    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        //public MatchCollection Matches(string input);

        public static string StringStrip(string Text)
        {
            Text = Regex.Replace(Text, "<.*?>", string.Empty);

            return Text;
        }

        private void button1_Click(object sender, EventArgs e)
        {
            //används för att bygga en sträng från ström
            StringBuilder sb = new StringBuilder();

            byte[] buf = new byte[8192];

            HttpWebRequest request = (HttpWebRequest)
                WebRequest.Create("http://rankswebowl.svenskidrott.se/Query.aspx?QueryParm=100|QueryRankPoints DESC,QueryAverage DESC,QueryPlace DESC||1|||||'26768-07'|||||||");

            HttpWebResponse response = (HttpWebResponse)
                requset.GetResponse();

            Steam resStream = response.GetResponseStream();

            string tempString = null;
            int count = 0;

            do
            {
                count = resStream.Read(buf, 0, buf.Length);

                if (count != 0)
                {
                    tempString = Encoding.UTF8.GetString(buf, 0, count);
                    sb.Append(tempString);
                }
            }
            while (count > 0);
            {
                string code = StringStrip(sb.ToString());
            }
        }
    }
}

and i wonder how to take out thing from the string, ex names. someone have an idee of how i do ??

Hi friend, You can use regex expressions to get things from the string. Otherwise if the string fulfills somewhat format, you can split the strings to different arrays. Eg If the string is "Name: jinge, Age:20", you can first split it with comma as separater, then split it with colon. string [] arr = str.split(","); string[] subarr = arr[0].split(":"); string name = subarr[1]; // name will be assigned to jinge.

ben gotch · Answer

Str is the string that you want to do the split on so in the previous example it would be String str = "Name: jinge, Age:20"; string [] arr = str.split(","); string[] subarr = arr[0].split(":"); string name = subarr[1]; // name will be assigned to jinge.
