Question

I have a string array. It is dynamic and can be of any length(0 also). How can I make a single string from the array, delimited by any separator like ; or | ??

string str = string.empty;
string[] arrOptions = strOptions.Split(new string[]{"\n"}, StringSplitOptions.RemoveEmptyEntries);

Now, have to make the string from arrOptions and put it in str

You can try both way:

    string[] strArr = { "Abc", "DEF", "GHI" };

    //    int i = 0;
    //    string final=string.Empty;
    //IterationStart:
    //    if (i < strArr.Length)
    //    {
    //        final += strArr[i] + ",";
    //        i++;
    //        goto IterationStart;
    //    }
    //Console.WriteLine(final);

     string str = string.Join(",", strArr);
     Console.WriteLine(str);
