Winform Column list

I'm very new to programming so apologies if this is a very obvious question. Ive searched online but not found an answer that quite fits yet.

I am writing a programme that interprets bytes from an index within a filestream. Once they have been converted into human readable dates/strings/ints etc I wanted to use a Winform to display the results in columns. Currently I using a listbox and just dispalying each entry seperated by columns but this feels lile a very clunky way of doing it.

Can someone please suggest how I might go about placing the results into a display that uses columns?

It's better to use a ListView than a ListBox in your case. Here's an example showing all words in a string in separate columns in a ListView:

Make sure following property is set to your ListView (here the Name is ColumnsListView):

ColumnsListView.View = View.Details;

This method takes a string, splits it by space and adds a column for each of the values:

private void SetListView(string input)
{
    var values = input.Split(' ');
    ColumnsListView.Columns.Add("Column1");
    var item = new ListViewItem(values[0]);

    for (var i = 1; i < values.Length; i++)
    {
        ColumnsListView.Columns.Add("Column" + (i+1));
        item.SubItems.Add(new ListViewItem.ListViewSubItem { Text = values[i] });
    }

    ColumnsListView.Items.Add(item);
}

This can be done differently when using LinQ's Skip() method to add the item with subitems:

private void SetListView(string input)
{
    var values = input.Split(' ');

    for (var i = 0; i < values.Length; i++)
        ColumnsListView.Columns.Add("Column" + (i + 1));

    var item = new ListViewItem(values[0]);
    item.SubItems.AddRange(values.Skip(1).ToArray());
    ColumnsListView.Items.Add(item);
}

Update:

Here's an example in case you want to use a DataGridView:

private void SetDataGridView(string input)
{
    var values = input.Split(' ');

    for (var i = 0; i < values.Length; i++)
        ColumnsDataGridView.Columns.Add("Column" + (i + 1), "Column" + (i + 1));

    ColumnsDataGridView.Rows.Add(values);
}
