C# - Case-sensitive Vs Insensitive Languages?
Nov 28, 2010
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'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 just came across an interesting scenario. I have a class in C#:
[Code]...
As C# is case sensitive, this will treat the two variables A and a as distinct. I want to inherit the above class in my VB code, which is not case sensitive. How will the VB code access the two distinct variables A and a?

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]

I 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.
Input:
<Dockpanel DockPanel.Dock="Bottom">
<Label Content="(c) blahblah" HorizontalAlignment="Left" Name="Label2" VerticalAlignment="Bottom" Opacity=".75" Background="White" DockPanel.Dock="bottom"/>
</DockPanel>
Output:
<DockPanel DockPanel.Dock="Bottom">
<Label Content="(c) blahblah" HorizontalAlignment="Left" Name="Label2" VerticalAlignment="Bottom" Opacity=".75" Background="White" DockPanel.Dock="Bottom"/>
</DockPanel>

I created a Web Reference (also tried Service Reference) to a WSDL that had the following node inside an xsd:
<xs:element name="filter">
<xs:complexType>
<xs:choice minOccurs="0" maxOccurs="unbounded">
<xs:element minOccurs="0" maxOccurs="unbounded" ref="condition" />
<xs:element minOccurs="0" maxOccurs="unbounded" ref="filter" />

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 put this at the top of my project:
Option Compare Text
Here is the sub that contains the process name check:
Sub AC3()
Dim ProcessList As System.Diagnostics.Process()
ProcessList = System.Diagnostics.Process.GetProcesses()
Dim Proc As System.Diagnostics.Process
For Each Proc In ProcessList
[Code] .....
No errors, but it only checks the lowercase hack/cheat/inject. I need it to be case insensitive when checking it.
Figured it out and tested and it works. I put, right after dim procname...
procname = procname.ToLower()
works great.

I'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 am working on a program for a client and will need a feature to search for strings from an array without case sensitivity. This currently works, but it is case sensitive. I commented out the code for readability.
' Declare array for goldSmithingExpertise and add items.
Dim goldsmithingExpertise() As String = {"Alluring Earrings", "Alluring Ring", "Alluring Belt", "Howling Staff", "Dawn Ring", _
"Melancholy Earrings", "Melancholy Belt", "Melancholy Ring", "Jubilant Ring", "Jubilant Earrings", _

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 was wondering if there was a way to create a parameter for a method in VB.NET 2005, to select which case(upper, lower) to test for.For Example
Function Afunction1 (ByVal aString As String, ByVal case As ......) As Boolean
End Function
Where case is the paramter for the user to set as upper or lower.

I was debugging one of the applications I work on and came across an interesting issue. For those unfamiliar with VB.NET, variable names are case insensitive. Therefore,
Dim foo As Integer
FOO = 5
System.Console.WriteLine(foO)
[Code]....
Variable names in VB.NET are typically case insensitive. The GetProperty method on Type seems to be case sensitive when it comes to the property name. Is there a way to call this method "VB.NET style" and ignore case? Or am I SOL here and need to apply a C# mentality and worry about casing?

I am searching through files and only want to include files with certain extensions. Right now I have what is below but it would be stupid to do it that way for 3 or more file types and it isn't completely case insensitive.
If ext = ".jpg" Or ext = ".JPG" Then
I want to check for .jpg .gif .png all case insensitive.

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).
