Post and XML issue

[Fred]

Hello,

I am having a problem with a multiline string that I create from a byte
array (xml file). I am using StringBuilder and Ecoding the string to ASCII
(code below).

/ Upload the NameValueCollection.
byte[] responseArray =
myWebClient.UploadValues("https:\\test.com\test.as px","POST",
myNameValueCollection);
// used to build entire input
StringBuilder sb = new StringBuilder();
string tempString = null;
string response = "";
tempString = Encoding.ASCII.GetString(responseArray);
sb.Append(tempString);
response = sb.ToString();

The response still is multi-line with the xml being cut off in elements.
Example:
..... <no
de1/>..... <element1>te
<element1/>

I have tried this code to remove carraige returns, new lines...
response = response.Replace("\r", "").Replace("\t", "").Replace("\n", "");
It removes these characters in the string but leaves the fragmented xml
string. I have also tried UTF8 with no luck and have used Regex too. The
problem is the app I am posting to is returning a formatted xml and when I
convert the byte array to a string the string gets fragmented. I need to
store it
as a string however is there a way to convert the initial byte array into a
xml document? Or do you have an other ideas?

Thanks
