simply convert it to Enumarable and then loop through it using linq var ContactList= ds.Tables[0].AsEnumerable() .Select(dataRow => new Contact() { Name = dataRow.Field string >( "Name" ), PhoneNumber= dataRow.Field int >( "PhoneNumber" ) }).ToList();

i have just given you an example if you datatable contains information about employee then you need to create a class with employee and then take its object for example var EmployeeList= ds.Tables[0].AsEnumerable() .Select(dataRow => new Employee() { Name = dataRow.Field string >( "Name" ), // dataset col 1 PhoneNumber= dataRow.Field int >( "PhoneNumber" ) //col 2 }).ToList(); public class Employee { public string Name { get ; set } public int PhoneNumber { get ; set } }
