If I have a list of filenames in a list, how can I do a case-insensitive lookup?
Dim files As List(Of String) = IO.Directory.GetFiles(myFolder).ToList
If files.Contains(myFileName) Then
'do something
End If
The above snippet will only do a case sensitive search.
I am using the contains method to look through an array to find matches, however I notice that when I use it it is case sensitive. Is there another method I can use to do a case insensitive search or some way to modify the contains method to search case insensitively? [code]
View 3 RepliesI am using this code to get a list of files in a folder:
Dim files() As String = (From file In New IO.DirectoryInfo(myFolder).GetFiles Where file.Extension = ".exe" Select file.Name).ToArray
This works fine, but the problem is that it selects only files with the extension of "exe" & skips files that have an "EXE" extension. Is there any way to make it case-insensitive, to make it return any combination of upper/lower case letters in the extension?
I dislike WPF's inability to interpret text in a case-insensitive way.Are there any tools (i.e. VS plugins) out there that will take my VB .NET code and handle the case-sensitivity issues for me?Edit: Now with examples.

visual basic.net is case insensitive so it allows the coder to write without caring or remembering the casing of variables. it also relieves from the 'undeclared variable' errors if you use the variable in another case than the one used in declaration. The fact that its line termination is a line feed makes it even more readable unlike C# or c++ that need good care in the casing and contineous war with following up with the {}, matching them and figuring out which is for which.
my question is what are the advantages of c# over vb knowing that both get compiled to MSIL so there is almost no performance difference between the two languages?
I have spend a couple of hours trying to figure out why my generic Dictionary(Of String, String) is not ignoring case.Here is my code:

This wouldn't build in a VB project because VB.NET is case insensitive. I tried deleting one set of and/or, but when the XML is created, it simply ignores the selected value. I also tried appending an X at the end of one the sets which also failed. Is there a way to make this work? I also tried updating the XSD so it just had two values without success. The interesting thing to note is that default is set to "and" and while debugging it will set it to and, it doesn't actually produce the node attribute of it just generates.
I have a TextBox that need to be case-insensitive. For example, I have this. If searchTextBox.Text = "Park" Then... I need results back if "Park" is typed or "park".

Is there any way to use Dim Str as String = "UPPERlower"Str.Contains("UpperLower") and have it return true?
View 5 RepliesI've read that it's unwise to use ToUpper and ToLower to perform case-insensitive string comparisons, but I see no alternative when it comes to LINQ-to-SQL. The ignoreCase and CompareOptions arguments of String.Compare are ignored by LINQ-to-SQL (if you're using a case-sensitive database, you get a case-sensitive comparison even if you ask for a case-insensitive comparison). Is ToLower or ToUpper the best option here? Is one better than the other? I thought I read somewhere that ToUpper was better, but I don't know if that applies here. (I'm doing a lot of code reviews and everyone is using ToLower.)

I've been using text.indexof() to see if a string is located inside another string, however is it it possible to do a case sensitive/insensitive search option? I've been looking around Google and not having much luck with it.
A huge bonus would be if it could count the number of occurrences inside the string!

I'm having trouble when trying to do a case-insensitive query on a table. Right now the query is:
txtQuery = "SELECT Status, RankingSearchEngines FROM [tbl-DATA-Client-Keywords] WHERE [Client-ID-Code] = '" & clientNo & "' AND lower(Keyword) LIKE '" & sField(0) & "';"
The actual query executed is:
SELECT Status, RankingSearchEngines FROM [tbl-DATA-Client-Keywords] WHERE [Client-ID-Code] = '1402' AND lower(Keyword) LIKE 'flyer printing';
I have an entry 'Flyer Printing' in the database, and this query works perfectly without the case-insensitive check.I'm not sure if this is an OleDB issue, as I've never had this sort of problem with SQLPlus, or anything else
The exception being thrown is:
IErrorInfo.GetDescription failed with E_FAIL(0x80004005).

I started a forms solution in VB 2008, created a datasource to an access database (2010) and used the datagrid view to display the data. 3 fields in the access database are lookup fields with 2-8 values each, typed in by me, since the linking to other fields did not work. This is not working either. When I change the column to combo-box or not, those values, typed into access, are NOT showing up in the datagrid. the combo box has its drop down arrow but the value fields are empty.

I'm having issues with finding something in list, and removing the item, ignoring the case of characters in string.
The code goes:
Dim listItems As New List(Of String)
Dim pattern As String = "AbC"
Dim array() As String
array = {"ABC", "abc"}
listItems.AddRange(array)
Here I'd like to remove all items from listItems, that are abc, no matter what case single characters of item are, including mixed case items. So in this example, every items should be removed
listItems.Remove(listItems.Find(Function(r) r = pattern))
If I change pattern to match the case of item, then item #2 gets removed:
pattern = "abc"
listItems.Remove(listItems.Find(Function(r) r = pattern))
How can I find item in listItems, ignoring the case characters in pattern?
