A quick look at the LINQ Architecture

-
LINQ is a new feature in Visual Studio 2008, extending the capabilities of C# and VB. We can use Language Integrated Query in querying collections, objects, xml and entities.

For as long as an object derives from IEnumerable it can be queried using LINQ,
LINQ can be used in the following ways.
  • LINQ to SQL
  • LINQ to XML
  • LINQ to Object
  • LINQ to Entities
What does LINQ do? In LINQ to SQL it converts objects queries to SQL Command and when it receives the resultset from the database it then converts it back to objects. Below is an illustration of the LINQ Architecture.

Serializing JSON string to ExpandoObject

-
In some case you want to create and Object from JSON, a great way of doing this to deserialize this JSON to an ExpandoObject. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 /// <summary> /// Convert Json String to an Expando Object /// </summary> /// <param name="that">Json string to convert</param> /// <returns>Expando Object</returns> public static ExpandoObject ToExpando ( this string that) { ExpandoObject result; try { result = JsonConvert.DeserializeObject<ExpandoObject>(that, new ExpandoObjectConverter()); } catch (Exception e) { throw e; } return result; } Here we use JsonConvert.DeserializeObject, you need to add reference to NewtonSoft.Json see below. 1 2 3 using Newtonsoft.Json ; using Newtonsoft.Json.Converters ; using Newtonsoft.Json.Linq ;

Here's how to convert XML to an ExpandoObject using recursion. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 public static dynamic ToExpando ( this XDocument document) { return CreateExpando (document.Root); } private static dynamic CreateExpando (XElement element) { var result = new ExpandoObject() as IDictionary< string , object >; if (element.Elements().Any(x => x.HasElements)) { var list = new List<ExpandoObject>(); result.Add(element.Name.ToString(), list); foreach ( var childElement in element.Elements()) { list.Add(CreateExpando(childElement)); } } else { foreach ( var leafElement in element.Elements()) { result.Add(leafElement.Name.ToString(), leafElement.Value); } } return result; } Happy Coding!

Automatically Discover and Assign Parameter with Values to a Stored Procedure Call in C#

-
I'm sure most programmers have run across a situation wherein they have to pass  a lot of parameters to a stored procedure call in C#. Instead of manually typing each parameter in and assigning a value, why not develop a way to automatically discover the parameter, add it to the parameter list of the command object and assign the corresponding value from an entity or model. Here's my implementation using extension method. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 /// <summary> /// Automatically assigns parameters to Command.Parameter Collection from List of parameter names /// </summary> /// <param name="that">Command object being extended</param> /// <param name="model">Expando model</param> /// <param name="conn">sQLConnection used to g...
