StreamReader C#

While reading a text file(which contains the location of a file to be exported to a database) using the streamReader function in C#, how can I add a confirmation message to the code that will be displayed in the command prompt window(console application) so that I know the file got read and was exported?

public class Script
{
    public static void Main(string[] args)
    {
        // Prepare the type that will handle all of the exporting needs
        FileExporter exporter = new FileExporter();

        try
        {
            //create an instance of StreamReader to read from a file.
            //The using statemen also closes the StreamReader.
            using (StreamReader sr = new StreamReader("ScriptFile.txt"))
            {
                string filePath;
                //read and display lines from the file until the end of
                //the file is reached.
                while ((filePath = sr.ReadLine()) != null)
                {
                    // Throw error if file does not exists to terminate the process.
                    if (!File.Exists(filePath))
                    {
                        string msg = string.Format("File not found at {0}.", filePath);
                        throw new FileNotFoundException(msg);
                    }

                    // Set the name of the export to be the name of the file.
                    string exportName = new FileInfo(filePath).Name;

                    // Export image as an SHP file if the extension matches.
                    if (filePath.Contains(".shp"))
                    {
                        exporter.processSHP(filePath, exportName, "");
                        //need confirmation that exporter.processSHP occured <<<-----***
                    }
                    else
                    {
                        string fileExtension = filePath.Split('.')[filePath.Split('.').Length - 1];

                        exporter.processIMG(filePath, exportName, "", fileExtension); 
                        //need confirmation that exporter.processIMG occured <<<-----***
                    }
                }
            }
        }
        catch (Exception e)
        {
            Console.WriteLine(
                string.Format("Process terminated. An error has occurred: {0}", e.ToString()));
        }
    }

Add this:

Console.WriteLine("Done reading & Exporting");

above

}
catch (Exception e)
{

Don't forget the Console.ReadKey() in case you want to actually see it up there

After you read the file to the end and look for your match (assuming you have something like a boolean value to let you know the export happened and a match was found) you can check the EndOfStream property in the streamreader and output the message. Or you can just check your match value to see if it returned true.

use flush and then close on your writer object.

then write done to console.
