.net - Convert StringCollection To List<String>
May 10, 2009Normally, I'd choose List<String> [or, in VB, List(Of String)] over StringCollection whenever possible: see also Best string container.
However, as it seems, generics — and hence, List<String> — are apparently not supported in VS 2008's settings designer. Therefore, if I want to use a list of strings in my user settings, I have to resort to using a StringCollection there.
Now as I don't want to see StringCollection throughout my code, I need to convert it to List<String>. How do I do this efficiently? Or, even better, am I mistaken and there is a way to use List<String> in settings designer?

View 3 RepliesSQL Server Open File From Image Field?
Apr 25, 2012I have a field in a SQL Server 2005 DB of type 'image' that contains documents, mostly pdfs. When I view the field in the database, it looks as though the data is stored as a hex string. I have extensively googled and came up with the VB.net function below to convert the field to an actual file, but it only outputs a file containing the string of hex characters rather than the file that the field is supposed to represent.
This is a sample of the fields' data (I have truncated it for privacy purposes):

Create A StringCollection Setting And Manually Enter Some Data?
Jan 16, 2008I have used My.Settings for quite some time now, in both VS2005 and now in 2008, but never noticed this behaviour yet... I must be forgetting something trivial? I create a StringCollection setting and manually enter some data (strings).I write some code to handle this, and I get it to work.
Then, I manually add some new strings (and edit the older ones) in the Settings page, save the project, and run my code again.For some reason, the last changes have not been saved... Whenever I look in the settings page, I see them there, but my code cannot recognize them..

Find A Substring In An ArrayList, StringCollection Or List(Of String)
Jun 7, 2010I've got some code that creates a list of AD groups that the user is a member of, with the intention of saying 'if user is a member of GroupX then allow admin access, if not allow basic access'.
I was using a StringCollection to store this list of Groups, and intended to use the Contains method to test for membership of my admin group, but the problem is that this method only compares the full string - but my AD groups values are formatted as cn=GroupX, etc....
I want to be easily able to determine if a particular substring (i.e. 'GroupX') appears in the list of groups. I could always iterate through the groups check each for a substring representing my AD group name, but I'm more interested in finding out if there is a 'better' way.
Clearly there are a number of repositories for the list of Groups, and it appears that Generics (List(Of String)) are more commonly preferred (which I may well implement anyway) but there is no in-built means of checking for a substring using this method either.
I've settled on using a List(Of), and I've borrowed from Dan's code to iterate through the list.

String.ToCharArray() Stored In StringCollection Conversion To Numbers And Back
Aug 25, 2009I have a string which was converted to a char array and stored in a stringcollection, how do I return the numerical value for the character in each string? How can I reverse this process, getting the character from the numerical value?
I know I could code a Select Case statement, but that would take a very long time as I need to cover every character a person could want to conceivably use in the English language, including punctuation. Is there already a method built into vb.net for doing this?
