Win 7请求获得类型'System.Security.Permissions.SecurityPermission的权限失败
我有一个dll，它从用asp.net编写的Intranet Web应用程序访问本地机器上的扫描仪。使用caspol在本地计算机上给予dll完全信任。在Win XP上一切正常，但在Win 7上没有。
代码是：
PermissionSet ps = new PermissionSet(PermissionState.Unrestricted);
ps.AddPermission(new SecurityPermission(SecurityPermissionFlag.AllFlags));
ps.Assert();
wiaDevMgr = new DeviceManager();
foreach (DeviceInfo di in wiaDevMgr.DeviceInfos) {
Exception: Acquire from WIA failed Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
