Question

Is it possible to invoke a method based of a text value?

I don’t want to use ‘if’ or ‘switch’ statements if possible.

If so what do i need to look at to do this?

This is just to try and cleanup an interface.

Example with if statement:

    if (cmb_Motor.SelectedItem.ToString() == "OutPortA")
             NXT_Brick.OutPortA.SetOutputState();
    else if (cmb_Motor.SelectedItem.ToString() == "OutPortB")
             NXT_Brick.OutPortB.SetOutputState();
    else if (cmb_Motor.SelectedItem.ToString() == "OutPortC")
             NXT_Brick.OutPortC.SetOutputState();

I want to change the ‘OutPortA,B,C’ after ‘NXT_Brick’.

Answer 1

if and switch statments could be hidded in a dictionary, for example:

private IDictionary<string, OutPort> ports = new Dictionary<string, OutPort>{
  {"OutPortA", NXT_Brick.OutPortA},
  {"OutPortB", NXT_Brick.OutPortB},
  {"OutPortC", NXT_Brick.OutPortC}
}

usage:

if(ports.Contains(key))
{
 ports[key].SetOutputState();
}
