.net - Case Insensitive String Compare In LINQ-to-SQL
May 8, 2009I'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.)

Case Sensitive/insensitive Search Text In A String?
Sep 8, 2010I'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!
Case Insensitive Contains Method
Oct 29, 2009I 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 RepliesGet Filenames Case Insensitive?
Sep 9, 2011I 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?
How To Make WPF Case-insensitive
Jul 21, 2010I 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>
C# - Case-sensitive Vs Insensitive Languages?
Nov 28, 2010visual 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?

Case Insensitive Web Reference Enumeration
Apr 15, 2012I 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:element minOccurs="0" maxOccurs="unbounded" ref="condition" />

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.

Process Name Check Needs To Be Case Insensitive
Oct 25, 2009I 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.

VS 2008 Unable To Do A Case-insensitive Query On A Table?
Jul 13, 2009I'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).

Change Case Of Specified Characters In A String?
Sep 27, 2011I have all-one-case strings representing postal addresses stored in a database, but I want to capitalize US state abbreviations (e.g. " ca " to " CA ") when the abbreviation is separated from the rest of the string by a space on either side.The lousy way I could do it would be to have 50 statements like
If addressString.Contains(" al ") Then addressString.Replace(" al ", " AL ")
If addressString.Contains(" ak ") Then addressString.Replace(" ak ", " AK ")
...
Edit: That is a really lousy way! Here's what I did instead:
addressString = StrConv(addressString, VbStrConv.ProperCase)
'This needed to be done anyway, but it turns " ak " into " Ak ".

Generic Function With Special Case For String

End Function
In the special case where the field value is null and T is String, I want to return String.Empty instead of Nothing.
