Run an App Query multiple times on the same page

The previous examples showed how to use a Query. Now we want to run the query twice, which requires a Reset().
Note that the parameter SiteId is preset to be [Site:Id].

Initial Code

The following code runs at the beginning and creates some variables/services used in the following samples.

@{
   // Different query in DNN / Oqtane - eg. "SqlTop10FilesDnn"
   var queryName = "SqlTop10Files" + CmsContext.Platform.Name;

   // get the query and ask for the "Default" results as a dynamic List
   // This case doesn't set parameters, so we're using the defaults (current site)
   var query = Kit.Data.GetQuery(queryName);
   var currentFiles = AsList(query);

   // Get a fresh query, so we can use again with other parameters
   query = Kit.Data.GetQuery(queryName, parameters: new { 
     SiteId = CmsContext.Platform.Name == "Dnn" ? 0 : 1
   });
   var rootFiles = AsList(query);
 }
