Question

hihi
i have a question that i want to ask about c# and window form

1. i have this data… A,B,C; A1,B1,C1; A2,B2,C2; (this data is not hardcoded, it can continue to change, when more data insert come in) , i select this database column which is name as ColABC , and i retrieve and put in the datagridview ,
   So is possible to always get the middle data?….but it is always this format record1 data, record1 data, record1; record2 data, record3 data, record…and so i want this data all the middle value retrieve out to this become this B,B1,B2…….so on…

   ID |  ColABC
    1 |  A,B,C; A1,B1,C1; A2,B2,C2;
   

This is like my DataGridView, the above.

The only thing i know is use split by ; first then by ,.

Is there any direct way?

Something like this, I try:

string[] doll = null;
doll = Convert.ToString(DGV.CurrentRow.Cells[0].Value).Split(';');

Basically like example the above code, doll get the ” A,B,C; A1,B1,C1; A2,B2,C2; ” this data which i retrieve from datagridview, so if i declare roll[0] it will give me “A,B,C”, like what i mention above the data will change so how am i get the middle value always??

Answer 1

var input = "A,B,C; A1,B1,C1; A2,B2,C2;";
var resultList = Regex.Matches(input, @".*?,(.*?),.*?;")
    .Cast<Match>()
    .Select(arg => arg.Groups[1].Value)
    .ToList();

var firstValue = resultList[0];
var secondValue = resultList[1];

// bind to a combobox
comboBox1.DataSource = resultList;

var comaSeparatedString = string.Join(",", resultList);
