Unable to connect csv file using oledb provider

Hi,

I am using this function to get dataset from csv file:

public static DataSet GetDataset(string filePathName, string  fileName, string fieldNames)
{
OleDbConnection CSVConnection = new  OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" +  filePathName + ";Extended Properties='text;HDR=Yes;FMT=Delimited(,)';");
             OleDbCommand CSVCommand = new OleDbCommand(@"SELECT " +  fieldNames + " FROM [" + fileName + "]", CSVConnection);
             OleDbDataAdapter CSVAdapter = new  OleDbDataAdapter(CSVCommand);
             DataSet CSVDataSet = new DataSet();
             try 
             {
                 CSVConnection.Open();
                 CSVAdapter.Fill(CSVDataSet);
                 return CSVDataSet;
             }
             catch(Exception ex)
             {
                 return CSVDataSet;
             }
             finally
             {
                 CSVConnection.Close();
                 CSVConnection.Dispose();
             }
}

But, I am getting following error on server while reading csv file using oledb provider
