from a list. They are basically dictionaries of data. The main methods are:
duction to .NET
Intro
Add(object,object)
Clear()
Clone()
Contains(object)
ContainsValue(object)
CopyTo(System.Array,int)
GetEnumerator()
GetHash(object)
Hashtable(int)
Hashtable()
KeyEquals(object,object)
Remove(object)
And the main properties are:
Count
Adds elements with a specified key and value into the
Hashtable.
Removes the elements in Hashtable.
Creates a shallow copy of the Hashtable.
Determines whether the Hashtable contains a certain key.
Determines whether the Hashtable contains a certain value.
Copies a parts of a Hashtable to a one‐dimensional Array
instance.
Returns an enumerator value that can iterate through the
Hashtable.
Returns the hash code for the specified key.
Create a empty Hashtable.
Creates an empty Hashtable.
Compares an object with the key.
Removes the element with the specified key from the

Gets the number of key‐pairs in the HashTable.
