With what you were trying, even if you did get it to compile/run, it would still be wrong because the Value & Text fields would've been set to a value in the list instead of the property name (ie, DataValueField = "TX"; DataTextField = "Texas"; instead of DataValueField = "stateCode"; DataTextField = "stateName"; like you really want).

public static void populateDropDownList(this DropDownList source,
        IEnumerable dataSource,
        Func dataValueField,
        Func dataTextField) {
    source.DataValueField = dataValueField();
    source.DataTextField = dataTextField();
    source.DataSource = dataSource;
    source.DataBind();
}

myDropDownList.populateDropDownList(states,
        "stateCode",
        "stateName");
