c# - Unable to read key value pair from hashtable -

i writing specflow test service. reading table , storing key,values in hashtable.

here sample of feature file:

    |index|id | message|     |test1|1   | aa|     |test2|2   | bb | 

here how read data table

    public hashtable getdata(table table)     {         var data = table.createset<specflowdata>();         var hashtable = new hashtable();          foreach (var currentrow in data)         {             var key = currentrow.index;             var value = getvalues(currentrow);             hashtable.add(key, value);          }         return hashtable;     } 

here trying extract key , value pair in hashtable

     [when(@"the test data submitted service")]     public void whenthetestdataissubmittedservice()     {     // table data stored in textcontext         var message = testcontext.messages;         byte? result = null;          foreach (hashtable entry in message)         {             var values = entry.values;             // problem area             foreach (hashtable item in  values)             {             var ids = item["id"];             var messages = item["message"];              // send message service accepts string,string input             sendmessageresult = client.sendmessagetoservice((string)appids, (string)messages);             }          }       } 

since values have own key value pair ..i tried access in second loop not looping collection of hashtable values.

i don't understand why can't loop value collections in second loop

once replace hashtable dictionary able access data.
