    mystring.split help

    Code:
    Ok as you might of guess from the title i am trying to split a string down to an array with a new 'Ray' ( not sure what the actural tecinal term is for a single line in an array) give every time '{' Appears
    
    this is the script im using 
    Code:
    string[] aryRacelist = strRace.Split('}');
    But im getting an error saying system.IO.Streamreader does not contain a definition for 'Split' So i believe the error lie in i have not reference the proper using System.whatever that contains Split. Can anyone tell me what it is, or have i just gone really wrong. i believe my coding right because i copied it off online example. Anyhelp would be nice
    sry that it all in code bracket, it wouldn't let me post without

    Looks like strRace is a StreamReader and not a string. Usually you would do something like:
    Code:
    using (StreamReader sr = new StreamReader(streamYouWantToRead))
    {
        string line;
        while (null != (line = sr.ReadLine()))
        {
            string[] splitString = line.Split('}');
        }
    }

    Or even simplier:
    Code:
    strRace.ReadToEnd().Split(new char[] { '}' } );
    If you dislike empty lines (like you get if you have "} }"), use this:
    Code:
    strRace.ReadToEnd().Split(new char[] { '}' }, System.StringSplitOptions.RemoveEmptyEntries);

    Code:
    using System;
    using System.Collections.Generic;
    using System.ComponentModel;
    using System.Data;
    using System.Drawing;
    using System.Text;
    using System.Windows.Forms;
    using System.IO;
    
    namespace WindowsApplication2
    {
        public partial class Form1 : Form
        {
            public Form1()
            {
                InitializeComponent();
            }
    
            private void button1_Click(object sender, EventArgs e)
            {
                StreamReader strRace = new StreamReader("Z:\\Homeworld2\\scripts\\race.lua");
                txtCurrent.Text = strRace.ReadToEnd();
                strRace.ReadToEnd().Split(new char[] { '{' });
                lbxRaces.Items.AddRange();   
                strRace.Close();
                
            }
    
            private void Form1_Load(object sender, EventArgs e)
            {
    
            }
    
        }
    }
    and here my error code

    The error message is very clear. The AddRange method of the ListBox class requires an argument.

    Code:
                txtCurrent.Text = strRace.ReadToEnd();
                strRace.ReadToEnd().Split(new char[] { '{' });
    Don't ReadToEnd twice. Use txtCurrent.Text as source in your second line.

    When in doubt, read the FAQ.

    The name is whatever you want it to be, you just assign the result of the split to a string array variable!
    Code:
    string [] races = strRace.ReadToEnd().Split(new char[] { '{' });
    lbxRaces.Items.AddRance(races);

    You don't need to use new string, just get the one that's selected.
    Code:
    string strRacedata = lbxRaces.SelectedItem.ToString();
