I'm having an issue with usnig a foreach loop inside my array declaration for my manual universe selection.  This little issue is tripping me up quite a bit in moving forward, so any help would be really great!!!

string[] arrayofTickers = new string[] {

public override void Initialize()
//General housekeeping and setup
SetStartDate(2018, 1, 15); //Set Start Date
SetEndDate(2018, 7, 15); //Set End Date
SetCash(100000); //Set Strategy Cash

UniverseSettings.Resolution = Resolution.Minute;
maxMinCount = maxDayCount*1440;

//Save number of tickers to a global int for later loop purposes in onData
numTickers = arrayofTickers.Length;

var symbols = new[] //Building list of all tickers for the universe
//foreach loop here? for QuantConnect.Symbol.Create(arrayofTickers[i], SecurityType.Equity, Market.USA)


//Set universe mode selection to manual
SetUniverseSelection(new ManualUniverseSelectionModel(symbols));

//Set all other modules to null
SetAlpha(new NullAlphaModel());
SetPortfolioConstruction(new NullPortfolioConstructionModel());
SetExecution(new NullExecutionModel());
SetRiskManagement(new NullRiskManagementModel());
