HttpWebRequest
Besides WebClient, the HttpWebRequest class is another option that
allows web service requests to be made. WebClient offers a simple yet effective API to
invoke and consume web services from Silverlight applications. All calls
made through WebClient are actually
passed through the HttpWebRequest
class under the covers. WebClient is
basically a simplified wrapper on top of HttpWebRequest. You should use the HttpWebRequest class when you require more
granular control over the web service call.
HttpWebRequest exposes
properties that allow customization of the web service call by including
headers through the Headers property
and setting the content type through the ContentType property. Table 7-2 lists some of the
most important members of HttpWebRequest used in invoking web
services.
