Question

I have an object which contains an array of any type (not a priory known type. So I cannot a simple cast in the code because I can determine the type just in the run-time!). How can I extract the content of array?
For example:

int[] array = new int[] { 0, 1, 2 };
object obj=array;
...
//Here I know that obj is an array (<b>of a priory unknown type and I cannot use type conversion in the code </b> 
//How can extract elements of obj and use them, e.g. write them on the screen?`

Answer 1

An array is an IEnumerable<T>, using Covariance an IEnumerable<object>. That means any array is an IEnumerable<object>.

int[] array = new int[] { 0, 1, 2 };
object obj=array;
IEnumerable<object> collection = (IEnumerable<object>)obj;

foreach (object item in collection)
{
    Console.WriteLine(item.ToString());
}
