"High" : "Low" , //Here I want to manage that contition. } How can I do that?

public class DocumentsUser { public string Priority { get ; set ; } } List objUserSetUp = objUserSetUp1.Select(m => new DocumentsUser() { Priority = GetPriority(m. Priority ); } ) public string GetPriority( int priority) { switch (priority) { case 1: return "Low" ; break ; case 2: return "Medium" ; break ; case 3: return "High" ; break ; Default: return "Low" ; break ; } }

@Fabio, Agreed in principle. However, just for record, specific to xml serialization, enum values can be decorated with an attribute as follows: [ XmlEnum ( Name = "High" )]

Fabio Silva Lima · Answer

@Nitin I agree but it depends what he is trying to do. He can face a serialization problem with enum. If the frontend expects an integer when we use enum it's serialize as string and other problems with database. @Ujjwal I do not like to use switch because a new priority you will need to add one more case. But i liked you separate method for the conversion.

Nitin Sontakke · Answer

Even better approach would be to have a property of enum's type as: public PriorityType Priority {get; set;}

Fabio Silva Lima · Answer

create a enum and convert Priority. public class DocumentsUser { public string Priority { get ; set ; } } public enum PriorityType{ High = 3, Medium = 2, Low = 1 } var objUserSetUp = objUserSetUp1.Select(m => new { Priority = (PriorityType)m.Priority});
