❔ Check if Type is static

This question is probably vague as shit, but I always do this check to ensure a type is static:

private bool IsStatic(Type type)
{
  return type.IsAbstract && type.IsSealed;
}

private bool IsStatic(Type type)
{
  return type.IsAbstract && type.IsSealed;
}

So, this works because static classes are declared abstract and sealed at the IL level. My question is if this is actually valid and won't fail, ever. C# doesn't exactly have a isStatic field or something.

This should be fine (I think), because all static classses are "sealed abstract"
