iterate through a hashtable with multiple values

I have a hashtable with 7 keys, and each key contains an array list.

How do I go about iterating through all the values for each key? Thanks.

I was able to figure it out by using dictionary instead of hashtable if anyone else has a similar question

Dictionary<string, ArrayList> dictionary = new Dictionary<string, ArrayList>();

for (int i = 0; i < dictionary["Test"].Count; i++)
{
foreach (KeyValuePair<string, ArrayList> item in dictionary)
{
if (item.Key == "Test")
{
MessageBox.Show(item.Value[i].ToString());
}
}
}
