UnknownWrapper 类

定义

命名空间:

System.Runtime.InteropServices

程序集:

System.Runtime.InteropServices.dll

程序集:

mscorlib.dll

程序集:

netstandard.dll

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

Public NotInheritable Class UnknownWrapper

属性

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  

构造函数

UnknownWrapper(Object)

使用要被包装的对象初始化 UnknownWrapper 类的新实例。

属性

GetHashCode()	作为默认哈希函数。 (继承自 Object)
GetType()	获取当前实例的 Type。 (继承自 Object)
MemberwiseClone()	创建当前 Object 的浅表副本。 (继承自 Object)
ToString()	返回表示当前对象的字符串。 (继承自 Object)
