Question

I have string of text that needs to be cnoverted to base64 before being posted to a url.
Here is my code

  HttpWebRequest req = (HttpWebRequest)WebRequest.Create(uri);
      byte[] postDataBytes = Encoding.UTF8.GetBytes(strCXML);
       string returnValue = System.Convert.ToBase64String(postDataBytes);
       req.Method = "POST";
       req.ContentLength = postDataBytes.Length;
       req.ContentLength = postDataBytes.Length;
       Stream requestStream = req.GetRequestStream();
       requestStream.Write(returnValue,0, postDataBytes.Length);

Problem is i get error on the last line System.IO.Stream.Write(byte[],int,int)
returnValue is base64 string cant be used as byte[] needed in stream.writer
Any idea how to take that that base64 string called returnvalue and put it to a url
thanks

Answer 1

You are using a Stream as your requestStream. Stream.Write takes a byte array, not a Base64 string.

I think you are doing it in the wrong order. I would convert strCXML to a Base64 String first then encode it into a byte array to write to the request stream.
