c# - Generic Delete in Entity Framework -

i have generic delete method dodelete<mytable>(int batchsize, mydatabasecontext)

this methods builds ids (list<int> deleteid) upto batchsize count , call

bulkdelete<t>(mydatabasecontext, t => deleteid.contains(t.recordid))  

however approach not work because unaware <t> has property recordid (even though recordid property).

i have tried:

int rows = bulkdelete<t>(mydatabasecontext, "recordid in (100001,100002)"); 

this actual method delete, have overload accepts string predicate.

public int bulkdelete<t>(mydatabasecontext context, expression<func<t,   bool>> predicate) t : class {     int rows = context.set<t>().where(predicate).delete();      return rows; } 

as @mason says, can create interface recordid property entities implement, generic t=>deleteid.contains(t.recordid) compile:

// interface public interface irecordidentity {     int recordid {get;set;} }  // sample class public class person : irecordidentity {    // implement interface    public int recordid {get;set;}  }  // generic bulkdelete irecordidentitys public int bulkdelete<t>(mydatabasecontext context, expression<func<t, bool>> predicate)     t : irecordidentity {     int rows = context.set<t>().where(predicate).delete();      return rows; }  // sample call bulkdelete<person>(mydatabasecontext, t=> deleteid.contains(t.recordid))  

now bulkdelete() restricted working on types implementing irecordidentity predicate valid.
