Is C# code freely convertible to C++?

Question

.NET

Good afternoon,
I work closely with 3d graphics (3ds Max), I have experience in communicating with some web programming languages ​​(JS, PHP, etc.). For 3d, you need to work with Unity3d (C#) and (or) Unreal (C++) game engines (I choose now), I also know that C# is in many ways close to Java, which I also like as the idea of ​​​​universalizing the approach to programming. But since C-like languages ​​​​have never come across the question in any form: if the platform (for example, Unreal Engine) specifies C ++ in the language requirements, does this mean that I can make my project in C #, and then calmly convert it in Visual Studio in C++. Does Visual Studio allow this kind of flexibility? Are there pitfalls? Thank you for good links. Also very interested in the experience of developers under Unreal.
Thanks in advance!

Answer 1

In the form in which you need - no, they are not. Syntactically, these languages ​​are similar, but it is impossible to automagically convert and work properly.

Answer 2

No, these languages ​​are completely different and not at all similar to each other.

Answer 3

Theoretically, it is possible to compile a C# project, disassemble the assembly with a reflector with the c ++ / CLI plugin, finish the resulting sources with a file.

1) Use C# to script in Unreal Engine 4 now, courtesy of Xamarin.
2) https://mono-ue.github.io.
I have not tried it myself, but my friends (game developers on UE 4) say that there is a plug-in for this matter.
On Unity3D, for example, this C # is not so much needed, basically the difficulties go through Unity3D bells and whistles (in my case).
