I have a WCF Service on a server whose service is also configured as WebInvoke:
[WebInvoke(
Method = "POST",
UriTemplate = "/work",
BodyStyle = WebMessageBodyStyle.WrappedResponse,
ResponseFormat = WebMessageFormat.Json,
RequestFormat = WebMessageFormat.Json)]
Consumption is successful in a PCL project, but depending on the information that is passed, the service will handle and trigger exceptions:
Call to service:
HttpResponseMessage response = await client.PostAsync(uri, content);
The return information is read if response.IsSuccessStatusCode
is not true, I get it as follows:
var result = response.Content.ReadAsStringAsync().Result;
This result is a string of an html document, it contains a lot of information, and the error message I'm looking for is in the body tag, precisely inside a div whose id is equal to "content". how can I get the message only, some specific way?
result:
<?xml version="1.0" encoding="utf-8"?>
