注意

UnknownWrapper and support for marshalling to the VARIANT type may be unavailable in future releases.

对封送处理程序应该将其作为 VT_UNKNOWN 封送的对象进行包装。

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
public sealed class UnknownWrapper
[System.Runtime.InteropServices.ComVisible(true)]
[System.Serializable]
public sealed class UnknownWrapper
[<System.Obsolete("UnknownWrapper and support for marshalling to the VARIANT type may be unavailable in future releases.")>]
type UnknownWrapper = class
type UnknownWrapper = class
[<System.Runtime.InteropServices.ComVisible(true)>]
[<System.Serializable>]
type UnknownWrapper = class

注解

仅当方法的托管签名采用 对象时适用。

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
