.NET: How do I determine if an object is a COM object?

How do I de开发者_Python百科termine if an object is a COM object? I need to call Marshal.FinalReleaseComObject on all COM objects in an array of type Object.

---

Marshal.IsComObject

---

typeof(myObject).IsCOMObject

or

instanceOfMyObject.GetType().IsCOMObject

---

You can call GetType() and inspect the IsCOMObject property
