How to write data to an embedded resource

[Jani Mantytorma]

I have embedded resource called Settings.xml. I'm able to read the resource but how can I write data to the resource. The code for read operation follows:

private XmlDocument m_doc = new XmlDocument();

System.Reflecti on.Assembly a = System.Reflecti on.Assembly.Get ExecutingAssemb ly();
System.IO.Strea m stream = a.GetManifestRe sourceStream(th is.GetType(),"S ettings.xml");
if(!(null==stre am))
{
System.IO.Strea mReader rdr = new StreamReader(st ream);
m_doc.Load(rdr) ;
stream.Close();
rdr.Close();
}

Now, if I make changes to m_doc and want to save them to embedded resource, I try like this:

System.Reflecti on.Assembly a = System.Reflecti on.Assembly.Get ExecutingAssemb ly();
Stream stream = a.GetManifestRe sourceStream(th is.GetType(),"S ettings.xml");
m_doc.Save(stre am);
stream.Close();

This raises exception, however: "Stream is not writable." What am I doing wrong?

AFAIK, embedded resources are read-only and cannot be written to.

Re: How to write data to an embedded resource

Thanks for your reply. I slept over night and thought that this could be a
reason. And now you confirmed that.

Now I'm wondering why this (read-only) is not emphasized in the MSDN and in
tutorials. But, indirectly they say it: there are no examples of writing to
an embedded resource.

Embedding a resource file would have been very handy if writing had been
allowed.
