How to get list string from Hashtable?

I don’t how to get list values

Hashtable hshTable = new Hashtable();
List<string> l= new List<string>();
l.Add("string1");
l.Add("string2");
hshTable.Add("1",l);

try

string temp= hshTable["1"][0];

error Cannot apply indexing with [] to an expression of type ‘object’

>Solution :

From the documentation and error message, Hashtable.Item[Object] returns object.

public virtual object? this[object key] { get; set; }

You should cast the value as List<string> type before getting the value by index.

string temp= ((List<string>)hshTable["1"])[0];
