Conditional Mandatory fields in wcf data contract

Question

Is their any way we can have conditional Mandatory Data fields in dataContract , for eg - We have IsRequired property as a part of DataMember attribute to make sure particular data field is always passed , is their any way in which we can make data field as conditional mandatory in WCF ?

Answer 1

I don't think there is any such direct support through some property attribute. However you can create a service or endpoint behavior (depending on your requirement) and validate data members/fields as per your validation rules.
