StreamReader多行

Question

I am trying to figure out how to read multiple lines whith StreamReader. I have a text file with a list of commands inside it that I need to read from. My code works, however it will only read the first line. This causes me to have to move all my commands to a single line with a space between them. This is not a very tidy way of doing this seeing as I need to leave comments next to the commands. Example: CONNECT: "Connects to given IP."

public void ConsoleEnter_KeyDown(object sender, KeyEventArgs e)
    {
        string line;
        if (e.KeyCode == Keys.Enter)
        {

            // Read the file and display it line by line.
            StreamReader file = new StreamReader("C:\\Users\\Home\\Desktop\\commands.txt");
            while ((line = file.ReadLine()) != null)
            {
                if (line.Contains(ConsoleEnter.Text))
                {
                    COMBOX.Items.Add(ConsoleEnter.Text);
                    COMBOX.Items.Remove("");
                    ConsoleEnter.Text = "";
                }
                else
                {
                    COMBOX.Items.Add("Invalid Command");
                    COMBOX.Items.Remove("");
                    ConsoleEnter.Text = "";

                }
            }
        }
    }

u should empty the variable after the loop, not inside the loop

public void ConsoleEnter_KeyDown(object sender, KeyEventArgs e)
    {
        string line;
        if (e.KeyCode == Keys.Enter)
        {

            // Read the file and display it line by line.
            StreamReader file = new StreamReader("C:\\Users\\Home\\Desktop\\commands.txt");
            while ((line = file.ReadLine()) != null)
            {
                if (line.Contains(ConsoleEnter.Text))
                {
                    COMBOX.Items.Add(ConsoleEnter.Text);
                }
                else
                {
                    COMBOX.Items.Add("Invalid Command");
                }
            }
            COMBOX.Items.Remove("");
            ConsoleEnter.Text = "";
        }
    }

public void ConsoleEnter_KeyDown(object sender, KeyEventArgs e)
 {
    string line;
    string path = @"C:\\Users\\Home\\Desktop\\commands.txt";
     WebClient client = new WebClient();
     System.IO.Stream stream = client.OpenRead(path);
     System.IO.StreamReader str = new StreamReader(stream);
         string Text=str.ReadToEnd();    
         string[] words = Text.Split(':');   


      if (e.KeyCode == Keys.Enter)
       {

       for(int i=1;i<words.Length;i++)
            {  
               if (string.compare(words[i],textBox1.text)==0)
              {
                COMBOX.Items.Add(ConsoleEnter.Text);
                COMBOX.Items.Remove("");
                ConsoleEnter.Text = "";
               }
            else
             {
                COMBOX.Items.Add("Invalid Command");
                COMBOX.Items.Remove("");
                ConsoleEnter.Text = "";

             }

        }
    }
}

try this .. use namespace using System.Net;

This is what am using in one of my app and its working fine hope it'll help you out.......

                if (TxtPath.Text != string.Empty)
                 {
                  StreamReader srr = new StreamReader(TxtPath.Text);
                    try
                    {
                        ss = srr.ReadToEnd().Split('\n');
                        MessageBox.Show("File Successfully Loded in Memory \n" + TxtPath.Text, "System Manager", MessageBoxButtons.OK, MessageBoxIcon.Information);
                    }
                    catch (Exception)
                    {

                        throw new Exception("File are not readable or write protacted");
                    }
                    LblLineCount.Text = ss.Count().ToString();
                }
                else
                {
                    MessageBox.Show("Please Browse any Log File 1st", "System Manager", MessageBoxButtons.OK, MessageBoxIcon.Stop);
                }

you can also trim the .Split('\\n') to take all data in single line, i can't try it right now but if check it will get u out of stuck...........
