    {
        {0, "string"},

推荐答案

如果使用Visual Studio 2010或更高版本，则应使用 FROM 关键字像这样：

If using Visual Studio 2010 or later you should use the FROM keyword like this:

Dim days = New Dictionary(Of Integer, String) From {{0, "string"}, {1, "string2"}}

如果您需要使用Visual Studio的早期版本，并且需要经常执行此操作，

If you need to use a prior version of Visual Studio and you need to do this frequently you could just inherit from the Dictionary class and implement it yourself.

它可能看起来像这样：

Public Class InitializableDictionary
    Inherits Dictionary(Of Int32, String)

    Public Sub New(ByVal args() As KeyValuePair(Of Int32, String))
        MyBase.New()
        For Each kvp As KeyValuePair(Of Int32, String) In args
            Me.Add(kvp.Key, kvp.Value)
        Next
    End Sub

End Class
