c# - How to map a collection using CSV Helper -

public class template : entity {     public template()     {         templateitems = new list<templateitem>();     }      public int id { get; set; }     public string name { get; set; }     public virtual icollection<templateitem> templateitems { get; set; } }   public class templateitem : entity {     public int id { get; set; }     public int templateid { get; set; }     public string name { get; set; }     public virtual template template { get; set; } }   public sealed class templatemap : csvclassmap<template> {     public templatemap()     {         map(m => m.name).name("name");         //map(m => m.templateitems).convertusing(row => new list<string> { row("nodetype") });          // how map collection value csv column      } } 

i reading csv file , need map csv columns 2 different tables have 2 different models tables ie template , templateitem templateitem mapped template how map csv class ?

currently not possible. need manually handle collections. 1 way of doing use convertusing, if want keep in mapping file.

here example:

void main() {     using (var stream = new memorystream())     using (var writer = new streamwriter(stream))     using (var reader = new streamreader(stream))     using (var csv = new csvreader(reader))     {         writer.writeline("1,a,b,c");         writer.writeline("2,d,e,f");         writer.flush();         stream.position = 0;          csv.configuration.hasheaderrecord = false;         csv.configuration.registerclassmap<testmap>();         csv.getrecords<test>().dump();     } }  public class test {     public int id { get; set; }     public list<string> names { get; set; }  }  public class testmap : csvclassmap<test> {     public testmap()     {         map(m => m.id);         map(m => m.names).convertusing(row =>         {             var list = new list<string>();             list.add(row.getfield( 1 ));             list.add(row.getfield( 2 ));             list.add(row.getfield( 3 ));             return list;         });     } }
