  • Decimal data type for financial applications

    My current project uses a double data type for its values and i have raised a suggestion to convert it to decimal data type instead. I remember that it is recommended to use decimal over double for financial applications because decimal data types have...

  • Use standard format characters in string formatting

    Whenever you want to format a currency, date, etc. for your application, try to avoid hardcoding your custom format's in your BoundColumn's DataFormatString, ToString format parameter, etc. More often that not, you'd want those formats to be the same...

  • All about @

    The @ (at) sign in .NET is used for verbatim strings. When you're tired of dealing with escape characters particularly for filenames, you make use of it: [code language="C#"] string filename = @"C:\joeycalisay\projects\" as compared to string filename...

  • Default modifier in .NET

    Obviously you already know that private is the default modifier in .NET. When you declare a field inside a class this way: [code language="C#"] public class Jokiz { int age; } [/code] the age field is private to the Jokiz class by default. Do you know...

  • StringBuilder.AppendFormat

    I was refactoring some of our codes yesterday when I bumped into a class used for reporting which is string concat intensive. Obviously, we should use the StringBuilder class due to " strings are immutable " (kind of cliche these days which should be...

  • C# Programmer's Cookbook

    Last thursday, I attended Stanley Tan's session at Microsoft. I didn't expect him to repeat his demos and stuff last january techfest @ shangri-la. However, it was worth it because I have won an MSPress book (first time I won in a raffle). C# Programmer...

  • IS and AS operator

    Boxing and unboxing in C# has a performance cost and the use of the IS and AS operator in casting objects is trivial for me. I thought before that: [code language="C#"] if (boxed is Person) { Person unboxed = boxed as Person; //do something } [/code]...

  • The (-) operator

    I used to multiply a numeric number to -1 just to get its additive inverse (negative value for positive numbers) and I found out that the (-) operator does it implicitly. int value = 10 int negativeValue = value * -1 int negativeValueAlso = -value

  • Passing and Returning Reference Types

    I’ve read this excellent article on Arrays of Jeffrey Richter from Wintellect at MSDN here and there are a number of good points in coding, the one I love most is the section on Passing and Returning Arrays . If you always design your methods so that...

  • Efficient For Loop

    [code language="C#"] for (int i = 0; i < collection.Count; i++) { //do something with collection } [/code] I’ve done this before and for me, the efficient way is to store the Count property of the collection rather than access it everytime for the...

  • Assignment in a WHILE condition

    Before, I used to think that in C, the assignment operator always evaluate to true. It is because of this context: [code language="C#"] while (intLeft == intRight) { //do whatever } [/code] If you mistyped the comparison operator (==) as a single equal...
