Back To Basics - Thinking Beyond ToString()



About Back To Basics - It's often good to look back and fill any gaps we might be having, in certain aspects of the language or framework we use. I'll be examining and blogging about some well known features of C# and .NET, in Back To Basics series - Probably in a bit more detail.




If you want to convert something to string, you might need to find the converter to do the job correctly.

Here is a neat extension method for all your objects, so that it'll find the appropriate converter if one exists, or otherwise, fall back to ToString() :)

public static class ConverterExtension
    {
        public static string ConvertToString(this object value)
        {
            TypeConverter converter = 
              TypeDescriptor.GetConverter(value.GetType());

            // Can converter convert this type to string?
            if (converter.CanConvertTo(typeof(string)))
            {
                // Convert it
                return converter.ConvertTo(value, 
                        typeof(string)) as string;
            }

            return value.ToString();
        }
    }

Now, try this code, and find out what is the result
Color val = Color.Red;

//Call our extension method
string result1 = val.ConvertToString();

//Try with ToString()
string result2=val.ToString();

See what is in result1 and result2, so that you can make out what I'm talking about. Simple, but useful when you work with scenarios where you want to serialize your object's properties.

Top 7 Coding Standards & Guideline Documents For C#/.NET Developers

Some time back, I collated a list of 7 Must Read, Free EBooks for .NET Developers, and a lot of people found it useful. So, I thought about putting together a list of Coding Standard guidelines/checklists for .NET /C# developers as well.As you may already know, it is easy to come up with a document - the key is in implementing these standards in your organization, through methods like internal trainings, Peer Reviews, Check in policies, Automated code review tools etc. You can have a look at FxCop and/or StyleCop for automating the review process to some extent, and can customize the rules based on your requirements.Anyway, here is a list of some good Coding Standard Documents. They are useful not just from a review perspective - going through these documents can definitely help you and me to iron out few hidden glitches we might have in the programming portion of our brain. So, here we go, the listing is not in any specific order.1 – IDesign C# Coding StandardsIDesign C# coding stand…

Hack Raspberry Pi – How To Build Apps In C#, WinForms and ASP.NET Using Mono In Pi

Recently I was doing a bit of R&D related to finding a viable, low cost platform for client nodes. Obviously, I came across Raspberry Pi, and found the same extremely interesting. Now, the missing piece of the puzzle was how to get going using C# and .NET in the Pi. C# is a great language, and there are a lot of C# developers out there in the wild who are interested in the Pi.In this article, I’ll just document my findings so far, and will explain how develop using C# leveraging Mono in a Raspberry Pi. Also, we’ll see how to write few minimal Windows Forms & ASP.NET applications in the Pie as well.Step 1: What is Raspberry Pi?Raspberry Pi is an ARM/Linux box for just ~ $30. It was introduced with a vision to teach basic computer science in schools. How ever, it got a lot of attention from hackers all around the world, as it is an awesome low cost platform to hack and experiment cool ideas as Pi is almost a full fledged computer.  More About R-Pi From Wikipedia.The Raspberry Pi

5 Awesome Learning Resources For Programmers (To help you and your kids to grow the geek neurons)

Happy New Year, this is my first post in 2012. I’ll be sharing few awesome learning resources I’ve bookmarked, and will be pointing out some specific computer/programming related courses I've found interesting from these resources.Also, thought about saving this blog post for my kids as well - instead of investing in these Child education schemes (though they are too small as of today, 2 years and 60 days respectively ). Anyway, personally my new year resolution is to see as much videos from this course collections (assuming I can find some free time in between my regular job && changing my babies diapers).1 – Khan AcademyAs I mentioned some time back, you and your kids are missing some thing huge if you havn’t heard about Khan Academy.  It is an awesome learning resource, especially if you want to re-visit your basics in Math, Science etc.With a library of over 2,600 videos covering everything from arithmetic to physics, finance, and history and 268 practice exercises, th…
