Writing to a Text File

Text files are typically organized by lines, with a line end marked by a CR/LF. When writing to a text file, you have two options:

  • Using the WriteLine() method to write some text as a line, with a CR/LF automatically added at the end
  • Using Write() to write part of a line, with no CR/LF appended

These methods have the same syntax:


In both cases, item can be string data. It can also be any simple datatype such as Integer or Double, and can also be an object reference. For non-text data items, these rules are followed:

  • For simple non-text data types, the data is converted to a string before being written to the file.
  • For object references, the object’s ToString() method is called and the result written to the file.

Here’s an example that writes some text and the current date to a file.

sw = New StreamWriter("output.txt")
sw.Write("This is the ")
sw.WriteLine("first line of the file.")
sw.Write("The date is: ")

If you opened the output file in a text editor, it would look like this:

This is the first line of the file.
The date is: April 24, 2006
