Like this

string[]  strarry = [12, 34, A1, FE, 12, 34, EA, 0, FE]

12 is the beginning , FE is the end, Turn into

string strarry = [[12,34,A1,FE],[12,34,EA,0,FE]];

The length from 12 to Fe is not necessarily

How can I do it? Thank you

If I've understood you right (you want to obtain jagged array string[][] from ordinal one - string[]), you can try Linq in order to GroupBy items into subarrays:

  using System.Linq;

  ...

  string[] strarry = new string[]
    {"12", "34", "A1", "FE", "12", "34", "EA", "0", "FE"};

  // Here we exploit side effects, be careful with them
  int groupIndex = 0;

  string[][] result = strarry
    .GroupBy(value => value == "FE" ? groupIndex   : groupIndex)
    .Select(group => group.ToArray())
    .ToArray();

Let's have a look:

  string report = string.Join(Environment.NewLine, result
    .Select(line => "["   string.Join(", ", line)   "]"));

Outcome:

[12, 34, A1, FE]
[12, 34, EA, 0, FE]

I am not sure how applyable this code is for you, but maybe it gets you somewhere. Best of luck!

        var strarry = "12, 34, A1, FE, 12, 34, EA, 0, FE";
        var splittedArrays = strarry.Split(", FE", StringSplitOptions.RemoveEmptyEntries);

        for (int i = 0; i < splittedArrays.Length; i  )
        {
            if (splittedArrays[i][0].Equals(','))
            {
                splittedArrays[i] = splittedArrays[i].Substring(2);
            }

            splittedArrays[i]  = ", FE";
            Console.WriteLine(splittedArrays[i]);
        }
