How do I tell programatically if I am running under Medium Trust?

Question

In C# how do I tell if my assembly is running under medium trust in asp.net? Is there something similar to Debugger.IsAttached for this?

Answer 1

This should do the trick:

Get current ASP.NET Trust Level programmatically

Answer 2

From dmitryr's blog 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;
}

Or you can use this slightly shorter version

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;
}
