This may not the most efficient or optimized way to do it, but it’s easier to read if you are not familiar with log maths, and should be fast enough for most scenarios. string[] sizes = { “B”, “KB”, “MB”, “GB”, “TB” }; double len = new FileInfo(filename).Length; int order = 0; while (len >= … Read more
UPDATE: I liked this question so much I made it the subject of my blog on November 18th 2011. Thanks for the great question! I’ve always wondered: what is the purpose of the stack? I assume you mean the evaluation stack of the MSIL language, and not the actual per-thread stack at runtime. Why is … Read more
F8 (and Shift+F8 to go backwards). Or at least that’s what it is in my keyboard profile – you can go to tools\options\environment\keyboard and check out Edit.GoToNextLocation. Note If you configured Visual Studio using VB keyboard settings, no key has been assigned to this function. You need to pick your own and assign them.
Assuming the day of the month is irrelevant (i.e. the diff between 2011.1.1 and 2010.12.31 is 1), with date1 > date2 giving a positive value and date2 > date1 a negative value ((date1.Year – date2.Year) * 12) + date1.Month – date2.Month Or, assuming you want an approximate number of ‘average months’ between the two dates, … Read more
Actually, although I blogged (see Luke’s answer), I think this is better than my IDisposable wrapper. Typical code: Service<IOrderService>.Use(orderService=> { orderService.PlaceOrder(request); }); (edit per comments) Since Use returns void, the easiest way to handle return values is via a captured variable: int newOrderId = 0; // need a value for definite assignment Service<IOrderService>.Use(orderService=> { newOrderId … Read more
In most cases, List<T> is more useful. LinkedList<T> will have less cost when adding/removing items in the middle of the list, whereas List<T> can only cheaply add/remove at the end of the list. LinkedList<T> is only at it’s most efficient if you are accessing sequential data (either forwards or backwards) – random access is relatively … Read more
There is already a foreach statement included in the language that does the job most of the time. I’d hate to see the following: list.ForEach( item => { item.DoSomething(); } ); Instead of: foreach(Item item in list) { item.DoSomething(); } The latter is clearer and easier to read in most situations, although maybe a bit … Read more
Depends upon the version. The If operator in VB.NET 2008 is a ternary operator (as well as a null coalescence operator). This was just introduced, prior to 2008 this was not available. Here’s some more info: Visual Basic If announcement Example: Dim foo as String = If(bar = buz, cat, dog) [EDIT] Prior to 2008 … Read more
This sample shows how to read and write a string to a MemoryStream. Imports System.IO Module Module1 Sub Main() ‘ We don’t need to dispose any of the MemoryStream ‘ because it is a managed object. However, just for ‘ good practice, we’ll close the MemoryStream. Using ms As New MemoryStream Dim sw As New … Read more
