in c++ i can do :

auto objects = std::vector<Object>();
for(auto& obj : objects) {...} // here i can modify obj (move, remove etc)
for(auto obj : objects) {...} // here i can't move/delete obj from objects

auto objects = std::vector<Object>();
for(auto& obj : objects) {...} // here i can modify obj (move, remove etc)
for(auto obj : objects) {...} // here i can't move/delete obj from objects

From what i know, in C# this doesn t allow me to remove, move, modify objects.

var objects = new List<Object>();
foreach(var obj in objects) {...}

var objects = new List<Object>();
foreach(var obj in objects) {...}

How can i do something like this for(auto& obj : objects) without having to use indices?

You pretty much have to use indices Lists specifically do not allow you to modify them during enumeration

In what way do you want to modify the object?

in any way let s say to move it to the end

I ask this because there's several ways you could do things when it's vague, for example doing LINQ to map the list to what you want Move the first object to the end? So you mean a Queue<T> would fit better
