如何在VBA和C＃中编码/解码XML

Question

I currently have a program that trasfer data from VBA (Access) to C# (via ASP.NET POST). How do I encode/decode on each end?

Here is my XML read in C#:

StreamReader reader = new StreamReader(Request.InputStream);
string xmlData = "";
XmlDocument xml = new XmlDocument();
xmlData = reader.ReadToEnd();
XmlElement rootXML;
xml.LoadXml(xmlData);
rootXML = xml.DocumentElement;

Here is my XML write in C#:

Response.Clear();
Response.ContentType = "text/xml";
Response.Charset = "UTF-8";
Response.Write(XML_in_String);
Response.End();

Here is my XML write in VBA

connection.Open "POST", server & "www.webpage.com/" & postData, False
connection.setRequestHeader "Accept", "application/xml"
connection.setRequestHeader "Content-Type", "application/xml"
connection.send "<?xml version=""1.0"" encoding=""UTF-8"" ?><data>" & outXMLstr & "</data>"

Here is my XML read in VBA

Dim inXML As MSXML2.DOMDocument
Set inXML = New DOMDocument
inXML.loadXML (connection.responseText)

Specifically, I got an error in C# when trying to loadXML(xmlData) because it can't parse the ampersand (&).

On your xmlData , have you tried as @HatSoft says, to use Server.HtmlEncode / Server.HtmlDecode ? That way you could get rid of htmlentities that doesn't work in XML.

Or you could wrap your data into a CDATA-field
