关于如何使用c#和asp.net读取RDF的建议

我是语义网的新手，我创建了一个本体，我需要开发一个网站，可以读取本体并从OWL文件中提取信息并在网站中显示我做了一些关于我需要使用哪个库的研究，所以我发现RDFdotnet在最好的库中，我需要使用它来读取owl文件我也发现了一个代码，但我需要有人解释或帮助我用这个代码来阅读我的猫头鹰文件。我想使用下拉列表和按钮有什么建议吗?

这是代码

//Define your Graph here - it may be better to use a QueryableGraph if you plan
//on making lots of Queries against this Graph as that is marginally more performant
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);
}
