I'm sure English is not your native language, but it is the default language for this site.
In English, your question makes no sense at all.
Please, either try to find a better translation of your question to English, or find a site in your own native language, as they may be able to help you better than we can!

If a person wants to store "large quantities of zero", learning English more will hardly help... :-)

Perfectly agreed. I wish I could give you a +5 here :-). Still one might try learning. Hope these links help:

I dunno, I have an infinite capacity of WOM fitted to this PC - it can hold *huge* quantities of zero without any strain. :laugh:
Yes, you can. I'm talking about someone who can see a problem storing it and needs an advice on it... :-)

I'd avoid using XML, something that maintains the link between the XML structure and the information held would look like:

<?xml version="1.0"?>

The xml is much bigger than the information it contains and problem becomes worse if you are storing bits/bools rather than ints.
Pesonally, as chromosome information is so basic, you could write directly to disk in csv format.

As the CSV format is so simple, I'd do something like this:

public class Chromosome
  char delimiter = ',';
  public List<int> Genes 
     private set;
  public override ToString()
    StringBuilder sb = new StringBuilder();
    foreach(int gene in Genes)
    return sb.ToString().Trim(delimiter);
  public void ReadString(string csv)
    var items = string.split(delimiter);
    foreach (string item in items)
       Genes.Add(int.Parse(item)); //Note this can throw if non-int passed.

I've not tested the above, but you should get the idea. Then all you need do is write to file if required. Google c# streamreader and c# streamwriter for more info.
One thing about my code is that it leaves the serialization in the class, this is not an ideal solution, so you should separate it out. The other thing you could consider is a Custom Serializer[^]
