mscorlib.dll)
Thetype exposes the following members.
|Equals||Infrastructure. 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||When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
|BestFitMapping||Enables or disables best-fit mapping behavior when converting Unicode characters to ANSI characters.|
|CharSet||Indicates how to marshal string parameters to the method, and controls name mangling.|
|SetLastError||Indicates whether the callee calls the SetLastError Win32 API function before returning from the attributed method.|
|ThrowOnUnmappableChar||Enables or disables the throwing of an exception on an unmappable Unicode character that is converted to an ANSI "?" character.|
|_Attribute.GetIDsOfNames||Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)|
|_Attribute.GetTypeInfo||Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.)|
|_Attribute.GetTypeInfoCount||Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)|
|_Attribute.Invoke||Provides access to properties and methods exposed by an object. (Inherited from Attribute.)|
The fields of the attribute control various aspects of the transition of a delegate to an unmanaged function pointer, and are the same as the fields with identical names in the DllImportAttribute attribute. These fields are optional, but if you do not specify a field name, is ignored.
