CreateDirectory() and WriteXML - No Access (UnauthorizedAccessException)

Question

I have the problem that I create a folder with CreateDirectory(@exportPath). The Problem is my i have no access to write in that created Folder with ds.WriteXml(exportPath);.

Is there a possible way to create rights to access with the CreateDirectory Method?

                    Directory.CreateDirectory(@exportPath);

                    ....

                    sqlDataAdapt = new SqlDataAdapter(sqlQuery, sqlCon);
                    DataSet ds = new DataSet();
                    sqlDataAdapt.Fill(ds);


                    ds.WriteXml(exportPath); 
                    ds = null;

You cannot specify a path outside of the Web application.

• HttpServerUtility.MapPath(String) Method

• Server.MapPath() In ASP.NET

• ASP.NET MapPath: Virtual and Physical Paths
