如何循环得到Dictionary的key值

怎么循环得到Dictionary的key值?

VB code

Dim dic As New Dictionary(Of String, String)dic.Add("111", "")dic.Add("32", "")

  我现在要把这两个key值放到textbox1中去,key之间用vbcrlf分开 要怎么写呢?(是要key值不是item的值.)

  我这样写它报错:No default member found for type 'KeyCollection'.
一定要先另外弄个数组k才能把key取出来吗?这么麻烦?

VB.NET code

  Dim k        k = dic3.Keys        For i = 0 To dic3.Count - 1            TextBox1.Text = TextBox1.Text + k(i)+vbcrlf        Next

谢谢!!


[解决办法]

VB code

Dim dic As New Dictionary(Of String, String)        dic.Add("111", "")        dic.Add("32", "")        For Each k In dic.Keys            ...        Next
