I finally did myself and used the *C# class HttpClient* to make the web request for the Solr API URL as follows.
string solrTargetDIHUrl = "http://localhost:8983/solr/dih/dataimport?command=delta-import"; ////Makes Async call to the Web API URL & trigger the data import handler action. try { using (var solrClient = new HttpClient()) { var resultObj = solrClient.GetAsync(new Uri(solrTargetDIHUrl)).Result; Console.ForegroundColor = ConsoleColor.Green; Console.WriteLine("\t\t Data Import Triggered Successfully !"); Console.ResetColor(); } } catch(Exception ex) { Console.WriteLine("ERROR in DIH Trigger >>>>> " + ex.Message + "||" + ex.StackTrace); } -- Sent from: http://lucene.472066.n3.nabble.com/Solr-User-f472068.html
