Hello, The code below converts a DataTable object to generic List object using LINQ and C#. It assumes that the DataTable columns match with class properties. C# Code 1 2 3 4 5 6 7 8 var personEnumerable = table.AsEnumerable(); List<Person> ListPosition = new List<Person>(); ListPosition = ( from item in personEnumerable select new Person { ID = item.Field< int >( "ID" ).ToString(), Salary = item.Field< double >( "Salary" ).ToString() }).ToList(); Class 1 2 3 4 5 public class Person { public string ID { get ; set ; } public string Salary { get ; set ; } }

So, the workaround is to encode the cookie value first and then assign the appropriate encoding before saving it to the cookie container object. 1 2 ccC

Good evening! Given total number of minutes as input and you need to extract the total number of hours and remaining minutes out from the input, you need to use the TimeSpan class specifically FromMinutes() method. Based from the docs ,the FromMinutes method returns a TimeSpan object that represents a specified number of minutes, where the specification is accurate to the nearest millisecond. C# Code 1 2 3 4 TimeSpan span = TimeSpan.FromMinutes(1506); var hours = ( int ) span.TotalHours; var minutes = span.Minutes; Console.WriteLine(hours + ":" + minutes.ToString( "D2" )); VB.NET Code 1 2 3 4 Dim span As TimeSpan = TimeSpan.FromMinutes(1506) Dim hours = CInt (span.TotalHours) Dim minutes = span.Minutes Console.WriteLine(hours + ":" + minutes.ToString( "D2" )) Output
