You often (but not always) want to trim whitespace from the beginning and/or end of a piece of text; especially user-provided text. When storing data in a SQL database, for example, it is frequently desirable to trim this whitespace. With that in mind, the framework provides us with the Trim, TrimStart, and TrimEnd methods. Example 10-77 uses Trim to remove the whitespace at the start and end of every line.

foreach (string line in strings) { if (line != null) { string trimmedLine = line.Trim(); if (trimmedLine.Length != 0) { output.AppendLine(trimmedLine); } else { System.Diagnostics.Debug.WriteLine( "Found a blank line (after trimming)"); } } else { System.Diagnostics.Debug.WriteLine("Found a null line"); } }

Notice how we re trimming the line once, and storing a reference to the result in a variable, then using that trimmed string in our subsequent tests. Because we re calling a method on our string instance, we need to test it for nullness before we do that, or we ll get a null reference exception. This means that we don t need to call IsNullOr Empty in our later test. We know that it cannot be null. Instead, we do a quick test for emptiness. It turns out that the most efficient way to do this is not to compare against String.Empty but to check the Length of our string. If we build and run this, we see the following output:

42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83

To be, or not to be--that is the question: Whether 'tis nobler in the mind to suffer, The slings and arrows of outrageous fortune , Or to take arms against a sea of troubles, And by opposing end them.

And in the output window:

Found Found Found Found Found Found Found Found Found a a a a a a a a a blank line null line blank line blank line blank line blank line blank line blank line blank line (after trimming) (after (after (after (after (after (after (after trimming) trimming) trimming) trimming) trimming) trimming) trimming)

You ll notice that Trim has successfully removed all the whitespace at the beginning and end of each line, both spaces and tab characters, but left the whitespace in the middle of the line alone.

us to specify the array of characters we want to trim from the beginning or end of the line. We could use this to get rid of those spurious commas, too, using the code in Example 10-78.

/* Reads the HTTP request from the client and responds with the file the user requested or an HTTP error code. */ public void processRequest(Socket s) throws Exception { /* Used to read data from the client. */ BufferedReader br = new BufferedReader ( new InputStreamReader (s.getInputStream())); /* Used to write data to the client. */ OutputStreamWriter osw = new OutputStreamWriter (s.getOutputStream()); /* Read the HTTP request from the client. */ String request = br.readLine(); String command = null; String pathname = null; /* Parse the HTTP request. */ StringTokenizer st = new StringTokenizer (request, " "); command = st.nextToken(); pathname = st.nextToken(); if (command.equals("GET")) { /* If the request is a GET, try to respond with the file the user is requesting. */ serveFile (osw,pathname); } else { /* If the request is a NOT a GET, return an error saying this server does not implement the requested command. */ osw.write ("HTTP/1.0 501 Not Implemented\n\n"); } /* Close the connection to the client. */ osw.close(); }

string trimmedLine = line.Trim(' ', '\t', ',');

This overload of Trim uses the parameter array syntax, so we can specify the characters we want to trim as a simple parameter list. In this case, we tell it to trim spaces, tabs, and commas. Our output, then, looks like this:

Really Simple Syndication (RSS) is one of the key technologies that have freed customer and vendor data. RSS is a web-feed format used to publish frequently updated content such as blog entries, news headlines, or podcasts. An RSS document, which is called a feed, web feed, or channel, contains either a summary of content from an associated web site or the full text. Users can use RSS readers on the Web or on the desktop to subscribe to the feed to receive any updates. Based on XML and transported on HTTP, RSS has become a standard for publishing text, video, and audio. The name Atom applies to a pair of related standards. The Atom Syndication Format is an XML language used for web feeds, while the Atom Publishing Protocol (APP for short) is a simple HTTP-based protocol for creating and updating Web resources.

To be, or not to be--that is the question: Whether 'tis nobler in the mind to suffer The slings and arrows of outrageous fortune Or to take arms against a sea of troubles And by opposing end them.
