Collection Xml Serialization

[Doug Holland]

Hey all

I've developed a couple of strongly-typed collections and marked them as
[Serializable], however when I attempt to serialize instances of the
collection I recieve the following exception:

"You must implement the Add(System.Object) method on
PrecisionObjects.Collections.Specialized.StringDic tionaryEx because it
inherits from IEnumerable."

Short of implementing the IXmlSerializable interface, which is intended for
internal use of the .NET Framework, is there a way I can get Xml
Serialization to work?

Implementing the Add(System.Object) method as below:

public void Add(object value)
{
if(value is DictionaryEntry)
{
DictionaryEntry entry = (DictionaryEntry) value;

if(entry.Key is string && entry.Value is string)
{
this.Add(entry.Key as string, entry.Value as string);
}
}
}

Still produced the same exception...

Thanks in advance
