Question

Silverlight 2 - Convert Decimal value to hex value

Asked by: josephdaviskcrm

Using regular .net it is easy to convert an integer decimal value to a hex string value by simply using...

intDecimalValue.ToString("X");

However, I'm finding that many common functions in .net are not available in Silverlight 2.

Does anybody know of any other way that this can be done?

Try converting the decimal to an integer first.  like this:
 ((int)intDecimalValue).ToString("X")


 

by: josephdaviskcrmPosted on 2009-09-25 at 09:47:13ID: 25424691

No I'm sorry.  The variable is already an int.  I just gave it an example name of intDecimalValue.  Note the int at the beginning of the variable name.  I meant for that to signify that it is an int variable.

I actually went ahead and created a method that will convert an integer from 0-255 to a two digit hex number, but that is a very clunky solution.  So if anyone has any better ideas I'm still listening.

josephdaviskcrm, you didnt understand. MogalManic gave you a solution. Example

string hexNumber = intDecimalValue.ToString("X");

Ah, sorry, I just saw that you already tried it, but its not available in silverlight. I havent used silverlight, but cant you create some service that will be used for this purpose?

 

by: MogalManicPosted on 2009-09-25 at 12:23:24ID: 25426344

What exactly is happening?

 Is it throwing an exception or is it just not returning the correct value?

 
Like Priest04 I don't have vs2008 or silverlight so I cannot create a silverlight sample, but don't you have the whole .net environment available to you?

 

by: Priest04Posted on 2009-09-25 at 12:40:38ID: 25426529

I have just created one small example with silvelight, and I dont see the problem. It has a code behind file, which can be used for this purpose:

// code behind xaml file
 
<Grid x:Name="LayoutRoot">
    <StackPanel Orientation="Vertical">
        <TextBox x:Name="myTextBox" FontSize="10" />
        <TextBox x:Name="myTextBox2" FontSize="10" />
        <Button Content="Click Me" FontSize="10" Click="Button_Click" />
    </StackPanel>
</Grid>
 
// code behind xaml.cs file
private void Button_Click(object sender, RoutedEventArgs e)
{
    int a;
    int.TryParse(myTextBox.Text, out a);
    myTextBox2.Text = a.ToString("X");
}

I'm using Silverlight 2 and it does not have access to the entire .net framework.  When I use the .ToString("X") method it does throw me an error.
