The array isnt initialized.
Try using List instead of array.
private void button2_Click(object sender, EventArgs e)
{
List<int> citaj = new List<int>();
string h;
using(System.IO.StreamReader sr = new System.IO.StreamReader(@"text\brojac.txt"))
{
while ((h = sr.ReadLine()) != null)
{
int number = 0;
if (int.TryParse(h, out number))
citaj.Add(number);
}
}
}
solved How can i read from a text file line by line and add those strings to an array? [closed]
