HashTable provide a Clear() method to clear all the items.
Hashtable EmpHashTable = new EmpHashTable();
EmpHashTable.Add("Key1", "Akiii");
EmpHashTable.Add("Key2", "Sharad");
EmpHashTable.Add("Key3", "Anirban");
protected void btnClear_Click(object sender, EventArgs e)
{
EmpHashTable.Clear();
ListBoxCloths.DataSource = EmpHashTable;
ListBoxCloths.DataBind();
lblMessage.Text = "HashTable Items Cleared";
}
Thanks and Regards
