加载的程序集是DEBUG还是RELEASE？

Question

How can I find out if a loaded assembly is a DEBUG or RELEASE version?

Yes, I could use a method like this:

public static bool IsDebugVersion() {
#if DEBUG
    return true;
#else
    return false;
#endif
}

But this is only usable in my own code. I need a check at runtime (for third-party assemblies), like this:

public static bool IsDebugVersion(Assembly assembly) {
    ???
}

Use Assembly.GetCustomAttributes(bool) to get a list of attributes, then look for DebuggableAttribute , and then if that was found, see if the property IsJITTrackingEnabled is set to true :

public static bool IsAssemblyDebugBuild(Assembly assembly)
{
    foreach (var attribute in assembly.GetCustomAttributes(false))
    {
        var debuggableAttribute = attribute as DebuggableAttribute;
        if(debuggableAttribute != null)
        {
            return debuggableAttribute.IsJITTrackingEnabled;
        }
    }
    return false;
}

The above taken from here .

Alternative using LINQ:

public static bool IsAssemblyDebugBuild(Assembly assembly)
{
    return assembly.GetCustomAttributes(false)
        .OfType<DebuggableAttribute>()
        .Any(i => i.IsJITTrackingEnabled);
}
