In order to invoke the WriteAsync method, the method call needs to be within an async method. FileIO - to be used with Windows 8. In any case, explicitly closing the files can be considered as a good practice.

This completes sending a binary file via cURL. If the path you provide to the WriteAllText method already exists, the file will be overwritten. It is called file-handle. The form could be as simple as this: In this case we use this short-circuit feature to write the expression.

Usually you login to the API once during a transaction, then use a token for all subsequent requests. The open function gets 3 parameters. Lots of Perl programs deal with text files such as configuration files or log files, so in order to make our knowledge useful it is important at an early stage to learn about file handling.

The script goes on to the next line. Here is how I did that: Because the StreamWriter object is declared and instantiated in a using statement, the Dispose method is invoked which automatically flushes and closes the stream.

Strictly speaking this is not required in Perl. Example The following example shows how to synchronously write text to a new file using the StreamWriter class, one line at a time. I want to touch on the function on line Then the right side of the or is also executed.

As you know from the previous part of the tutorial, the "or" short-circuits in Perl as in many other languages.

Perl will automatically and properly close all the file-handles when the variable goes out of scope, at the latest when the script ends. For this reason, the samples perform minimal error checking and exception handling, if any. If the open is successful then it returns TRUE and thus the right part never gets executed.
