ronado portugal [3]

C#

OpenFileDialog dialogu = new OpenFileDialog();
            dialogu.Filter = "*.txt|*.txt";
            if (dialogu.ShowDialog() == DialogResult.OK)
            {
                listBox1.DataSource = File.ReadAllText(dialogu.FileName, System.Text.Encoding.Default);

hmmm I used it but doesn't work ??

Solution 2

You need to use Itemsource for List box control. Datasource will not work in WPF

C#

lstBox.ItemsSource = System.IO.File.ReadAllLines(dialogu.FileName, System.Text.Encoding.Default);

You are using winforms is it?

h5h5 23-May-12 9:58am

Yes men, Framework 3.5

Then use Datasource instead. I have just crated a listbox in winforms and its working fine.. What about the file? Did you check File.Readalllines using immediate window? Please check if the data is returned properly from File.ReadAlllines

Hi
Check this

C#

private void button1_Click(object sender, EventArgs e)
{
    OpenFileDialog dialogu = new OpenFileDialog();
    dialogu.Filter = "*.txt|*.txt";
    if (dialogu.ShowDialog() == DialogResult.OK)
    {
        string[] all = File.ReadAllLines(dialogu.FileName, System.Text.Encoding.Default);
        listBox1.DataSource = all;

    }
}

Best Regards

now I want to sort those data like that:
mesu ozil germany [5]
mesi argentina [4]
ronado portugal [3]

so the high value in bracket to be first :
I am using this code but they are not sorting

tring[] sort= listBox1.Items.Cast().ToArray();
List count= (
sort.GroupBy(name => name).OrderByDescending(g => g.Count())
.Select(group => string.Format("{0} [{1}]", group.Key, group.Count())).ToList());
listBox2.DataSource = count
