Summary

An implementation of HashSet class in .NET that can be used in .NET Compact Framework (.NET CF), in which it is natively missing

Key Features

• Parameterizable HashSet(Of T) implementation
• Modeled after the Java SE java.util.HashSet class

Usage

Examples of basic usage of a HashSet(Of String):

1. Initialize a HashSet(Of String):

   Dim strHs = New HashSet(Of String)
   Assert.AreEqual(strHs.Count, 0)
   

2. Add an element:

   Dim strHs = New HashSet(Of String)
   strHs.Add("first")
   Assert.IsTrue(strHs.Contains("first"))
   

3. Remove an element:

   Dim strHs = New HashSet(Of String)
   strHs.Add("first")
   strHs.Remove("first")
   Assert.IsFalse(strHs.Contains("first"))
   

4. Clear elements:

   Dim strHs = New HashSet(Of String)
   strHs.Add("first")
   strHs.Add("second")
   strHs.Add("third")
   Assert.AreEqual(strHs.Count, 3)
   strHs.Clear()
   Assert.AreEqual(strHs.Count, 0)
   

5. Compare HashSets

   Dim strHs1 = New HashSet(Of String)
   strHs1.Add("first")
   strHs1.Add("second")
   strHs1.Add("third")
   Dim strHs2 = New HashSet(Of String)(strHs1)
   Assert.IsTrue(strHs1 = strHs2)
   strHs2.Remove("second")
   Assert.IsTrue(strHs1 <> strHs2)
   

How to Build

This library and associated unit tests were developed in VS 2008 as Smart Device projects.
