I'm using text files as an array to store and remove information, however I do not know know how to adapt this code so the line I search for is removed.
My text files are set up as such:
021,Donovan,56 Eynesford Crescent,Bexleyheath,CT5 1TR,09/08/1967,13 March 2012,Bronze
062,Fredrikson,6 Freil Road,Gravesend,CT9 1RB,12/06/1995,13 March 2012,Silver
So I can search and locate the ID, in these cases 021 or 062, but I want to be able to remove the line I want, once it's been found.

Im having a little trouble with this Visual basic project I have to do. I need to create an airline reserve system in which the user selects whether they want first class or economy using a radio button. Also once the user hits reserve seat the first seat number should turn from green to red in the section they selected. If the user was then to hit reserve seat again the next seat (seat 2) would turn from green to red and so on. I know I have to use a control array. This is how far I have gotten.

1) search the array to find duplicates and add them to a second array, then have a second pass to remove anything which matches the second array.
2) search the array for one duplicate and store it, then search the array again to remove the duplicates, and run that process until there are no more duplicates.
Then again, I could be going about this completely the wrong way. If that's the case, feel free to knock some sense into me.

I have a semicolon delimited string (e.g. an EMail Address List returned from a database or a textbox). How do I separate the string into an array, sort, and remove duplicates? The code below works to separate the string and sort the results, but doesn't remove the duplicates. I could probably then loop through the array and copy to a new array to eliminate the duplicates, but there must be a better way to do this using the VB.Net Array, String, and Collections handling classes.
