🔒 Closed Vb.net filehandling edit/update in console application

[marleybob]

Na coconfused na po ako. I want to replace the value sa txt file gamit ang arraylist then marereplace din yung data na nasa loob ng " txt file " , in short i want to edit the data. (1st) gumamit ako ng reader para ma add yung data sa Arraylist. (2nd) Gumamit ako ng "streamwriter" para ma edit o i overwrite lang yung specific data . kaya naghihingi ako ng input galing kay user kung anung id number ang iiedit niya. na update naman siya but ang problema ay nawala yung ibang data.

ITO original laman ng txt file : ex:
1, James , 200 , 24
2, Michael, 300, 10
AFter ma edit/update : ex:
2, Lebron James, 201, 23

Mas mabuti kung sa stackoverflow ka magpatulong Sir.

For every loop of idList, you create an instance of StreamWriter. StreamWriter, has this default behavior where it creates a file (if it does not exist) or overwrites a file (if it does exist).

Solution:
Using sw as StreamWriter = new StreamWriter(filePath, TRUE)
sw.WriteLine(line);
End Using

I already done it. okay na po salamat oo ganyan po ginawa ko kaso inalis ko yang true para ma overwrite.
