Need of Generic method to convert datatable to model list

public static class Common_Method 
{  
    public static List < T > ConvertToList < T > (DataTable dt) 
     {  
        var columnNames = dt.Columns.Cast < DataColumn > ().Select(c => c.ColumnName.ToLower()).ToList();  
        var properties = typeof(T).GetProperties();  
        return dt.AsEnumerable().Select(row => {  
            var objT = Activator.CreateInstance < T > ();  
            foreach(var p in properties) {  
                if (columnNames.Contains(p.Name.ToLower())) {  
                    try {  
                        p.SetValue(objT, row[p.Name]);  
                    } catch (Exception ex) {}  
                }  
            }  
            return objT;  
        }).ToList();  
    }  
}  

Example

Below is the function to get the list of students in which we are using the generic method to convert our data table result to List of Model "Employee".

public List < Employee > GetEmployeeList() 
{  
    Datatable Result_dt = new DataTable();  
    Result_dt = _DataBAL.GetData(); 
    List < Employee > Employeelist = new List < Employee > ();  
    Employeelist = Common_Method.ConvertToList < Employee > (Result_dt);  
    return Employeelist;  
}

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.
