主题：如何判断外部数据源的列名称是否包括“姓名”?

没有直接的办法，迂回解决吧，用SQLCommand解决速度也不慢。

Dim cmd As New SQLCommand
Dim cmb As WinForm.ComboBox
cmd.ConnectionName  = "nwnd"
cmd.CommandText = "Select * From {表名} Where [主键] Is Null "
Dim dt As DataTable = cmd.ExecuteReader()
For Each dc As DataCol In dt.DataCols
    If dc.Name.Contains("姓名") Then
        MessageBox.Show("有姓名列")
    End If
Next
