RE: Dropping carriage return characters from web service

Hello Rgliane,

Regarding on the CR(X0D) LF(x0A) characters issue, it is actually due to
the response conversion(in the client proxy's internal code) against the
string data in soap response message. Based on my tracing, both the 0D
and 0A chars are correctly sent back to the client-side, however, it is in
the SoapHttpClientProtocol(base class of client proxy)'s code, when it read
the content from the response stream, for string value, it will filtered
the "0A" char. I haven't got the exact code logic, based on reflector's
diassembled code, it is during the "ReadResponse" method.

So far I think for string type parameter or return value, it will force
this normalizing rules on the control character, if you do need to get the
exact character list, I suggest you consider transfer the string as byte
array (encoding it before transfer and decode it after received). e.g.

=========================
[WebMethod]
public byte[] GetBinaryData()
{
string str = string.Empty;

str = "abc\r\n";


return Encoding.Unicode.GetBytes(str);

}
=====================

=======client code==========

byte[] bytes = proxy.GetBinaryData();

string str = Encoding.Unicode.GetString(bytes);

Console.WriteLine(str.Length);
=====================
