Is it possible to treat values and items of a DropDownList like a HashTable?

Is it possible to treat values and items of a DropDownList like a
HashTable?
>
My page records the value of the ConsultantName in a label
lblConsultant and the ID in a hidden field hidConsultantID
>
If I know the value of the ID: hidConsultantID, how do I lookup the
corresponding name, given that I have a DropDownList which maps
corresponding ConsultantIDs to their Names for the consultant
(ddlConsultant, IDs are values and names are shown as text)?

Must I need to loop through each item?

for (int i = 0; i < ddlConsultant.Items.Count; i++)
if (hidConsultantID.ToString() == ddlConsultant.Items[i].Value)
lblConsultantName.Text = ddlConsultant.Items[i].Text ;

Or is there an another way?
