Casting a list of a primitive type to a IEnumerable<object>

Question

in my C# program, I need to cast an object to a IEnumerable<object>. All I know about that object is, that it is a list (Type.IsGenericType):

IEnumerable<object> iEnu = myObject as IEnumerable<object>;

if (iEnu != null)
  foreach (object o in iEnu)
    // do stuff

As long as the type of the list is not a primitiv, it works fine, as all classes inherit from object. But primitives doesn't. Therefore, the cast to IEnumerable<object> returns null. I'd need to cast to IEnumerable<int>, if it's a list of integer, to IEnumerable<bool> if it's a list of booleans and so on. Naturally, i want just one generic cast.

Any idea, what to do to get the primitive lists as well?

只需使用IEnumerable代替IEnumerable<object>; 虽然int[]没有实现IEnumerable<object>，但它确实实现了IEnumerable：

IEnumerable enumerable = myObject as IEnumerable;

if (enumerable != null)
{
    foreach (object o in enumerable)
    {
        // do stuff
    }
}
