	Premature .NET garbage collection, or "Dude, where's my FooBar?" [Tip/Trick] 29 Aug 2011 Updated: 29 Aug 2011 Rating: 0.00/5 Votes: 0 Popularity: 0.00 Licence: CPOL Views: 8,340 Bookmarked: 0 Downloaded: 0 Please Sign up or sign in to vote. It would be very nice if one could ask the .NET compilers to automatically add GC.KeepAlive(this) to the end of a class' methods; IMHO, that should have been a default behavior for classes that override Finalize. Unfortunately, since that isn't possible, one should probably, as a matter of...

C#	Can the C# ‘var’ keyword be misused? [Tip/Trick] 10 Jun 2011 Updated: 10 Jun 2011 Rating: 5.00/5 Votes: 2 Popularity: 1.51 Licence: CPOL Views: 8,382 Bookmarked: 1 Downloaded: 0 Please Sign up or sign in to vote. If the right-hand operand of an assignment is a "new", there's no need to explicitly specify the type of the new variable being created unless the new variable will have to hold items of a more general type than the right-hand operand would indicate. I would consider the code clearer without the...
	Boxing a value type in .NET to make it a reference type [Tip/Trick] 30 Sep 2011 Updated: 2 Oct 2011 Rating: 0.00/5 Votes: 0 Popularity: 0.00 Licence: CPOL Views: 6,390 Bookmarked: 0 Downloaded: 0 Please Sign up or sign in to vote. Mutable structures and classes behave differently when it comes to Generics. Although such differences cause some people to deride mutable structs as evil, they simply offer different semantics from class types. Such semantics are for many purposes superior to those of class types, but some code...
	Use wildcard characters * and ? to compare strings [Tip/Trick] 6 May 2010 Updated: 6 May 2010 Rating: 4.00/5 Votes: 1 Popularity: 0.00 Licence: CPOL Views: 6,620 Bookmarked: 0 Downloaded: 0 Please Sign up or sign in to vote. Using the Substring operation repeatedly as you do is apt to be very slow. Better would be to pass the starting indices and lengths of the two strings as parameters. That would require a manual loop to replace the String.Trim function, but it would avoid the need to create lots of new string...
C# 4.0	Try - finally alternative [Tip/Trick] 5 Jun 2011 Updated: 5 Jun 2011 Rating: 0.00/5 Votes: 0 Popularity: 0.00 Licence: CPOL Views: 5,560 Bookmarked: 1 Downloaded: 0 Please Sign up or sign in to vote. There are times when "try"-related wrappers can be useful. For example, a Try() wrapper DLL written in a language other than C# could pass an Exception parameter to the Finally clause indicating whether the Try clause succeeded. For example:Try (() => {DoSomething();}, (Exception inner_ex)...
	Generic Thread Start [Tip/Trick] 22 Mar 2011 Updated: 22 Mar 2011 Rating: 0.00/5 Votes: 0 Popularity: 0.00 Licence: CPOL Views: 5,050 Bookmarked: 0 Downloaded: 0 Please Sign up or sign in to vote. Another approach is to use a generic delegate-factory class. Essentially, the class has a field of generic type, a delegate field which accepts an argument of that type, an parameterless instance method which accepts an argument of that type and invokes the delegate with it, and a static method...
