vb.net - 如何在 VB.NET 中初始化 Dictionary(Of String, HashSet(Of String))？

Question

我有一个现有的String和HashSet(Of String)，但是下面的代码

Dim myDict As New Dictionary(Of String, HashSet(Of String))(myString, myHashSet)

产生此 Intellisense 错误:Argument matching parameter 'comparer' narrows from 'System.Collections.Generic.HashSet(Of String)' to 'System.Collections.Generic.IEqualityComparer(Of String)'

创建这个字典的正确方法是什么？

Answer 1

您可以使用 Collection Initializer :

Dim myDict As New Dictionary(Of String, HashSet(Of String)) From 
       {{myString, myHashSet}}
