I have two lists.

List<string> listString;
List<int> listInt;

The input I get in is 

List<object>

At runtime, is there a way to convert 

List<object>

to another List?

Edit: My question is how do I it at runtime. Not compile time.

    Yes there is, but it of course depends on what exactly you want to do. What does your input contain? strings? binary data? ints? I mean, _how_ do you want to convert the `object` into an `int` or `string`? – René Vogt May 15 '19 at 17:17

List<string> listString = listObject.Cast<string>().ToList();
List<int> listInt = listObject.Cast<int>().ToList();

Try using the .OfType() filter to get the specific lists.

var all = new List<object>();
// add stuff

List<string> text = all.OfType<string>().ToList();
List<int> vals = all.OfType<int>().ToList();
