Hashtable with multiple values for single key

Question

I want to store multiple values in single key like:

HashTable obj = new HashTable();
obj.Add(\"1\", \"test\");
obj.Add(\"1\", \"Test1\");

Right

Answer 1

That throws an error because you're adding the same key twice. Try using a Dictionary instead of a HashTable.

Dictionary> values = new Dictionary>();
IList list = new List()
{
    "test", "Test1"
};
values.Add(1, list);
