    Reading from a file and comparing the text to a string

    Hi,
    I am currently writing a program to scan through some files, find a string (or preferably keywords), Print the line to a file and count how many times it occurs. However each time I test the input string using an if statement, I get a positive result as long as the file contains some sort of text.

    I am new to c# so it is probably a misunderstanding of the classes I'm using but any help will be appreciated.

    Thank you
    Note: I am not at the stage of writing the results to a file yet, I am writing to the console for testing purposes.

    Code:
     using (StreamReader read = File.OpenText(file))
                               {
                                    string line;
                                    while ((line = read.ReadLine()) != null)
                                    {
                                        if (line.Contains("Test String")) ;
                                        {
                                            count++;
                                            
                                            Console.WriteLine(count);
                                            Console.WriteLine(line);
                                        }
                                        
                                    }
                                    read.Close();
                                }

    I'm sorry just noticed a ';' after the if statement, it's not working now, happy days...
