如何在我的 C# 應用程式中實作拖放檔案功能？

public partial class Form1 : Form {
    public Form1() {
        InitializeComponent();
        this.AllowDrop = true;
        this.DragEnter += new DragEventHandler(Form1_DragEnter);
        this.DragDrop += new DragEventHandler(Form1_DragDrop);
    }

    void Form1_DragEnter(object sender, DragEventArgs e) {
        if (e.Data.GetDataPresent(DataFormats.FileDrop)) e.Effect = DragDropEffects.Copy;
    }

    void Form1_DragDrop(object sender, DragEventArgs e) {
        string[] files = (string[])e.Data.GetData(DataFormats.FileDrop);
        foreach (string file in files) Console.WriteLine(file);
    }
}
