Yes, We can have work around for optional parameter.

See the below code,
if you call

http://<uri>/get - It will call the GetAllertion method
http://<uri>/get/12 - It will call the GetAPerson method with parameter alue 12

So these URL act as optional paramter

C#

//Get Operation
[OperationContract]
[WebGet(UriTemplate = "get" )]
List<person> GetAllPerson();
[OperationContract]
[WebGet(UriTemplate = "get/{id}")]
Person GetAPerson(string id);</person>

Let me know if it is helps to you.

Hi Artha,

The above mentioned method can be used but its not feasible if we have more number of parameters. Suppose say, there are 5 parameters then we need to write 25 functions which is not a good idea. Do you have any alternative for this criteria?

Thanks for the reply.
