[dotNetRDF-Develop] how can i use SPARQL to query local OWL/RDF file by using dotNetRdf library ?

[anji r. <anj...@gm...>]

Dear sir/madam,
        I have a OWL/RDF financial domain file locally which is developed
by using protege tool,
 Now i am using dotNetRDF library to query my local OWL/RDF file through
microsoft visual studio
C# programatically to get the synonym or related terms/words according to
the user input. I followed
some code from a blog, but it is giving the ERROR that file doesn't exist.
The ERROR Line is:  g.LoadFromFile(" FinancialInvestment.rdf");
I tried in different ways of giving path including of copyied file to the
project bin folder etc... but unsucceded. could u please help regarding
this....
The following code was used by me......



//Define your Graph here
IGraph g = new Graph();

//Load some data into your Graph using the LoadFromFile() extension method
g.LoadFromFile("myfile.rdf");

//Use the extension method ExecuteQuery() to make the query against the Graph
try
{
  Object results = g.ExecuteQuery("SELECT * WHERE { ?s a ?type }");
  if (results is SparqlResultSet)
  {
     //SELECT/ASK queries give a SparqlResultSet
     SparqlResultSet rset = (SparqlResultSet)results;
     foreach (SparqlResult r in rset)
     {
       //Do whatever you want with each Result
     }
  }
  else if (results is IGraph)
  {
     //CONSTRUCT/DESCRIBE queries give a IGraph
     IGraph resGraph = (IGraph)results;
     foreach (Triple t in resGraph.Triples)
     {
        //Do whatever you want with each Triple
     }
  }
  else
  {
     //If you don't get a SparqlResutlSet or IGraph something went wrong
     //but didn't throw an exception so you should handle it here
     Console.WriteLine("ERROR");
  }
}
catch (RdfQueryException queryEx)
{
   //There was an error executing the query so handle it here
   Console.WriteLine(queryEx.Message);
}
