c# - FileHelpers Library: AfterReadRecord Compilation Error -

i'm hoping there's expert in using filehelpers library here.

i'm using 2.9.9 stable version nuget , trying use afterreadrecord event handler test if fields empty.

the code have shown in simplified form below:

public class test {  public class myclass  {   public string name;  }   public static void engine_afterreadrecord(enginebase engine, filehelpers.events.afterreadeventargs<myclass> e)  {   if (string.isnullorwhitespace(e.record.name))   {    throw new invaliddataexception("name required");   }  }   public void readcsv()  {   filehelperengine engine = new filehelperengine(typeof(myclass));   engine.options.ignorefirstlines = 1;   engine.errormanager.errormode = errormode.saveandcontinue;   engine.afterreadrecord += new filehelpers.events.afterreadhandler<myclass>(engine_afterreadrecord);  } } 

there's compilation error on last line in readcsv file. error is:

cannot implicitly convert type 'filehelpers.events.afterreadhandler<myclass>' 'filehelpers.events.afterreadhandler<object>' 

i'm stuck. helpers?

the problem u using version of engines don't use generics using generics in handler

try this:

  var engine = new filehelperengine<myclass>();   engine.options.ignorefirstlines = 1;   engine.errormanager.errormode = errormode.saveandcontinue;   engine.afterreadrecord += new filehelpers.events.afterreadhandler<myclass>(engine_afterreadrecord);
