如何以编程方式告诉我是否在Medium Trust下运行？

Question

在C＃中如何判断我的程序集是否在asp.net中的中等信任下运行？是否有类似于Debugger.IsAttached的内容？

Answer 1

这应该可以解决问题：

Get current ASP.NET Trust Level programmatically

来自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;
}

或者你可以使用这个稍短的版本

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;
}
