How can I convert mql4 from c #?

[Mehmet Bastem]

Dictionary<string, List<string>> dic = new Dictionary<string, List<string>>();
            List<string> myValues1 = new List<string>();
            for (int i = 0; i < 50; i++)
            {
                myValues1.Add("KeyA" + i);
            }

            List<string> myValues2 = new List<string>();
            for (int i = 0; i < 50; i++)
            {
                myValues2.Add("KeyB" + i);
            }


            List<string> myValues3 = new List<string>();
            for (int i = 0; i < 50; i++)
            {
                myValues3.Add("KeyC" + i);
            }



            dic.Add("A", myValues1);
            dic.Add("B", myValues2);
            dic.Add("C", myValues3);

            foreach (KeyValuePair<string, List<string>> pair in dic)
            {
                string pk = pair.Key.ToString();

                if (pair.Key == "A")
                {
                    foreach (string d in pair.Value)
                    {
                        MessageBox.Show("Key:" + pair.Key.ToString() + "      Değeri: " + d.ToString());
                    }
                }


            }

You might look into the standard libraries if you find Dictionary and List equivalents implemented (I do not know the standard library). If not, you have to implement yours like many did. Below there is your example with use of my implementation.

1. Play video	Please edit your post. For large amounts of code, attach it

   ---

2. Not MQL4 code
   
3. No question asked
   
4. You have only four choices:
   • Search for it,
   • learn to code it,
   • beg at Coding help - General - MQL5 programming forum or Need help with coding - General - MQL5 programming forum or Free MQL4 To MQL5 Converter - General - MQL5 programming forum,
   • or pay (Freelance) someone to code it.
   We're not going to code it for you (although it could happen if you are lucky or the problem is interesting.) We are willing to help you when you post your attempt (using SRC) and the nature of your problem.

 too long code ?.

 string b11[20];

   string SeyranGrup[20]={"aa","bb","cc","dd"};

   b11[2]="Seyran"+"Grup[2]";

   Alert(b11[2]);

result is SeyranGrup[2], i want to  result is "cc".

It does not look like C# code. You should open a new thread. Those, who could answer your query, would not enter a C# related thread.
