Usage

varsubMenu=newConsoleMenu(args,level:1).Add("Sub_One",()=>SomeAction("Sub_One")).Add("Sub_Two",()=>SomeAction("Sub_Two")).Add("Sub_Three",()=>SomeAction("Sub_Three")).Add("Sub_Four",()=>SomeAction("Sub_Four")).Add("Sub_Close",ConsoleMenu.Close).Configure(config =>{config.Selector="--> ";config.EnableFilter=true;config.Title="Submenu";config.EnableBreadcrumb=true;config.WriteBreadcrumbAction= titles =>Console.WriteLine(string.Join(" / ",titles));});varmenu=newConsoleMenu(args,level:0).Add("One",()=>SomeAction("One")).Add("Two",()=>SomeAction("Two")).Add("Three",()=>SomeAction("Three")).Add("Sub",subMenu.Show).Add("Change me",(thisMenu)=>thisMenu.CurrentItem.Name="I am changed!").Add("Close",ConsoleMenu.Close).Add("Action then Close",(thisMenu)=>{SomeAction("Close");thisMenu.CloseMenu();}).Add("Exit",()=>Environment.Exit(0)).Configure(config =>{config.Selector="--> ";config.EnableFilter=true;config.Title="Main menu";config.EnableWriteTitle=true;config.EnableBreadcrumb=true;});menu.Show();

Running app from console with pre-selected menu items

To do this, use public ConsoleMenu(string[] args, int level) constructor during initialization. Use double quotes for item names and digits for item numbers. Here are some examples:

--menu-select=0.1//run first at level 0 and second at level 1--menu-select="Sub.Sub_One.'Close...'"//run "Sub" at level 0 and "Sub_One" at level 1, and "Close..." at level 2--menu-select="Sub.2"//run item "Sub" at level 0, and then run third item at level 1

Configuration

You can also define configuration via .Configure() method. The default config looks like:

publicclassMenuConfig{publicConsoleColorSelectedItemBackgroundColor=Console.ForegroundColor;publicConsoleColorSelectedItemForegroundColor=Console.BackgroundColor;publicConsoleColorItemBackgroundColor=Console.BackgroundColor;publicConsoleColorItemForegroundColor=Console.ForegroundColor;publicEncodingInputEncoding=Console.InputEncoding;publicEncodingOutputEncoding=Console.OutputEncoding;publicActionWriteHeaderAction=()=>Console.WriteLine("Pick an option:");publicAction<MenuItem>WriteItemAction= item =>Console.Write("[{0}] {1}",item.Index,item.Name);publicstringSelector=">> ";publicstringFilterPrompt="Filter: ";publicboolClearConsole=true;publicboolEnableFilter=false;publicstringArgsPreselectedItemsKey="--menu-select=";publiccharArgsPreselectedItemsValueSeparator='.';publicboolEnableWriteTitle=false;publicstringTitle="My menu";publicAction<string>WriteTitleAction= title =>Console.WriteLine(title);publicboolEnableBreadcrumb=false;publicAction<IReadOnlyList<string>>WriteBreadcrumbAction= titles =>Console.WriteLine(string.Join(" > ",titles));publicboolEnableAlphabet=false;}

Example:

newConsoleMenu().Add("One",()=>SomeAction("One")).Add("Two",()=>SomeAction("Two")).Add("Close",ConsoleMenu.Close).Configure(config =>{config.Selector="--> ";}).Show();
