c# - Mapping A Property Of List<T> Using Automapper -

using automapper, want map property list of type employee using string.join() product comma-delimited string of names of employee's rights. here classes i'm using:

public class mappedemployee {     public string name { get; set; }     public string rightnames { get; set; } }  public class employee {     public string name { get; set; }     public list<right> rights { get; set; } }  public class right {     public string name { get; set; } } 

and here code have:

mapper.createmap<employee, mappedemployee>()     .formember(d => d.rightnames, o => o.mapfrom(s => s.rights.selectmany(r => string.join(", ", r.name))));  var employee = new employee {     name = "joe schmoe",     rights = new list<right>     {         new right { name = "admin" },         new right { name = "user" },     } };  var mappedemployee = mapper.map<employee, mappedemployee>(employee); 

however, it's producing folowing:

system.linq.enumerable+<selectmanyiterator>d__14`2[employee.right,system.char] 

what can do comma-delimited string of employee's rights?

try using resolveusing instead , putting string.join before selection:

mapper.createmap<employee, mappedemployee>()     .formember(d => d.rightnames, o => o.resolveusing(s => string.join(", ",s.rights.select(r =>  r.name))));
