Sorting on C# arrays using OrderBy -

-

i using orderby create new sorted array suggested in post sort array of items using orderby<> .

var sorted = sharepointlist.orderby(item => item.gettaborder()).toarray();

where, sharepointlist array of objects contains attributes including int taborder , gettaborder getter 'taborder' attribute

but throws below exception. please help

nullreferenceexception

object reference not set instance of object.

thanks in advance, sagarika

the problem have null value in sharepointlist. if do;

  var sorted = sharepointlist.where(x => x != null).orderby(item => item.gettaborder()).toarray();

it prevent exception, null values excluded result.

your entire list null in case need; 

     if (sharepointlist != null)           //order in here      else          //handle error
