It’s very simple using System.Security.Cryptography.MD5: using (var md5 = MD5.Create()) { using (var stream = File.OpenRead(filename)) { return md5.ComputeHash(stream); } } (I believe that actually the MD5 implementation used doesn’t need to be disposed, but I’d probably still do so anyway.) How you compare the results afterwards is up to you; you can convert the … Read more
A method group is the name for a set of methods (that might be just one) – i.e. in theory the ToString method may have multiple overloads (plus any extension methods): ToString(), ToString(string format), etc – hence ToString by itself is a “method group”. It can usually convert a method group to a (typed) delegate … Read more
Based on the first sentence of the question: “I’m trying to write out a Byte[] array representing a complete file to a file.” The path of least resistance would be: File.WriteAllBytes(string path, byte[] bytes) Documented here: System.IO.File.WriteAllBytes – MSDN
The following will work for a DateTime that has fractional milliseconds, and also preserves the Kind property (Local, Utc or Undefined). DateTime dateTime = … anything … dateTime = new DateTime( dateTime.Ticks – (dateTime.Ticks % TimeSpan.TicksPerSecond), dateTime.Kind ); or the equivalent and shorter: dateTime = dateTime.AddTicks( – (dateTime.Ticks % TimeSpan.TicksPerSecond)); This could be generalized into … Read more

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
You can use the static method Enum.GetNames which returns an array representing the names of all the items in the enum. The length property of this array equals the number of items defined in the enum var myEnumMemberCount = Enum.GetNames(typeof(MyEnum)).Length;
There is an overload of Url.Action that takes your desired protocol (e.g. http, https) as an argument – if you specify this, you get a fully qualified URL. Here’s an example that uses the protocol of the current request in an action method: var fullUrl = this.Url.Action(“Edit”, “Posts”, new { id = 5 }, this.Request.Url.Scheme); … Read more
Is there a clearer definition of a “zombie thread” than what I’ve explained here? Seems like a pretty good explanation to me – a thread that has terminated (and can therefore no longer release any resources), but whose resources (e.g. handles) are still around and (potentially) causing problems. Can zombie threads occur on .NET? (Why/Why … Read more
Open web.config file and find the System.Web.Mvc assembly definition: assembly=”System.Web.Mvc, Version=3.0.0.0 …” It’s an MVC3 as you see. Via web you can use MvcDiagnostics which is similar to phpinfo() functionality in PHP.
