Question

Trying to write a simple C# script to copy file to directory one level up. Here is what I have, but it is sending an error,

“Script.OnActivate()” not all code paths return a value.

and my code:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Drawing;
using System.Text;
using System.Text.RegularExpressions;
using System.IO;
using System.Windows.Forms;
using System.Globalization;

    class Script : CopyFile {

        public static bool OnActivate() {
            CopyDataFile("script/file.js", "../file.js");
        }

    }

SOLVED!

using System;
using System.IO;

class Script : CopyFile {

    public static void OnActivate() {
        FileInfo myFile = new FileInfo("script/file.js"); 
        myFile.CopyTo(myFile.Directory.Parent.FullName + "\\" + myFile.Name); 
    }

}

This moves file.js into the directory one level up from “script/”

Answer 1

The error occurs because you do not return a bool

   public static bool OnActivate() {
        CopyDataFile("script/file.js", "../file.js");
        return true;
    }

If you dont want to return something change you method to return void, do the following

   public static void OnActivate() {
        CopyDataFile("script/file.js", "../file.js");
    }

MSDN The void operator evaluates its expression, and returns undefined. It is most useful in situations where you want an expression evaluated but do not want the results visible to the remainder of the script.
