C# Tutorial: Read/Write File [Open/Save File]

when i try to save on the same file i opened it crashes and it says : 'The process cannot access the file 'C:Usersuser1DesktopAtest.txt' because it is being used by another process.'
how do i close the process?

Amazing. Very good explanation without talking in a small video. This is what we want. No more lengthy tutorials. Just quick ones.

Thanks. It actually worked. I forgot to add the filter. So it was confusing but i added it after.
Here:
Text Files(*.txt)|*.txt|Lua Files(*.lua)|*.lua|All Files(*.*)|*.*

your saving does not include saving it as .txt file. we have to add that in ourselves. but how to add it into the code.

this is to read and show text But how can i read a .resx file and save it in another .resx file. I tried adding a resourse1.resx to my project and using resource1.resx=  Resource1.resx = File.ReadAllText(ofd.FileName). But it shows error "project.resource1' does not contain defination for resx.

Good JOB !!!

Thanks a lot man, great tutorials!

Just one question, how could i add for user to choose file types in save option?

Wow this great. Just got one Question though. I play a role playing game and I am making a combat simulator. I have many text boxes I want saved for like character stats and a like. use this method would require me to have a whole text file for each text box. Is there a way I could save and load a group of text boxes to one text file?

@BytesRock it is only windows form application , not web application.

great. Straight to the point on how to do something!
