Call a function inside an event handler

Hello,

I am watching a directory so i am using system watcher and on the event handler, I would like when the event happens, to execute a function that does a specific job. How can i call a function inside the event handler or a way to say that when the event happens, go and do what is written in the following function. Thanks in Advance

static void OnChanged(object source, FileSystemEventArgs e)
{
// Specify what is done when a file is changed, created, or deleted.
Console.WriteLine("File: " + e.FullPath + " " + e.ChangeType);
SomeGlobalVariables.counter++;
SomeGlobalVariables.Range = SomeGlobalVariables.counter + 1;
Console.WriteLine("Counter is" + SomeGlobalVariables.counter + "," + "Range is" + SomeGlobalVariables.Range);
// Call function ReadData(string[,]Result)
}
static void ReadDATA(out string[,] Result)
{
// Operation
// Or should i call the event handler here?
}

You don't need to call the event handler.
Take a look at below.

you can call ReadData inside the onchanged event handler implementation making sure that it correctly prints the updated data as per your code.
