interface in webservice

Can I use such webservice:

[WebMethod]
public void SetFieldValue(IFieldValue fieldValue, long itemId)
{
    fieldValue.SetValue(itemId);
}

Where IFieldValue is an interface? if so - how can I determine the instance type in the client? if I cannot use this in webservice, should I create 4 different webservices that does the same (I have 4 implements of IFieldValue)?

Update: My problem is that I have a webservice that stores an item. Item has fields and is declared as:

class Item {
    IField[] fields{get;set;}

    more properties and methods
}

The answer is no. If you are able to, try an abstract base class instead of an interface - that should serialize correctly, and may be suitable for your requirements.
