Examples of StreamWriter / StreamReader ?

[pstrusi]

At the day's end, in my strategy, I have certain data organized as a simple array that I'd like to write to a file so this file can be read once again when the new session begins. I've been searching and reading about the use of : StreamWriter and StreamReader on the microsoft site but it's hard to understand all that formal way to explain without clear examples.

Could you please indicate me where can I see some examples in order to be able to write and read this type of data files?

Thanks

Hi pstrusi, thanks for posting. We have a few examples for studying. I have linked them below.

I'm looking for something similar to this:

using System.IO;
using System;
public class Program {
   public static void Main() {
      string[] stringArray = new string[] {
         "one",
         "two",
         "three"
      };
      File.WriteAllLines("new.txt", stringArray);
      using (StreamReader sr = new StreamReader("new.txt")) {
         string res = sr.ReadToEnd();
         Console.WriteLine(res);
      }
   }
}​

Hi pstrusi, thanks for posting. We have a few examples...........

Thanks for answering ChrisL, but unfortunately it doesn't address the request. First, I wrote for the NT7 forum, not NT8, although they have similar guides ( by the way, all the links in the NT8 leads to an empty web page, error 404 ) . Second, at the final it gave the same useless example, working with indicators with a file of Strings. This is the link for NT7: https://ninjatrader.com/support/help...ce_samples.htm


I just need to write in my disk, a data array that comes from a running strategy.
In case you find some better idea, please let me know.

Thanks

Hi pstrusi, sorry for the oversight. The example is still basically the same since this is a C# library (StreamWriter) we are using to write to a file The only difference here is the setup where path is set up and OnStateChange() is similar to Initialize() in NinjaTrader 7. I'm not getting a 404 error on the links that I posted, your browser might not be pointing to the correct URL.

Kind regards,

Since I consider that being able to write/read a data file for a Strategy use might be useful, I'm working to find a method for this and then letting know it in this forum.
