Lalit M · Answer

how to use a Hashtable in C#. Creating a Hashtable The Hashtable class in C# represents a hashtable. The following code creates a Hashtable: private Hashtable hshTable = new Hashtable(); Adding Items to a Hashtable Add method of Hashtable is used to add items to the hashtable. The method has index and value parameters. The following code adds three items to hashtable. hshTable .Add("Author1", "Mahesh Chand"); hshTable .Add("Author2", "James Brand"); hshTable .Add("Author3", "Mike Gold"); Retrieving an Item Value from Hashtable The following code returns the value of "Author1" key: string name = hshTable["Author1"].ToString(); Removing Items from a Hashtable The Remove method removes an item from a Hashtable. The following code removes item with index "Author1" from the hashtable: hshTable.Remove("Author1"); Looking through all Items of a Hashtable The following code loops through all items of a hashtable and reads the values. // Loop through all items of a Hashtable IDictionaryEnumerator en = hshTable.GetEnumerator(); while (en.MoveNext()) { string str = en.Value.ToString(); } more information you will get from this link Understanding HashTable Basic Laval
