为WCF服务使用IP地址

Question

I have a C# app that calls my WCF on my server.

At some time I will want to move part of my uploading process from client to server to a different server.

So, this is what I was going to do.

My desktop application invokes a WCF hosted on my server using the full DNS name ~ www.mysite.com.

That [web method] will then return an IP address to the client.

The client will then upload images to a DIFFERENT server that is accessible only by an IP address.

The idea is that if my app is successful and I would need to 'load-balance' the image uploads I would then have a mechanism to specify different destination servers to my clients.

So, I started looking in StackOverFlow for a way to dynamically set the IP address/End-Point of my WCF. This was easy to do for web services but it seems to me a bit more difficult for WCF.

Needless to say I was about to go through the answers here but came across a comment saying that the WCF needs to be using DNS.

Is this true?

As this is the only server I got and it is using DNS (I have not got access to a secondary server yet) I cannot test this out.

Are both things possible?

Answer 1

When you write a web service client, you can change the server endpoint programmatically. It has nothing to do with using WCF or not in the server.

MyClient client = new MyService.MyClient();
client.Endpoint.Address = new EndpointAddress(new Uri("target URL"));
client.Open();

You could find more details on the EndPointAddress MSDN reference .

Hope I helped!

Answer 2

MyClient client = new MyService.MyClient();
client.Endpoint.Address = new EndpointAddress(new Uri("target URL"));
client.Open();

It works, we could also use

myService.MyClient client = new myService.MyClient ();
 //enter code here, when the service is created as wcf application
