End Module. The FileInfo. CreateText method creates and opens a file for writing UTF-8 encoded text. If file already exists, this method opens the file. The following code snippet creates a file using the CreateText method that returns a StreamWriter object.

The WriteLine method of SteamLine can be used to add line text to the object and writes to the file. This code rethrows all the exceptions that may occur when writing text to the file.

You can reduce the likelihood of exceptions by using Windows Forms controls such as the OpenFileDialog and the SaveFileDialog components that limit the user choices to valid file names.

Using these controls is not foolproof, however. The file system can change between the time the user selects a file and the time that the code executes. Exception handling is therefore nearly always necessary when with working with files.

If you are running in a partial-trust context, the code might throw an exception due to insufficient privileges. For more information, see Code Access Security Basics. Where are you stuck?
