Hi,
I am using webservice.I am overcoming an error in the webservice and the error is "Cannot serialize member System.ComponentModel.Component.Site of type System.ComponentModel.ISite because it is an interface" .Can anyone tell me why this error comes?

Hi Sathish....

I'm also having that same problem....

But I'm using IDictionary as a type.

Could anybody pls help...

Hi,
Are you returning something from the webservice?

Yes Sathish!

I found the solution for my problem at here.....please go to last Q & A.

The XmlSerializer errors when serializing an object with a public property of type IList<T>. Since IList<T> is an ICollection, this should work.

Also, it similarly errors when using properties that are of any interface type that inherits from IList<T>. Making that interface explicitly implement IEnumerable doesn't work either (even though the documentation implies that this should work).

Hi there,

Natasha Jethanandani Xml Messaging team from microsoft gave a comment about this...

She says .....

The issue occurs since IList<T> does not implement ICollection and the XmlSerializer does not support interface members other than ICollection and IXmlSerializable.

Microsoft fixing this in a future release.

A work-around for this issue would be to use the fully typed list type as a member type instead of interface.

Hey,
I have found the solution.The issue is when we return something from the webservice,we must specify proper annotation for each and every properties described inside the serializable class.

For example,
[XmlAttribute] when it is a basic datatypes such as string or integer etc,

[XmlArray(property name),XmlArrayitem(arrayType)] for array

Or else,we will get this error anyway ..
