以編程方式獲取當前ASP.NET信任級別

Question

是否有獲取當前ASP.NET信任級別的API？

Answer 1

從dmitryr's blog：

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; 
} 

Answer 2

下面的代碼獲取當前ASP.NET信任級別編程方式使用官方配置API：

using System.Web; 
using System.Web.Configuration; 

... 

var trust = WebConfigurationManager.GetSection("system.web/trust") as TrustSection; 
return trust.Level;
