ListView not display column and row in c#

Question

I have array of byte in C# and I want to represent array component as listview. I wrote this code but not display anything.
What is the error I am having which makes viewlist not to show anything?

private void loadToolStripMenuItem_Click(object sender, EventArgs e)
{
    byte[] bmp = File.ReadAllBytes(str);

    ListView listView1 = new ListView();
    listView1.View = View.Details;            
    listView1.FullRowSelect = true;
    listView1.GridLines = true;

    listView1.Columns.Add("Header Information",20);
    listView1.Columns.Add("Description",20);

    char x = (char)bmp[0];
    char y = (char)bmp[1];
    string st = null;
    st += st + x + y;
    listView1.Items.Add(st, 0);
    listView1.Items.Add("signature", 1);

    num = Convert.ToInt32(bmp[2]);
    str = num.ToString();
    listView1.Items.Add(str, 0);
    listView1.Items.Add(" bytes size of BMP in Bytes", 1);

    num = Convert.ToInt32(bmp[10]);
    str = num.ToString();
    listView1.Items.Add(str, 0);
    listView1.Items.Add(" bytes offset to start of image data", 1);
}

You need to add this control to your form or panel like below

Controls.Add(listView1);

or

YourPanelName.Controls.Add(listView1);

if you have already added listview by designer ( e.g. named as ListView1)

then you don't need to create new list view, you can directly add items

//ListView listView1 = new ListView();
listView1.View = View.Details;            
listView1.FullRowSelect = true;
listView1.GridLines = true
listView1.Columns.Add("Header Information",20);
listView1.Columns.Add("Description",20);
listView1.Items.Add(new ListViewItem(new string[] {"Information", "Description"}));
