DataSet.ReadXml fails when a percentage (%) sign is in the filename followed by 2 hex characters

CB
Using C# in .Net 2003, DataSet.ReadXml fails when a percentage (%) sign
is in the filename followed by 2 hex characters. Seems that the %
sign is likely encoding the following 2 hex characters. So
c:\test%ab.xml fails for ReadXml since %ab is interpreted as 171 and
c:\test171.xml does not exist. There is no problem with c:\test%mn.xml
because "mn" is not a hex code. If I replace the % sign with %25
(25hex = 37dec = ascii code for %), the ReadXml function succeeds since
it is interpreted as c:\test%ab.xml. So I had to write a workaround
function to read a filename, replace any occurance of the % character
with %25, then call ReadXml. Yuk.

I found another related post that is about 2 years old that seems to be
using VB6 rather than C#
(http://groups.google.com/group/micro...3b2311783c011).
Is there some switch in the DataSet object to ignore %encoding in the
filename? %encoding is really only used in web dev rather than windows
dev anyway right? Is there a more appropriate workaround?

CORRECTION:
"So c:\test%ab.xml fails for ReadXml since %ab is interpreted as 171
and c:\test«.xml does not exist.". (%ab hex = 171 dec = ascii code
for «)

I have written a web service in C#, .NET 1.1 which reads a XML file into a dataset. This is just a plain XML file. First I use the Dataset.ReadXmlScheme function and pass the XML file to it.

Part of an application I'm working on needs to manipulate some XML data (in an XML file), by reading the data into a DataSet using the MyDataSet.ReadXML method, and then using MyDataSet.WriteXML to update the XML file itself. However, now I want to take advantage of the Primary Key functionality of the DataSet object, so I can easier find rows (in a DataTable in the DataSet), and also easier remove rows, based on a unique key.

When I check the syntax of dataset, It seems that dataset can only read data from file. (e.g., datset.read(string filename), dataset.readxml(string filename)). If I have a string with XML format that is transfered from somewhere else, how can I read the string and populate it into a dataset, then display the data in a data grid? Thanks for any help.
