主题：如何把列值改成数组

 Dim str As String = e.form.Controls("ComboBox1").text
Dim a As Table = Tables("授权")
For i As Integer = 0 To a.Rows.count - 1
    Dim nr As Row = a.Rows(i)
    Dim Names As New List(Of String)
    Dim nms1() As String = nr("用户").split(",")
    'MessageBox.Show(Names)
    Names.AddRange(nms1)
    If Names.Contains(str) = False Then
        Names.Add(str)
        Else
          Names.Remove(str)
    End If
Next
我想把列值变成数组，再运用数组进行判断是否包含某个字符，再进行增删

下面句出问题了

Dim nms1() As String = nr("用户").split(",")
