vb.net 4.0中字典的求和整数值字段

Question

在.net 4.0字典中我知道我可以像这样计算所有整数值字段的总和:

 Dim dbar As Dictionary(Of String, Integer) = New Dictionary(Of String, Integer)() From {{"A", 1}, {"B", 1}, {"C", 1}}
    Dim sum As Integer = 0
    For Each v As Integer In dbar.Values
      sum += v
    Next

是否存在更优雅的方式来计算总和？

Answer 1

只需使用Sum()方法:

dbar.Values.Sum()
