In this article, you will learn how to convert DataTable to LINQ Anonymous Type c#

protected static List<T> ToAnonymousCollection<T>(DataTable dt, T anonymousObject)
{
    List<DataColumn> dataColumns = dt.Columns.OfType<DataColumn>().ToList();

    return dt.Rows.OfType<DataRow>().Select(dr =>
    {
        Dictionary<string, object> dict = new Dictionary<string, object>();

        dataColumns.Each(dc => dict.Add(dc.ColumnName, dr[dc]));

        return JsonConvert.DeserializeAnonymousType(JsonConvert.SerializeObject(dict), anonymousObject);
    }).ToList();
}

Generic method to convert a datatable to generic list

private static List<T> ConvertDataTable<T>(DataTable dt)
        {
            List<T> data = new List<T>();
            foreach (DataRow row in dt.Rows)
            {
                T item = GetItem<T>(row);
                data.Add(item);
            }
            return data;
        }

        private static T GetItem<T>(DataRow dr)
        {
            Type temp = typeof(T);
            T obj = Activator.CreateInstance<T>();

            foreach (DataColumn column in dr.Table.Columns)
            {
                foreach (PropertyInfo pro in temp.GetProperties())
                {
                    if (pro.Name == column.ColumnName)
                        pro.SetValue(obj, dr[column.ColumnName], null);
                    else
                        continue;
                }
            }
            return obj;
        }

Convert DataTable to LINQ Anonymous Type c#, generic method to convert a datatable to generic list
C# is a programming language developed by Microsoft that runs on the .NET Framework. C# is used to develop web, desktop, mobile, games and much more application. C# is a object-oriented programming language developed by Microsoft within its .NET Framework. Led by Anders Hejlsberg, your basic C# programming and will also take you through various advanced concepts related to C# programming language. C# such as control statements, objects and classes, inheritance, constructor, destructor, this, static, sealed, polymorphism, abstraction, abstract class, interface, File IO, Collections, namespace, encapsulation, properties, indexer, arrays, strings, regex, exception handling, multithreading etc. For example... using System; namespace MinifyCode { class Program { static void Main(string[] args) { Console.WriteLine("Hello Minify Code"); } } } Output: Hello Minify Code In this article you will learn, what is server side controls. We will discuss each of these objects in due time. In this tutorial we will explore the Server object, the Request object, and the Response object. Session Application Cache Request Response Server User Trace Server Object The Server object in Asp.NET is an instance of the System.Web.HttpServerUtility class. The HttpServerUtility class provides numerous properties and methods to perform many type of jobs. Methods and Properties of the Server object The methods and properties of the HttpServerUtility class are exposed through the intrinsic Server object provided by ASP.NET. using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Optimization; using System.Web.Routing; using System.Web.Security; using System.Web.SessionState; using System.Data.Entity; namespace minifycode { public class Global : HttpApplication { void Application_Start(object sender, EventArgs e) { // Code that runs on application startup RouteConfig.RegisterRoutes(RouteTable.Routes); BundleConfig.RegisterBundles(BundleTable.Bundles); // Initialize the product database.
