Converting DataTable to a List of Entity Object

Recently some one asked me how should i need to convert a DataTable to an List of Entity Object. Let me Explain in detail below…

Let say we have following Entity Class called Testimonial with two properties i.e.., Comment and Commentedby here Comment is the property where we have the actual comment by the User and Commentedby is the property to store the name of the User who commented it.

 public class Testimonial
        public string Comment { get; set; }
        public string Commentedby { get; set; }

Now we need to get these Testimonial data from data source it may be from Database / XML file / CSV File etc.., we use XML file for this example . Now using linq we Enumerate the collection of dataRows in the datatable and create a list of Testimonials as shown below

List<Testimonial> lstTestimonial = new List<Testimonial>();

 string strpath = System.IO.Path.Combine(AppDomain.CurrentDomain.GetData(“DataDirectory”).ToString(), “Testimonials.xml”);
            DataSet ds = new DataSet();

            if (ds != null && ds.Tables.Count > 0)
                lstTestimonial = (from r in ds.Tables[0].AsEnumerable()
                                  select new Testimonial
                                      Comment = r.Field<string>(“Comment”),
                                      Commentedby = r.Field<string>(“Commentedby”)

Note this is the best way to convert because due to strong data-type using Field Method, we can rectify any type conversion issues at Compile time.

Hope this short explanation (due to insufficient time) Helps you… Please comment me in any case…

Happy Coding 🙂

Adding a new record to an IQueryable variable

Hi All,

Recently working on one of my application using Linq, i need to fill the datagridview with selected rows and columns which i can get from querying a list of objects using Linq. Now for every result i need to add an additional static record to the grid view. for this i need to have this record as a last record for my selected IQueryable variable from LINQ result.  Let me show you through example what i said till now…


var varresult = from r in lstobject select new { COLUMN1 = r.Title, COLUMN2 = r.Price };

DataGridView1.datasource = varresult ;


Now i need to add a new static record (i.e.., new{COLUMN1=”Discount Price”, COLUMN2=10}) to the existing varresult object…

varresult  = varresult.ToList().Union(new[] { new{COLUMN1=”Discount Price”, COLUMN2=10}});

DataGridView1.datasource = varresult ;



thats it Now a last record will be what you want… Please note that the variables and there types should be same as result object had.

Hope this Helps u…


Happy Coding 🙂
