XML data access through Linq..


Following are the setp to read data from XML file using linq query

1st : Add following name spaces by using

using System.Xml;
using System.Xml.Linq;

2nd : Create XDocument object and load XML file

XDocument objXDocument = XDocument.Load(Server.MapPath("~/App_Data/XYZ.xml"));

3rd : Write following linq query to read data from XDcument object

var q = from c in loaded.Descendants("Iteams")
                    select c.Elements("Item");

You can also specify where condition like following

var q = from c in loaded.Descendants("Items")
                    where c.Attribute("id").Value = "id1"
                    select c.Elements("Item");

4th : Check for null and then convert var object 'q' to List

List<XElement> objElem = q.ToList()[0].ToList();


Following is the structuer of the XML file used for this code

<? xml version="1.0" encoding="utf-8" ?>
<Items>
  <Item id="id1">
  ...
  Item>
  <Item id="id2">
  ...
  Item>
  <Item id="id3">
  ...
  Item>
Items>

LINQ union with group by

In my recent development activity with LINQ query, I need to get the some of user points from tow different tables where user's points are based on some activities. There are many users who are into one table but not in another table and some are in both table. For example tables having data like this Table 1 UserID   Points 1           10 2           20 Table 2 UserID    Points 2           20 3           30 Result should be UserID    Points 1           10 2           40 3           30 I try to get this result with LINQ query using joins and group by samples from the web. I had googling to get something useful but dont get any success. So I try with new logic and here it is, I think it will help full to other also. Example Item class to use public class Item {   public int ID { get ; set ; }   public int Total { get ; set ; }   public Item()   {   }   public Item( int ID, int Total)   {     this .ID = ID; this .Total = Total;   }

Following is C# code to get the  SqlConnection from ObjectContext.Connection . This is usefully to run dynamically created query using ADO.NET using connection string specified into the EDMX ObjectContext object. C# Code Example : using ( EntityContext context = new EntityContext ()) { EntityConnection ec = ( EntityConnection )context.Connection; SqlConnection sc = ( SqlConnection )ec.StoreConnection; SqlDataAdapter da = new SqlDataAdapter (strQuery, sc); DataSet ds = new DataSet (); da.Fill(ds); return ds.Tables[0]; }

Get Tables and Columns Names by LINQ

Here I am explaining one of the tricks to get all table name list along with column of it from your DataContext. I am using the System.Data.Linq.Mapping.MetaModel to get information about tables and it have much more database related information. Following are the code to list all table name along with column from your DataContext. //DataContext object. DataClassesDataContext DB = new DataClassesDataContext ();         //String variable to stor html to render. string strHtmlToLoad = "" ;         //Heading strHtmlToLoad = "<-h2->Table Names<-/h2-><-ol->" ;         //Loop through tables add name to string foreach ( var mTable in DB.Mapping.GetTables()) { strHtmlToLoad += "<-li->" + mTable.TableName + "<-ul->" ; //Loop through table's columns add name to string foreach ( var mColumn in mTable.RowType.DataMembers) strHtmlToLoad += "<-li->
