This occurs due to not understanding the expected parameter type for the XmlDocument.Load("filename") method. This method expect a file name.

Look at the following example, this throw the above error.

eg:
//getting a soap response
string sXml = nc.CurrencyExchangeRatesForWeb();
XmlDocument doc = new XmlDocument();
doc.Load(sXml);

To avoid this error, we can use XmlDocument.LoadXml("string") method, following example shows the solution,

eg:
string sXml = nc.CurrencyExchangeRatesForWeb();
XmlDocument doc = new XmlDocument();
doc.LoadXml(sXml);

Happy coding
