I have one legacy ASMX service which is consumed by many clients (java, .Net, Python etc). I want to upgrade ASMX service to WCF without impacting my clients (means they will not do any change in their code)
Below function works fine in ASMX:
[WebService(Namespace = "http://example.com/Report", Description = "Save")]
public class Report : WebService
{
[WebMethod(Description = "Save")]
public void Save(string name, string[] skills)
{
}
}
It means when client calls Save method and pass name (string) and skills (string[]) parameter then I get it at service end which I further save in database.
In WCF I wrote below interface and class:
[ServiceContract(Namespace = "http://example.com/Report")]
public interface IReport
{
[OperationContract(Action = "http://example.com/Report/Save")]
void Save(string name, string[] skills);
}
public class Report : IReport
{
public void Save(string name, string[] skills)
{
}
}
When I call WCF service from same legacy client then I get name value but not skills value (which is string[]).
Please help how I can get the string[] values. I cannot change client code.
I expect that when I change ASMX to WCF then it should work without impacting my clients. I am unable to get value of skills (which is string array).
It seems in WCF, system is unable to desterilize the string array. I tried with List instead of string[] but also did not work.

I got a solution. I created ArrayOfString class and added CollectionDataContract attribute. Like below
Now if client will call the method like below:
At service end I will get the array values in object of ArrayOfString.
By this I don't need to change my legacy clients who created proxy (ReportClient) using ASMX service.
Try this code:
