包含字典的值（字符串，项目）

Question

如何知道具有多个值的字典是否包含特定值？

'Create dictionary
Dim testDictionary As New Dictionary(Of String, Items)

'Code to fill dictionary
'.......................
'.......................
'.......................

'Test if a specific value is contained in dictionary
Dim testValue as String = "TEST"
testDictionary.ContainsValue(testValue) 'This doesn't work

Public Class Items
    Public Property Property1 As String
    Public Property Property2 As String
    Public Sub New()
    End Sub
End Class
