Cann't serialize interface

[Guest]

hello

i have one interface and a class inherit the interface like below:
public interface IFoo
{
string FooName
{
get;
set;
}
}

[Serializable()]
public class Foo:IFoo
{
public string FooName
{
get{ ... }
set{ ... }
}
}

And i have one class using Foo like below:
public class FooContainer
{
public IFoo[] Foos { ... }
}

When i create a web service to delive class FooContainer to client, i get an
error means: Can not serialize interface IFoo.

I want to inherit ISerialzable in IFoo like below:
public interface IFoo:ISerializable.
And implement ISerializable in class Foo, but i get the same error.

What should i do to correct it?

thx.

You can go into the proxy (vb or cs) class generated for the webservice
reference and add the serializable attribute to it. That will make this
work.

It will not work. Fields of interface types are not serializable.
Use this pattern to make them serializable:

[Serializable]
class A {

[NonSerialized]
ISomeInterface Field {
get {
return (ISomeInterface) field;
}
}
private object field;
// or
private ClassImplementingISomeInterface field;

}

[Serializable]
class A {

[NonSerialized]

Correction: the [NonSerialized] attribute is not necessary (and also
invalid in this context).
