C # LINQ Query dynamic by

Grouplist is the raw data set,list<t>

SortOrder is the sort type, desc or ASC

Sortname is the Sort property name

1. Use reflection.

Private Static ObjectGetPropertyValue (ObjectObjstringProperty ) {System.Reflection.PropertyInfo PropertyInfo=obj. GetType ().      GetProperty (property); returnPropertyinfo.getvalue (obj,NULL);} varResultlist = SortOrder = ="desc"? Grouplist.orderbydescending (p = getpropertyvalue (P, sortname)): Grouplist.orderby (p =GetPropertyValue (P, sortname));//LINQ mode://varResultList1 = fromPinchGrouplist byGetPropertyValue (p, M.sortname)Selectp;if(SortOrder = ="desc") ResultList1= fromPinchGrouplist byGetPropertyValue (p, Sortname)Descending SelectP

2. Call AsQueryable ()

Converts a generic system.collections.generic.ienumerable<t> to a generic system.linq.iqueryable<t>.

var groupquerylist = grouplist.asqueryable (); //  Here var tmplist = groupquerylist. (Sortname, SortOrder);
