InitializeComponent();

}

private void button1_Click(object sender, EventArgs e)

Hi,Before you can check directly in browers url contains data or not.

try my sample url image file

System.Net.WebClient wc = new System.Net.WebClient();
byte[] raw = wc.DownloadData("http://adrenalin.myadrenalin.com/myadrenalin/images/login.jpg");
string webData = System.Text.Encoding.UTF8.GetString(raw);

It will return data.
