bookWriting Files

Recap

  • We can use the StreamWriter object for writing files;
  • If the file at the specified path does not exist, the StreamWriter object creates it;
  • If the file at the specified object already exists, the StreamWriter object by default overwrites it - which means that the previous content will be deleted. We will learn how to prevent that in the upcoming section;
  • StreamWriter has a WriteLine method for writing a line of text into a file. This method automatically moves the cursor to the next line after writing is done. In other words, it automatically appends a "\n" character after the text we write into the file;
  • Similar to WriteLine, there is a Write method, however, it doesn't move the cursor to the next line after writing text into a file;
  • Just like StreamReader, we also need to close the StreamWriter object either by using the Close() method or by utilizing the using statement to automatically close it after use.
