c# - Getting the name of the variable during whose processing an exception has occurred? -

i have function use validation

    public void validate()     {         action<list<field>> validatefields = (field) =>             {                 if (field != null && field.any())                 {                     field.foreach(x => x.validate());                 }             };          new list<list<field>> { this.personelements, this.contactelements, this.miscelements }.foreach(x =>             {                 try                 {                     validatefields(x);                 }                 catch (exception e)                 {                     log.errorformat("an exception has occurred while validation of {1} : {0}", e, x.tostring()); // print x.name.tostring());                     throw;                 }             });     } 

the problem line:

  new list<list<field>> { this.personelements, this.contactelements, this.miscelements }.foreach(x => 

i need (in case exception has occurred) log

an exception has occurred while trying process "personelements / contactelements / miscelements" depending upon during validation exception has occurred.

how list variable name in case of exception occurring during processing ?

thanks in advance.

variable names meaningful in context. same object accessed different variables. reasonable provide name of collection in type tuple<string, list<field>>.

new list<tuple<list<field>>> { tuple.create("personelements", this.personelements), ... }.foreach (      ...     validatefields(x.item2);     ...     log.errorformat("an exception has occurred while validation of {1} : {0}", e, x.item1);
