I have error
Cannot access a non-static member of outer type \'Project.Neuro\' via nested type \'Project.Neuro.Net\'
with cod
you need to instantiate an object of type Neuro somewhere in your code and call OtherMethod on it, since OtherMethod is not a static method. Whether you create this object inside of SomeMethod, or pass it as an argument to it is up to you. Something like:
// somewhere in the code
var neuroObject = new Neuro();
// inside SomeMethod()
int x = neuroObject.OtherMethod();
alternatively, you can make OtherMethod static, which will allow you to call it from SomeMethod as you currently are.
