XML Serialization

[Sjaakie]

Hi,
I've read some articles on serialization, but I don't see how to
serialize the xml-structure below (if it is possible at all). Could you
point me in the right direction?

TIA

<?xml version="1.0" encoding="utf-8" ?>
<Settings>
<ApplicationTitle>...</ApplicationTitle>
<DebugEmail>...</DebugEmail>
<Proxy>
<Enabled>...</Enabled>
<Url>...</Url>
<Port>...</Port>
<Login>...</Login>
<Password>...</Password>
</Proxy>
<Feeds>
<Feed>
<Description>...</Description>
<Url>...</Url>
<DateTimeCorrection>...</DateTimeCorrection>
<RefreshInterval>...</RefreshInterval>
</Feed>
<Feed>
<Description>...</Description>
<Url>...</Url>
<DateTimeCorrection>...</DateTimeCorrection>
<RefreshInterval>...</RefreshInterval>
</Feed>
</Feeds>

</Settings>

use the xsd utility to generate a schema for this xml file. Use this schema
with the xsd utility to generate the class file.

1) xsd myFile.xml
2)xsd myFile.xsd /c

Use the generated Class in your project to Serialize the xml.

Hope this helps.

Cheers!

I've read some articles on serialization, but I don't see how to serialize
the xml-structure below [...]

Just curious: what's the point of serializing XML?
Isn't XML already serial?
Why would you want to drown a dead fish?

You're right, I meant DEserializing

Tantr,
I used the xsd util as described. But somehow I cannot use the output to
deserialize the file. The VS2005 debugger throws the following message:

error CS0030: cannot convert type SettingsFeedsFeed[] to
SettingsFeedsFeed

I use this code to deserialize the file:


FileStream fs = new FileStream(@"Data\Settings.xml", FileMode.Open);
XmlSerializer serializer = new XmlSerializer(typeof(Settings));
settings = (Settings)serializer.Deserialize(fs);


Below are snippets of the generated cs file and the complete xsd.
Can you help me out?
