Sorting A HashTable Object Using LINQ In C#.NET And VB.NET
In .NET, you can't directly sort a Hashtable object. A tip on sorting a Hashtable object is to cast it to Dictionary then apply LINQ OrderBy() method to the Hashtable object. See examples below: VB.NET 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 Private Sub SortHashTableKey () hash = New Hashtable() hash.Add( "B" , 1 ) hash.Add( "A" , 2 ) hash.Add( "C" , 3 ) Dim dict = hash.Cast( Of DictionaryEntry)() _ .ToDictionary(Function(d) d.Key, Function(d) d.Value) _ .OrderBy(Function(e) e.Key) Console.WriteLine( "Sort by Key" ) For Each item In dict.ToList() Console.WriteLine( String .Format( "{0}, {1}" , item.Key, item.Value)) Next Console.WriteLine(Environment.NewLine) End Sub Private Sub SortHashTableValue () ...
