System.IO changing text file

[ThinkingBeyond]

Hi,

I have a program which holds details of members in a text file which i can display and add more members to using Streamwriter and Streamreader.

But I now need to be able admend details in the text file.

I need a way of finding the member using their member number in the text file and then i need to update their performance which is another exsisting line in the text file.

Any ideas please?

Regards,
Ben

Sounds like you should look into using a collection for this. You can read each line into a collection, modify the data as needed then simply write a whole new file when needed.

Jb has it right. Look into object serialization. It's pretty simple to implement. More info in the following article : http://www.devcity.net/Articles/292/4/article.aspx
