Writing Files

For writing text in a file we create a StreamWriter object with the path of the file, similar to how we create a StreamReader object.

Note

The platform currently doesn't support file writing so this can be practiced on a compiler on your PC.

The StreamWriter object offers a WriteLine method which can write text into a file. We will now try to write something to the text.txt file.

The above code will overwrite the previous content of the text.txt file and replace it with:

StreamWriter has a second parameter called "append" which takes in a boolean value and is set to false by default. If we set the append parameter to true then the code will not overwrite the older text rather it would append the new text to the end of the file.

For-example, consider the file text.txt has the following text in it:

We will use the following code to add a new line to it:

The file will look like this after running the code:
