Dim array1() As String

  For i = 0 To lstOne.Items.Count - 1
  array1(i) = lstOne.Items(i).ToString
  Next

变量"array1"在赋值前被使用.可能会在运行时导致空引用异常


要怎么解决呢?

------解决方案--------------------

VB.NET code

        Dim array1() As String
        Dim i As Integer = 0
        ReDim array1(lstOne.Items.Count)

        For i = 0 To lstOne.Items.Count - 1
            array1(i) = lstOne.Items(i).ToString
        Next
