When using select or group, you will sometimes want to generate a temporary result that will be used by a subsequent part of the query to produce the final result This is called a query continuation (or just a continuation for short), and it is accomplished through the use of into with a select or group clause It has the following general form: into name query-body where name is the name of the range variable that iterates over the temporary result and is used by the continuing query, specified by query-body This is why into is called a query continuation when used with select or group it continues the query In essence, a query continuation embodies the concept of building a new query that queries the results of the preceding query

described later in this chapter Here is an example that uses into with group The following program reworks the GroupDemo example shown earlier, which creates a list of websites grouped by top-level domain name In this case, the initial results are queried by a range variable called ws This result is then filtered to remove all groups that have fewer than three elements

// Use into with group using System; using SystemLinq; class IntoDemo { static void Main() { string[] websites = { "hsNameAcom", "hsNameBnet", "hsNameCnet", "hsNameDcom", "hsNameEorg", "hsNameForg", "hsNameGtv", "hsNameHnet", "hsNameItv" };

Part I:

// Create a query that groups websites by top-level domain name, // but select only those groups that have more than two members // Here, ws is the range variable over the set of groups // returned when the first half of the query is executed var webAddrs = from addr in websites where addrLastIndexOf('') != -1 group addr by addrSubstring(addrLastIndexOf('')) into ws where wsCount() > 2 select ws; // Execute the query and display the results ConsoleWriteLine("Top-level domains with more than 2 members\n"); foreach(var sites in webAddrs) { ConsoleWriteLine("Contents of " + sitesKey + " domain:"); foreach(var site in sites) ConsoleWriteLine(" " + site); ConsoleWriteLine(); } } }

What do you think Did you notice the salutation Starting an E-mail with Hi instead of the more traditional Dear signals a less formal tone Using the category salutation team is a good way of indicating a group purpose Go ahead Calculate the Empathy Index, then compare your assessment with the following analysis (References to the team are in boldface and the reference to Jan, the writer, is underlined Note that references to we, and our aren t counted because they include both the team and Jan)

The following output is produced:

Top-level domains with more than 2 members Contents of net domain: hsNameBnet hsNameCnet hsNameHnet

As the output shows, only the net group is returned because it is the only group that has more than two elements In the program, pay special attention to this sequence of clauses in the query:

Now formula II above enables us to calculate the last sum explicitly The result is that R( f, P) = = In sum,

group addr by addrSubstring(addrLastIndexOf('')) into ws where wsCount() > 2 select ws;

First, the results of the group clause are stored (creating a temporary result) and the where clause operates on the stored results At this point, ws will range over each group obtained by group Next, the where clause filters the query so the final result contains only those groups that contain more than two members This determination is made by calling Count( ), which is an extension method that is implemented for all IEnumerable objects It returns the number of elements in a sequence (You ll learn more about extension methods later in this chapter) The resulting sequence of groups is returned by the select clause
