Howto modify DXF codes inside entities?

For example I need change only DXF 30 inside polyline without using API.

What do you mean "without using API"?

Hatch modified by the API (Elevation - DXF code 10) was not physically at a preset level. I saved the DWG file to DXF file. Hatch had a DXF code 10 set, but the code 30 had a value that reflects the actual position. I would like to change code DXF directly.

With help of P/Invoke next functions you can do it:
acdbGetAdsName
acdbEntGet
acdbEntMod
acdbEntUpd

Is the p / invoke is portable between different versions of AutoCAD?

You can do it portable if you check AutoCAD version (Application.Version) and x86/x64

Would you give an example of how to do this in C# ?
