The point of the strategy pattern is to isolate the choice of what to do from the doing of it. Let's say you have a UI with a pair of dropdowns, InputType and OutputType, and a button DoConversion.

You can have UI code like

partial class UI { public Converter { get; set; } void onInputTypeCombo_Changed(InputType inputType) { Converter.setInputStrategy(inputType); } void onOutputTypeCombo_Changed(OutputType outputType) { Converter.setOutputStrategy(outputType); } void onDoConversion_Clicked() { Converter.doConversion(); } };

And the Converter will instantiate concrete strategy objects based on the passed InputType and OutputType. But it won't do the conversion until the button is pressed.
