Hi You have to do file check whether file exists in the position or not. Otherwise it will give the run time error. The File class provides the method to check file exists or not in the given path. you can do the check like the following. if (File.Exists(@c:	ext.txt)) { //Way1: you can use the file class to read all the lines string strcontent = File.ReadAllLines(@c:	ext.txt); //way2: you can use the stream reader class to read entire file content. StreamReader sreader = new StreamReader(@c:	ext.txt); string strcontent = sreader.ReadToEnd(); } Hope this will help you.

Try copying c:	ext.txt from your program into Windows Explorer and see what you get. I suggest copying using the clipboard; not by keying in the text. Or copy the filename and then use Ctrl-O in Visual Studio to open a file and paste the filename into there. You should do things like this when you get errors such as this because errors like this are often the result of assumptions that are not valid assumptions. Are you sure you want text and not test? You might have a slight mis-spelling. If so then the technique I describe above would give you a really big clue.
