    Hi @MiPakTeh , Welcome to Microsoft Q&A, you could try the following code to get what you wanted.

    It seems to me that you want to get all the information for 3 and 14, you need to change it like this: 

    private void listBox3_SelectedIndexChanged(object sender, EventArgs e)  
{  
	listBox4.Items.Clear();  
	string curItem = listBox3.SelectedItem.ToString().Trim();  
	string[] arr = curItem.Split(' ').Where(i => i != "").ToArray();  
	foreach (var item in arr)  
	{  
		string[] strarr = item.Split(new string[] { "=>" }, StringSplitOptions.None);  
		int index = Convert.ToInt32(strarr[0]);  
  
		for (int i = 12 * index; i < 12 * index + 12; i++)  
		{  
			string listbox1item = listBox2.Items[i].ToString();  
			listBox4.Items.Add(listbox1item);  
		}  
	}  
}

    If you simply want lines 3 and 14. You just need to change string listbox1item = listBox2.Items[index-1].ToString();

    But according to your calculation, if there is an index 0 problem, you need to consider related issues.
