I think you use 'xmlfile' as path to your xml. check that string. it is not a real path.

Actually I getting this xml from server, saving it as a string, passing it to DataSet

The "Illegal characters" exception means that the file path string you are passing to ReadXml is wrong: it is not a valid path. It may contain '?', or ':' in the wrong place, or '*' for example.

You need to look at the value, check what it is, and work out where the illegal character(s) are coming from.

As I noticed no such characters in my XML string.
Any method is available to check for illegal characters.?

It's not the "xml string" that's the problem: it's the path to the file containing the XML that's the problem.

DataSet.ReadXML uses the string you pass to it as a file name, not as the actual XML to process:

If you want to pass "raw" XML, then you need to wrap it in a stream, and pass that instead:
