    However, the best solution is to make use of the highest level tools we have available that will do this job, and simply do:


    Excellently put. A mark of a well experienced programmer is efficiently using the language's/framework's tools to be both expressive and concise.

    Anyone can read your method from top to bottom and know what it does, even a very inexperienced programmer. They may not know what File is or that .Take is an extension method, but they could reasonably guess that it "Reads Lines from a File and Takes so many lines to read".

    And @AToastedBiscuit, don't worry that you may not have known about these constructs, as others have said. This comes from working with the tools, learning what they have to offer, and refining your style over time. It's more efficient to use the tools that others have provided you with than write the tool from scratch, so as you find more and more built-in tools, you get more and more efficient with writing code.

    [quote]I would be interested to see an example using yield though
    @andrewsw, here's how I would re-write the example with a yield keyword:

            static IEnumerable<string> ReadLines(string filePath, int linesToRead)
                if (filePath == null)
                    throw new ArgumentNullException("filePath");
                if (linesToRead < 0)
                    throw new ArgumentOutOfRangeException("linesToRead", "Must be zero or greater");
                using (StreamReader reader = new StreamReader(filePath))
                    for (int i = 0; i < linesToRead; i++)
                        string line = reader.ReadLine();
                        if (line == null) { yield break; }
                        yield return line;

    Alternatively, I wouldn't bother giving it a linesToRead parameter, because we can use .Take on the call instead.

            static IEnumerable<string> ReadLines(string filePath)
                if (filePath == null)
                    throw new ArgumentNullException("filePath");
                using (StreamReader reader = new StreamReader(filePath))
                        string line = reader.ReadLine();
                        if (line == null) { yield break; }
                        yield return line;
  2. In Topic: Save a excel

    Posted 17 Jul 2014

    Noorul_A, something important to learn is to not try to do everything on one line. It makes it harder to read, and harder to debug.

    Break it out to another line:
    string path = Output_path + "CRM Opp -" + BU_Name + "-" + output;

    Then, try to put it together on paper the same way the computer would. You know what the values of each of these variables is. Output_path = "D:\new folder". Let's pretend that BU_Name = "some business unit" and output = "someoutput".

    If you just add those strings together, you get this:

    "D:\newfolderCRM Opp -some business unit-someoutput"

    The code is only mashing together strings. If you want to include another string in there, just add it.

    string path = Output_path + "\\" + "CRM Opp -" + BU_Name + "-" + output;

    Note, you have to use "\\" because the backslash character is C#'s "escape character". It allows you to represent unprintable characters with text. To represent a backslash itself, you use two.

    However, Skydiver showed a much better method to use: Path.Combine. It's designed to put parts of folder and file paths together as one.

    Also, I'd like to point out that the pattern may not look like you think it looks. Notice how there's a space before the first dash, but not after the last, etc...

    You should also learn how to use string.Format. It will make composing strings much, much easier.

    string path = string.Format("{0}\\CRM Opp - {1} - {2}", Output_path, BU_Name, output);

    Each "{0}" is a placeholder. They're ordered from 0 up. The parameters after the string get "stuck in" where they belong. It's basically a way to make a "template string" and fill in the template.

    To others: please try to keep replies focused on helping the OP. Don't just throw in links you think might happen to have some information possibly related to the question. It clutters the thread and confuses those looking for help. Participation is awesome, just please keep it relevant and actionable.
  3. In Topic: Method issue in code

    Posted 17 Jul 2014

    I'm a fan of _field. It makes sure you don't accidentally use a field instead of a property, and you can get a quick list of your fields in IntelliSense by typing an underscore. And since I only use that for fields, I don't need to identify them as members vs. local, since only members will ever have an underscore, and locals won't.
  4. In Topic: Funny Customer Stories

    Posted 16 Jul 2014

    Well, if we're telling funny name stories, just a few days ago at work someone discovered a local grocery delivery service was doing a promo, they'd deliver a pint of ice cream with no delivery fee. Silly promo, but someone signs up for it. They get the email that their delivery driver today will be "Dickson Berry". We all had a moment of "were his parents never children?" moment. Kids are brutal and I can't imagine he had an easy time of it.
  5. In Topic: Should I buy the older Visual Studio

    Posted 16 Jul 2014

    That's a good point too; I assumed that he needed the features missing from the Express versions.

    But in that case, why not just use the free version until you get a paying gig that you need to have a license for? Why spend the money now when you might go a different direction later?
