推荐答案

一些示例code：

  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);
    }
  }
