## ObjectExt class


Provides static methods that emulate C# [Object](../object/) methods called for non-Object C++ types (strings, numbers, etc.). This is a static type with no instance services. You should never create instances of it by any means.

```cpp
class ObjectExt : public System::ObjectType
```
