    <p>This is similar to a question asked here: <a href="https://stackoverflow.com/questions/10311582/httpwebrequest-get-error-content">httpWebRequest - get error content</a> but I'm hoping to provide some more information in hope of an answer.</p> <p>I am integrating with the LinkedIn API using C#. When I make an <strong>invalid</strong> call to the API, it can return a HTTP response like such (from Fiddler):</p> <pre><code>HTTP/1.1 404 Not Found Server: Apache-Coyote/1.1 x-li-request-id: VL2EER2ROJ Date: Tue, 16 Oct 2012 08:52:59 GMT Vary: * x-li-format: xml Content-Type: text/xml;charset=UTF-8 Content-Length: 266 &lt;?xml version="1.0" encoding="UTF-8" standalone="yes"?&gt; &lt;error&gt; &lt;status&gt;404&lt;/status&gt; &lt;timestamp&gt;1350377580000&lt;/timestamp&gt; &lt;request-id&gt;VL2EER2ROJ&lt;/request-id&gt; &lt;error-code&gt;0&lt;/error-code&gt; &lt;message&gt;Could not find member {/people/XXXXXX}&lt;/message&gt; &lt;/error&gt; </code></pre> <p>I would specifically like to get at the error xml, however HttpWebRequest seems to simply throw the exception and then has nothing to do with the content. In my debugger, I can see that the content length is 266, but any attempt to call <code>(System.Net.WebException).Response.GetResponseStream()</code> results in a <code>stream was not readable</code> exception.</p> <p>This method of returning error messages within a non 200 HTTP status response seems quite popular in web APIs - I'm hoping there is a way to get at these responses...</p>

CO[Read the manual](http://msdn.microsoft.com/en-us/library/system.net.httpwebrequest.getresponse.aspx): _"**Note**: If a WebException is thrown, use the Response and Status properties **of the exception** to determine the response from the server."_ See also [this duplicate](http://stackoverflow.com/questions/11828843/c-sharp-webexception-how-to-get-whole-response-with-a-body).

    2. COWhat version of .NEt is this? This sounds like a bug. Get a system.net trace log and use that to create a bug report on msdn community site. BTW can you show your code? Maybe there is something there that can be changed to make this work?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
