Save file - xmlSerializer

I'm creating a method to serialize a file using this code:

        public void Save(Object file, Type type, String path)
    {
        // Create a new Serializer
        XmlSerializer serializer = new XmlSerializer(typeof(type));

        // Create a new StreamWriter
        StreamWriter writer = new StreamWriter(@path);

        // Serialize the file
        serializer.Serialize(writer, file);

        // Close the writer
        writer.Close();
    }

But Visual Studio tells me this when I attempt to build: "Error 1 The type or namespace name 'type' could not be found (are you missing a using directive or an assembly reference?) c:\users\erik\documents\visual studio 2013\Projects\FileSerializer\FileSerializer\Class1.cs 16 65 FileSerializer "

Why is this?

Thanks! Erik
