Edit and Remove CSV File from code

[MohammedAmine]

Hello NT Team,

I use this code to create a write into a new created csv file :

sw = File.AppendText(path);
sw.WriteLine("Entry Price, " + "Quantity, " + "SL Level, " + "TP Level, " + "Side");
sw.WriteLine(PositionAccount.AveragePrice + "," + QtyMini + "," + ShortSL + "," + ShortTP + "," + "Short");
sw.Close();

This successfully creates a csv file with appropriate value, it looks something like this :

Entry Price	Quantity	SL Level	TP Level	Side
4780.5	4	4789.461	4762.578	Short

Now what I need is to edit these values in the same row if certain conditions are taking place, I've been looking around if exist any method called may be "UpdateLine" or "ReWriteLine" but I didn't find any, can you tell me plz how can I modify the first value for example from "4780.5" to "4950.7" ?

Second things is that I want to remove this excel file at the end of trading day, so is there a method called

sw.Remove();

for example ? I didn't find such thing.

Thank you very much for your help and permanent support

Hello MohammedAmine,

Thanks for your post.

Reading/writing and manipulating CSV files are outside of Ninjascript scope of support

We provide educational examples (below) for anyone that wants to get into reading and writing data files but this is not something we can provide support for (beyond the educational references) and would suggest that you review a C# course to better understand how to use these methods. Here is a link that may get you started with the subject: https://www.tutorialspoint.com/cshar...text_files.htm

To both read and write a file, you may want to review the 3rd example below to get some further ideas.
