问题描述

限时删除！！

我想确保我的ASP.Net库将在中等信任的工作。我有问题，但是，在我需要禁用位code，如果它正处于中级信任运行。

I am trying to make sure my ASP.Net library will work under Medium Trust. I'm having problems however in that I need to disable a bit of code if it is being run under medium trust.

我如何从C＃确定？

下面本文介绍一种机制来确定的信任级别：

This article here describes a mechanism to determine the trust level:

找出在ASP.NET 当前信任级别

下面是code以防万一死链接：

Here is the code just in case the link dies:

AspNetHostingPermissionLevel GetCurrentTrustLevel() {
  foreach (AspNetHostingPermissionLevel trustLevel in
      new AspNetHostingPermissionLevel [] {
        AspNetHostingPermissionLevel.Unrestricted,
        AspNetHostingPermissionLevel.High,
        AspNetHostingPermissionLevel.Medium,
        AspNetHostingPermissionLevel.Low,
        AspNetHostingPermissionLevel.Minimal
      } ) {
    try {
      new AspNetHostingPermission(trustLevel).Demand();
    }
    catch (System.Security.SecurityException ) {
      continue;
    }

    return trustLevel;
   }

   return AspNetHostingPermissionLevel.None;
}

我只是测试它在ASP.NET应用程序MVC3在中，然后完全信任运行，它做什么，它在锡说。

I just tested it in an ASP.NET MVC3 application running at Medium and then Full trust and it does what it says on the tin.
