CHAPTER 12 ?– BUILDING A COMPLEX CONTROL 581
The internal implementation is not as important as understanding the types that are
passed into the web service. The Search method takes a SearchRequest object as its sole parameter,
which is configured with the search query string on its Query property. The SearchRequest
object has a Requests property that takes an ArrayList of one or more SourceRequest objects.
Each SourceRequest represents a search query, so it is possible to perform multiple searches in
a single web service method call on MSNSearchPortType.Search. Configuring the SourceRequest
object is the first step in performing a search request. Table 12-1 provides an explanation of the
properties that can be configured on a SourceRequest object.
