hi, I am coming from .php to .net and this is my first foray into the language, so please be gentle!

i am trying to convert this simple multiDimensional array from php to asp.net.

$colors = array( "Titanium Silver"=>'999999', "Deep Green"=>'003300', "Mint Green"=>'52a552', "Black Sapphire"=>'000000', "Electric Red"=>'990000', "Alpine White"=>'eae8da', "Mystic Blue"=>'070446',"Powder Blue"=>'659eec', "Ruby Red"=>'6b0a0a', "Dark Silver"=>'545454' );
foreach ($colors as $key => $value) {
echo "<div class=\"swatch\"><a class=\"swatchcolor\" onclick=\"javascript:paintVehicle('$value')\" style=\"background-color:#$value\" href=\"#\">&nbsp;</a>$key</div>";
}

the desired output is something like this.....

<div class="swatch"><a class="swatchcolor" onclick="javascript:paintVehicle('999999')" style="background-color: #999999;" href="#">&nbsp;</a>Titanium Silver</div>

totally confused as to where to begin here.

Thanks in advance for any direction!

Hello pixelEngine,

Use Hashtable, the Hashtable object contains items (key and value). The keys are used as indexes.


<%@ Page Language="VB" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<script runat="server">

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)

Dim ht As New Hashtable()
ht.Add("Titanium Silver", "999999")
ht.Add("Deep Green", "003300")
ht.Add("Mint Green", "52a552")

Dim result As String = String.Empty
Dim item As DictionaryEntry
For Each item In ht
result += "<div class=""swatch""><a class=""swatchcolor"" onclick=""paintVehicle('" & item.Value & "')"" style=""background-color: #" & item.Value & ";"" href=""#"">&nbsp;</a>" & item.Key & "</div>"
Next

cont.Text = result

End Sub

</script>

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>Hashtable Sample</title>

<body>
<form id="form1" runat="server">
<asp:Literal ID="cont" runat="server" EnableViewState="false"></asp:Literal>
</form>
</body>

ok awesome and thanks otaku149!

NOW I need to figure out a way to take create a function that i can pass a hex color, like ff3300 and have it return a color that is similar, but darker.

I know that this can be done in .php, however I an a .net newb and not sure how to do this.

I imagine it is just splitting up the string into 3 portions and then applying some math to one of the strings?

Thanks for any help!!!!
