how can i convert decimal value to AScii , i have tried with

var charStrs = Convert.ToString(receivedEvent.tagData.can_Msg.data[3]) +
               Convert.ToString(receivedEvent.tagData.can_Msg.data[4]) + 
               Convert.ToString(receivedEvent.tagData.can_Msg.data[5]) + 
               Convert.ToString(receivedEvent.tagData.can_Msg.data[6]) + 
               Convert.ToString(receivedEvent.tagData.can_Msg.data[7]);
var asStr = String.Concat(charStrs.Select(cs => (char)Int32.Parse(cs, NumberStyles.HexNumber)));

i know that my decimal number = 56 49 50 48 48 48 53 56 50 56 and when converting it to ascii i will get 8120005828;but i get error in NumberStyles.HexNumber its seems it does not work on wpf ?
