Linq and IEnumerable - case insensitive?

shn40023-Dec-09 16:31

I have this piece of code that "selects" from an Excel data stream and also from an XML one:
foreach (var ex in dataExcel)
{
ExcelRecs++;
IEnumerable<xelement> part =
from item in Partlists.Descendants("Partx")
where (string)item.Element("Part_name") == ex.Name
select item;

.....
}

How do I make the comparison "case INSENSITIVE"? that is either one of item.Element("Part_name") or ex.Name can be upper case and the other lower case, the == comparise would still be true.

Thanks for your help!

you want to compare two strings in a special way?
what class could possibly help you?
and what would be a nice name for a relevant method in such class?

Use string.Compare.

var part = from item in Partlists.Descendants("Partx")
where string.Compare((string)item.Element("Part_name"), ex.Name, true) == 0
select item;

Problem with List<>

Hi,

I have a problem with VS2010beta2 and .NET Framework Client Profile, although I would expect the problem to be something to do with my inexperienced coding.

I have this block of code..

struct sGamePort
{
    public string sgpProtocol;
    public UInt16 sgpPortStart;
    public UInt16 sgpPortEnd;
}

struct sGamePortItem
{
    public string sgpName;
    public List<sGamePort> sgpPortList;
}

List<sGamePortItem> sGames;


private sGamePort ParsePorts(string[] line)
{
    sGamePort gp = new sGamePort();
    gp.sgpProtocol = line[0];
    int num = line.Count();
    if (num == 2)
    {
        // single port opened...
        gp.sgpPortStart =  Convert.ToUInt16(line[1]);
        gp.sgpPortEnd = Convert.ToUInt16(line[1]);
    }
    if (num == 3)
    {
        // port range opened...
        gp.sgpPortStart = Convert.ToUInt16(line[1]);
        gp.sgpPortEnd = Convert.ToUInt16(line[2]);
    }
    return gp;
}

Where line is a string array which essentially holds some tokens.
ie.
line[0] = "NAME"
line[1] = "JOHN"
line[2] = "YOUNG"

Now, in a seperate function I have

sGamePortItem pi = new sGamePortItem();
pi.sgpProtocol = "TCP";
pi.sgpPortList.Add(ParsePorts(strCMD));

This gives me a Null Reference Exception, so I changed it to this...

sGamePortItem pi = new sGamePortItem();
pi.sgpProtocol = "TCP";
sGamePort test = new sGamePort();
test = ParsePorts(strCMD);
pi.sgpPortList.Add(test); // ERROR HERE

Now, the error only occurs on the specified line above.. What am I doing wrong? Is it to do with me using the new keyword incorrectly? Or do I not use 'new'?

Any help would be appreciated as this has been confusing me for a few hours now, lol

Thanks again.

John

The problem is that your line:

public List<sGamePort> sgpPortList;

should be:

public List<sGamePort> sgpPortList = new List<sGamePort>();

Need to assign a target to sgpPortList before you dereference it, hence the null ref exception.

Damn, I knew it would be something trivial...

Thanks for waking me up to a silly mistake, Big Grin | :-D

EDIT:
Now I'm getting the error "cannot have instance field initializers in structs"...
Hmmm, this could be a pain...

EDIT AGAIN:
I realised what was wrong.. I hadn't been initialising the sGamePortItem in the list..

sGamePortItem pi = new sGamePortItem();
pi.sgpPortList = new List<sGamePort>();  // THIS WAS NEEDED.

Thank you for your help, it made me think more about the initialisation...

You need to initialize the list of the struct "sGamePortItem" before assigning the object.

Hold the parent session when calling a showModalDialog child

Hi,

I am developing a web app in VB.NET 1.1. In some Webforms I call a showModalDialog child, but when I close it, the parent session is removed.

Please, how can I hold it?

Thanks in advance,
Jose Alvarez de Lara

Modal dialogues can't refer to their parent using opener. You need to pass a reference to the parent in the second parameter to showModalDialog.

Hi Puri,

That is what I did. And I maintain a conversation between then parent and the child.
I am thinking if it is possible to send the parent session to the child and bring it back
to the parent when close the child.

Thanks for your interesting,
Jose

Hello,

There are two articles here in the Code Project. I am talking about "Those Crazy Popups" and "ASP.Net Modal Window Server Control". I am looking for something like them, but I need to fix those articles into my issue.

Any help will be appreciate.

Hi,

I have found the answer googling.

It is enough putting

Response.Cache.SetCacheability(HttpCacheability.NoCache)

in the Page_Load of pop up window.

On the other hand here is the code snippet,

Page1.aspx

function DoDo(){
window.showModalDialog("Show.aspx","aa");
}

<asp:linkbutton id="LinkButton1" onclientclick="DoDo()" runat="server">LinkButton
protected void Page_Load(object sender, EventArgs e)
{
Session["AA"] = "have a good day!";
}

Show.aspx

protected void Page_Load(object sender, EventArgs e)
{
if (Session["AA"] != null)
Response.Write(Session["AA"].ToString());
else
Response.Write("NULL..........");
}

I hope this help to other people.

Regards,
Jose

DesignSurface Serialization problems

Hello,

I have folllowing problems on a customized DesignSurface. I Load and save the design in a sort of XAML File (proprietary).

- wenn I copy and Paste a TabControl, Order of TabPages is wrong (reversed). Objects come in the wrong order in the Serialize method of my IDesignerSerializationService implementation.

- Wenn I copy and paste a Context menu, the Paste operation fails for the menuitems. It says "Toolstripmenuitem cant be insert in Container of type Form".

- I Have IExtenderprovider on some controls (ToolStrip). How can I handle that ? wen I Paste, The Design surface searches an object with the same name on the destination surface.

Thanks

ADO Delimiters: Space and Tab

I've been trying to find a webpage containing the syntax of connection strings, especially for Tab, Space, and multiple delimiters. Right now, I am trying to query a text file that is space delimited where I treat consecutive delimiters as one.

The following code snippet is from my connection string in C++ .NET

Extended Properties=\"text;HDR=Yes;FMT=Delimited(' ')\""

Do you know what the syntax should be and where I can find a page with a list of the delimiters with syntax? I have examples for csv format, but have not found other examples on google yet.

Yes, I already have checked connectionstrings.com. They have examples with Tab, semi-colon, and comma. I have not gotten a space delimiter to work however.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
