This part of my C# tutorial is based completely on File I/O. We’ll learn how to Mess with Directories, Use File to Read and Write to Files, Get File Info, Use FileStream, Use StreamWriter, Use BinaryWriter & BinaryReader, and much more.
For best results take notes on the cheat sheet provided above as you watch and leave any questions you have.

You are great. Thanks for teach us.
Is it possible to create and write to a text document as a different user? I'm building a digital forensic challenge creation toolkit using C# and powershell. I require the use of administration access to manipulate the flow of time within the toolkit however I would be interested if it were possible to write files as a standard user using the system.io library. I can achieve this using powershell however, the Lochard Principal really puts pressure on my design to limit any potential fingerprint where possible.
File.WriteAllLines(textFilePath, customers);
Error : Directory not found exception was unhandled
I am getting a error
Thanks for the tutorial this is what I was looking for. But how can I read write and create files which are saved in individual paths? Example – someone installs the program to the disc D but in code is given dir to desktop on the disc C. Does IO system offers path reading?
I know there is smth like Environment.MachineName and so on, but in this case you have to define a lot of strings to get the whole path.
12:10, 13:00, 17:30 I just love your reactions!
Hi how can we read a file from the middle of the file to the top of the file??
Lol he sounds like Boomhauer when he's fast
why do you use byte to transform the random string?
I like the variety of how you create an instance of a stream.

Thank you for this video
I can not speak and understand english. But dont know why I've understood this SYSTEM IO
File download not webclient
Thank you for your well-made video. I really learned something??
Derek, are you based on your recommended book to make these C# tutorials? Thank you.
I really like the you speak your american english! like someone talking to his own heart
Hello! I need some help. So I am new to C# and currently working on a small project of mine. How do I make a program so when you run it, it will ask you about for example "how many subfolders do you want to create" and you type in the amount of folders that you wish to create and the program will do it. I have been stuck on this problem for quite some time now and can't find any solutions. Does anyone in here know? Basically only folders, no text files or anything like that. Thanks.
Ok tutorial -but it would be more useful if time were explained on why things work one way instead of just showing…
That is clearly NOT a random string
Derek I wish you would make these videos twice as long and really take more time in explaining everything slower. These videos seem so rushed. I really like the videos but I always need to rewind and pause. Also you seem to gloss overthings when really if you explained them in detail I think people would learn better from watching these videos.
Great as always!
Can you make a video about creating a C# RegEx Console app? I want to find and replace things in some html documents.
How can you add more text to the file after sr.Close()?
from which age did you start learn programming?
thanks for the tutorials
A question. What is the @ letter before the strings? I have been googling it for 10 minutes and can't find the answer…
A question, when Reading data with filestreams, Why is it we need to create an additional bytearray to store the bytes from rsByteArray, Why not just get the rsByteArray and use the .GetString function on that?

//Creating a directory
DirectoryInfo newDirectory = new DirectoryInfo(@"C:Usersetcetc");
newDirectory.Create(); //This method will create a directory
newDirectory.Delete(); //This method will delete the directory
Thanks you so much Derek your video are the best
First video I've watched but will definitely watch the others.
By far the most informative and well laid out tutorial I've seen.
Straight to the point and clearly shows how methods can be used.
I have subscribed?
I feel so much better after watching this.
