Here’s how to count repeated words in a List<string>

    {
        "Jane", "Bandy", "Ram", "Jane", "Bandy", "Carol", "Bandy"
    };

    // Count Repeated Words
    var q = strList.GroupBy(x => x)
       .Select(g => new { Value = g.Key, Count = g.Count() })
       .OrderByDescending(x => x.Count);

    foreach (var x in q)
    {
        Console.WriteLine("Value: " + x.Value + " Count: " + x.Count);
    }
}

VB.NET

Shared Sub Main(ByVal args() As String)
    Dim strList As New List(Of String)() From {"Jane", "Bandy", "Ram", _
"Jane", "Bandy", "Carol", "Bandy"}

    ' Count Repeated Words
    Dim q = strList.GroupBy(Function(x) x).Select(Function(g) New _
With {Key .Value = g.Key, Key .Count = g.Count()}) _
.OrderByDescending(Function(x) x.Count)

    For Each x In q
        Console.WriteLine("Value: " & x.Value & " Count: " & x.Count)
    Next x
End Sub
