如何以編程方式告訴我是否在Medium Trust下運行？

Question

在C＃中，如何判斷我的程序集是否在asp.net中的中等信任下運行？是否有類似於Debugger.IsAttached爲此？

Answer 1

這應該做的伎倆：

Get current ASP.NET Trust Level programmatically

Answer 2

從dmitryr的博客post：

public static AspNetHostingPermissionLevel GetTrustLevel() 
{ 
    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; 
}

或者您可以使用此略短版

public AspNetHostingPermissionLevel GetCurrentTrustLevel() 
{ 
    foreach (AspNetHostingPermissionLevel trustLevel in Enum.GetValues(typeof(AspNetHostingPermissionLevel))) 
    { 
     try 
     { 
      new AspNetHostingPermission(trustLevel).Demand(); 
     } 
     catch (System.Security.SecurityException) 
     { 
      continue; 
     } 
     return trustLevel; 
    } 
    return AspNetHostingPermissionLevel.None; 
}
