UnknownWrapper UnknownWrapper UnknownWrapper UnknownWrapper Class



此 API 现已过时。

对封送处理程序应该将其作为 VT_UNKNOWN 封送的对象进行包装。Wraps objects the marshaler should marshal as a VT_UNKNOWN.

public ref class UnknownWrapper sealed
[System.Obsolete("UnknownWrapper and support for marshalling to the VARIANT type may be unavailable in future releases.")]
public sealed class UnknownWrapper
type UnknownWrapper = class
Public NotInheritable Class UnknownWrapper


仅在方法的托管签名采用对象时适用。Only applies when the managed signature of a method takes an object.

int MyMethod(Object o); //Managed signature  
    HRESULT MyMethod(VARIANT o); //COM signature  
    MyObject o = new MyObject();  
    MyMethod(o); //o gets passed as VARIANT VT_DISPATCH  
    MyMethod(new UnknownWrapper(o)); //o gets passed as VARIANT VT_UNKNOWN
