Question

I would like to write to a text file, but I have small problem. When use the code below, it writes just once.

        StreamWriter fileWriter = new StreamWriter("test.txt");
        fileWriter.WriteLine(jointHead.Position.X);       
        fileWriter.Close();

When I write like this:

        Debug.WriteLine(jointHead.Position.X);

it writes the X position until I close the application. How can I write to a text file like I write in Debug mode until I close the application. If I take fileWrite.Close() from where it stays, the program doesnt work.

Thank you…

Try

StreamWriter fileWriter = new StreamWriter("test.txt", true);
        fileWriter.WriteLine(jointHead.Position.X);       
        fileWriter.Close();

This will allow text written to be appended to the end of the file.
At the moment your writing from the beginning each time.

edit

If you wish to clear the file at the start of the application then just perform the following:

StreamWriter fileWriter = new StreamWriter("test.txt");
            fileWriter.Write("");  
            fileWriter.Close();
