How do I call a method from another controller?

I have a couple of reusable methods GetChartData() and GetPeopleData(). They are stored in a controller called CentralData.cs

I would like to be able to call any one of these methods from a different controller but I'm not sure how I would do that. Does anyone know how I call a method that is located in another controller?

If the method was in the same class it would be as simple as:

MyMethod()
{
    GetChartData();
}

So if the method is in a different controller and as sucha different class, how do I call it?

If you mean that you have 2 controller classes: Controller and OtherController, then you can access a method located in the second class from the first class like this:

class Controller
{
    public void MethodA()
    {
        OtherController.MethodB(); // This will work because MethodB is static
        // Like shown above you can call a static method from anywhere
    }
}

class OtherController
{
    public static void MethodB() // <-- Notice "static"
    {
        // Do stuff
    }
}

I hope this is what you were looking for and that this was a sufficient explaination. If I am too unclear, then just ask what's confusing.

You can only call a non-static method from another class if you have a reference of the object.
If you create the second controller somewhere in the first controller, like: 

ButtonClick(object Sender, EventArgs e) {
    CentralData c = new CentralData();
}

you can simply save that reference in a private variable and lateron say

MyMethod()
{
    c.GetChartData();
}

If you create both of them in another class you have to pass the CentralData object to your other Controller like

public static void Main() {
    CentralData c = new CentralData();
    WindowController w = new WindowController(c);
}

or

public static void Main() {
    CentralData c = new CentralData();
    WindowController w = new WindowController();
    w.c = c;
}

You can create an object of Controller and call the function like a simple class. I do not think any problems with this approach. After all, a controller is just a class. e.g.,

MyController obj = new MyController();
obj.MyFunction();
