一直对的运行环境没有搞清楚，希望高手讲解一下。
我的代码如下，编译之后用netload加载到CAD2008中，执行到打开文件的时候，老是报致命错误，然后CAD2008退出了。
[CommandMethod("CloseXP", CommandFlags.Session)]
public void StartWatch()
{
System.Windows.Forms.MessageBox.Show("测试开始", "开始监听！");
try
{
IPEndPoint e = new IPEndPoint(IPAddress.Any, 1234);
Udp = new UdpClient(e);
Udp.EnableBroadcast = true;
Udp.BeginReceive(new AsyncCallback(Udp_ER), Udp);
}
catch { }
}
[CommandMethod("CloseXP1", CommandFlags.Session)]
public static void OpenXP()
{
try
{
//此处老是报错
Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.Open(fileName);
}
catch (Autodesk.AutoCAD.Runtime.Exception ex)
{
System.Windows.Forms.MessageBox.Show(ex.Message, "打开文件出错！");
}
}
protected static string fileName;
[CommandMethod("CloseXP2",CommandFlags.Session)]
public static void Udp_ER(IAsyncResult ar)
{
byte[] msg = null;
IPEndPoint addr = null;
try
{
msg = Udp.EndReceive(ar, ref addr);
Udp.BeginReceive(new AsyncCallback(Udp_ER), null);
}
catch (System.Exception ex)
{
}
if (msg != null && msg.Length > 0)
{
//接受其他程序发送过来的网络信息，信息为：文件路径信息，绝对正确。
System.Windows.Forms.MessageBox.Show(Encoding.Default.GetString(msg), "收到信息！");
fileName = Encoding.Default.GetString(msg);
OpenXP();
}
}
