        Static voidMain (string[] args) {            stringstr ="Hello world! "; stringNewstr =Str.            Trim (); string[] s = str. Split (New Char[] {' '}, Stringsplitoptions.removeemptyentries); stringSS =string. Join (" ", s);            Console.WriteLine (ss);        Console.readkey (); }

3.

Make a console applet. Requirements: The user can enter the name of each student in the console, and when the user enters quit(case insensitive), the program stops accepting the user's input and displays the number of students entered by the user, as well as the name of each student.

        Static voidMain (string[] args) {List<string> namelist =Newlist<string>();  while(true) {Console.WriteLine ("Please enter your name:"); stringName =Console.ReadLine ();                Namelist.add (name); if(name. ToLower ()) = ="quit")                {                     Break; }} Console.WriteLine ("you entered a total of: {0} Students, the names are:", Getnamesnum (NameList)-1);  for(inti =0; I < namelist.count-1; i++) {Console.WriteLine (namelist[i]);        } console.readkey (); }        /// <summary>        ///iterating through a collection of strings/// </summary>        /// <param name= "names" >the collection to traverse</param>        /// <returns>returns the number of elements in a collection</returns>        ///        Static intGetnamesnum (list<string>names) {            returnnames.
