Thread: 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();
                            }
