c# - How to pass an array of OrderBy expression to a method? -

i'm trying enhance repository 1 responsible ordering. i've applied answer this question , far repository concerned, i'm pretty sure done.

the problem i'm running i'm not sure how pass array methods in repository. compiler keeps yelling @ me delegates. in linked question above, author doing want must possible.

here's repository code:

public virtual ilist<tentity> selectorderedlist(     expression<func<tentity, bool>>[] orderers,     bool ascending = true) {     iorderedqueryable<tentity> temporaryqueryable = null;      foreach (expression<func<tentity, bool>> orderer in orderers) {         if (temporaryqueryable == null) {             temporaryqueryable = (ascending ? this.objectset.orderby(orderer) : this.objectset.orderbydescending(orderer));         } else {             temporaryqueryable = (ascending ? temporaryqueryable.thenby(orderer) : temporaryqueryable.thenbydescending(orderer));         };     };      return temporaryqueryable.tolist(); } 

on side note, i'm not 100% sure i'm supposed use expression<func<tentity, bool>>. reason have feeling it's supposed expression<func<tentity, int>>, i'm not sure.

anyway, appreciate if can show me how call that. bonus points , love if can make work params argument.

public virtual ilist<tentity> selectorderedlist(     params expression<func<tentity, icomparable>>[] orderers) {     iorderedqueryable<tentity> temporaryqueryable = null;      foreach (expression<func<tentity, icomparable>> orderer in orderers) {         if (temporaryqueryable == null) {             temporaryqueryable = this.objectset.orderby(orderer);         } else {             temporaryqueryable = temporaryqueryable.thenby(orderer);         };     };      return temporaryqueryable.tolist(); } 

then use selectorderedlist(o1 => (o1.something), o2 => (o2.somethingelse))...

also, write descending :)

if want one, each orderer can ascending or descending, replace signature tuple>,sortdirection> cannot use implicitly typed lambdas implicitly typed tuples (and cannot use them implicit expressions either) then, you'd have quite ugly code when using it...
