Serialize GenericWebPart

Hej e.

Er her en som kan vise min hvordan man kan Serialize System.Web.UI.WebControls.WebParts.GenericWebPart.

Her er den kode del jeg vil benytte den i:

var WebParts = new List<TemplateWebPart>();
foreach(WebPart wp in WebPartZoneBase.WebParts)
{                       
var x = new XmlSerializer(wp.GetType());
                       
var _webpart = new TemplateWebPart();
_webpart.WebpartID = wp.ID;
_webpart.WebpartType = webpart.GetType();
_webpart.WebpartPropertys = x.ToString();

WebParts.Add(_webpart);
}

Men denne fejler:
var x = new XmlSerializer(wp.GetType());

og her er fejlen:
System.Web.UI.WebControls.WebParts.GenericWebPart cannot be serialized because it does not have a parameterless constructor.
