直接上程式碼： using System; using System.Windows.Forms; namespace EmbedAutoCAD { public partial class MainForm : Form { public MainForm() { InitializeComponent(); }

private void browseButton_Click(
  object sender, EventArgs e)
{
  OpenFileDialog dlg =
    new OpenFileDialog();
  dlg.InitialDirectory =
    System.Environment.CurrentDirectory;

  dlg.Filter = 
    "DWG files (*.dwg)|*.dwg|All files (*.*)|*.*";

  Cursor oc = Cursor;

  String fn = "";

  if (dlg.ShowDialog() ==
    DialogResult.OK)
  {
    Cursor = Cursors.WaitCursor;
    fn = dlg.FileName;
    Refresh();
  }
  if (fn != "")
    this.drawingPath.Text = fn;

  Cursor = oc;
}
private void loadButton_Click(
  object sender, EventArgs e)
{
  if (System.IO.File.Exists(drawingPath.Text))
    axAcCtrl1.Src = drawingPath.Text;
  else
    MessageBox.Show("File does not exist");
}

private void postButton_Click(
  object sender, EventArgs e)
{

}
