Hi there.
I want to serialize some WMI classes that generate with one tools of .net framework called "Mgmtclassgen.exe". I tried a lot but nothing Ive gotten.
In this case I try to add property of my class to datatable and then serialize it to XML. I added. For serialization I try this code:
<pre class="prettyprint prettyprinted <span class="pln <span class="typ DataSet<span class="pln ds <span class="pun =<span class="pln <span class="kwd new<span class="pln <span class="typ DataSet<span class="pun ();<span class="pln
ds<span class="pun .<span class="typ Tables<span class="pun .<span class="typ Add<span class="pun (<span class="pln dt<span class="pun );<span class="pln
<span class="kwd string<span class="pln s <span class="pun =<span class="pln dt<span class="pun .<span class="typ DataSet<span class="pun .<span class="typ GetXml<span class="pun ();[/code]
after that I get error with this message:
System.InvalidOperationException was unhandled by user code<br/>
HResult=-2146233079<br/>
Message=System.Management.ManagementBaseObject cannot be serialized because it does not have a parameterless constructor.<br/>

This is my question:
How can I serialize this class with System.Management.ManagementBaseObject property and System.Management.ManagementSystemProperties property?
