Convert pdf file received in string variable to byte array in C#

Question

I am trying to develop an application in C# which takes data from Service1(3rd party), processes it and then sends data to Service2(again 3rd party).

The data I am tryin

Answer 1

I just found that it was not Service1 which was sending data in string format, it's just I was using IRestResponse.Content, a string variable from RestSharp instead of using IRestResponse.RawBytes, a byte[] variable.
