Sending a file as an argument to a method?

Question

Is it possible:

public static void DoThis(file aFile){
    //Blah blah blah
}

Answer 1

It depends on what you need to do :)

Options include:

• path (string)
• contents (string or byte [])
• some kind of complex object model (of your choice) of content
• Fileinfo
• FileStream (or just a stream)
• some reader / writer; TextReader, XmlWriter, etc.

Answer 2

That's right. If you have a link to a file in the calling method, you can do this.

Answer 3

, . ....

public static void DoThis(file aFile)
{
    if ( aFile == null ) { // report error or whatever }
    //Blah blah blah
}
