How to make this work, I cant call the string in a different method, please help RRS feed

  • Question

  •  static string[] x = {"Бургас","Варна","Силистра","Търговище","Ловеч",
                 "Кърджали","Пловдив","Благоевград","Пазарджик","Асеновград","Ботевград","Велико Търново","Габрово",
                "Димитровград","Копривщица",  "Крумовград",  "Кърджали" };
            static void Print(string[] a)
                for (int i = 0; i < a.Length; i++)
                    string element = a[i];
                    Console.WriteLine(i+1+": "+a[i]);
            public static void SolveB(string[] a)

                string part = "град";
                bool show =x.Contains(part);
                int firstCharacter = x.IndexOf(part);

                Console.WriteLine("First occurrence: {0}", firstCharacter,part);



      I want the string x to be recongnised by the indexOf so it can make the words which contains that part of the word but i cant make it work

  • Note that x is not a string as you claim, but rather it is an array of strings. The array does not contain any method called "IndexOf", and therefore your code produces a compilation error in the line where you write  int firstCharacter = x.IndexOf(part). The rest of the code compiles correctly.

    You should review what you are trying to do, and ensure that you call IndexOf on a single string, not on the whole array of strings.

  • You should use Linq.

  • using System;
    using System.Linq;

           string[] x = {"one","two","three","four" };

           var myList = x.ToList();

                var position =  myList.IndexOf("two");
