LINQ: SELECT WHERE ITEM IN (“A”,”B”, “C”)
Code Snippet if (logs != null && logs.Count() > 0) { List<IQueryable<EventRecord>> list = new List<IQueryable<EventRecord>>(); foreach (string log in logs) { string logName = log; list.Add(eventResults.Where(x => x.LogName == logName)); } int i = 0;

WPF Xaml Conditional Compilation
Silverlight and WPF share a lot of common markup, but Silverlight is a subset of WPF, for maintainability we need to use linked files and conditionally compile items unavailable in Silverlight, this can be done in C# code with #if,

Retrieving an Embedded Resource
Code: Retrieving an Image that is an Embedded Resource (Visual C#) This example retrieves an image that is an embedded resource of the assembly. Example System.Reflection.Assembly thisExe; thisExe = System.Reflection.Assembly.GetExecutingAssembly(); System.IO.Stream file = thisExe.GetManifestResourceStream("AssemblyName.ImageFile.jpg"); this.pictureBox1.Image = Image.FromStream(file); http://msdn.microsoft.com/en-us/library/aa287676(VS.71).aspx

User Defined Table Types Dal
User defined table types can be passed on Ado.Net with the use of DataTables Dal code public static int AddBulkData(Guid itemGuid, List<SettingsPacket> data) { int result = 0; DataTable settingsPacketsTable = new DataTable("dbo.udtTypeName"); /* [Col1] INT, [ColGuid]

Read all bytes from a File
byte[] data = File.ReadAllBytes(file); Why is it not on FileStream, which had previous version of reads? Beats me..

Setting Thread-Level data
Requirement: Store some data that is indpendently accessible within the thread and not shared across the different threads. Solution: [ThreadStatic] public static string MethodName; Notes: If the data is required to be accessible across all threads, we know that the

Test ClassInitialize and ClassCleanup Inheritance
When you have a framework of inherited test classes the following does not work: [TestClass] public class TestBase() { [ClassInitialize] public static void TestBaseClassInitialize(TestContext context) { //never gets called when running inherited test. } [ClassCleanup]

Windows Phone Apps: Xaml Navigation
(It wasn’t easy to search for this since keywords are so context insensitive..) The following command allows us to navigate to different “pages” in the Windows 7 app. NavigationService.Navigate(new Uri("/MapPage.xaml", UriKind.Relative)); The following command navigates to a Xaml page in

^ is for XOR, not power
I just assumed that a ^ 2 = a * a, wrong! it is a XOR a and not applicable to double precision numbers, so I got the following compilation error: Error Operator ‘^’ cannot be applied to operands of
