LINQ orderby int array index value -

using linq sort passed in int arrays index.

so in code below attribueids int array. i'm using integers in array clause results in order in while in array.

 public list buildtable(int[] attributeids) {     using (var dc = new mydc())     {         var ordering = attributeids.tolist();          var query = att in dc.dc.ecs_tblattributes                     attributeids.contains(att.id)                     orderby(ordering.indexof(att.id))                     select new common.models.attribute                     {                         attributeid = att.id,                         displayname = att.displayname,                         attributename = att.name                     };          return query.tolist();     } } 

i recommend selecting attributeids array instead. ensure items correctly ordered without requiring sort.

the code should go this:

var query =  id in attributeids let att = dc.dc.ecs_tblattributes.firstordefault(a => a.id == id) att != null select new common.models.attribute {     attributeid = att.id,     displayname = att.displayname,     attributename = att.name };
