How can I serialize an object with a Dictionary property?

Question

In the example code below, I get this error:

Element TestSerializeDictionary123.Customer.CustomProperties vom Typ System.Collec

Answer 1

In our application we ended up using:

DataContractSerializer xs = new DataContractSerializer(typeof (T));

instead of:

XmlSerializer xs = new XmlSerializer(typeof (T));

which solved the problem as DatacontractSerializer supports Dictionary.

Another solution is ths XML Serializable Generic Dictionary workaround also works in the above example, and there is a long discussion at that link from people using it, might be useful for people working with this issue.
