主题：SQL语句

Dim T As String =e.form.Controls("DateTimePicker2").Value

Dim cmd2 As New SQLCommand

Dim dt2 As DataTable

Dim cmb2 As WinForm.CheckedComboBox

cmd2.C

cmd2.CommandText = "SELECT DISTINCT 收件人 From {快递管理} Where [邮寄日期] =  #" & T & "#"

dt2 = cmd2.ExecuteReader()

cmb2 = e.Form.Controls("CheckedComboBox3")

cmb2.ComboList= dt2.GetComboListString("收件人")

这段代码有什么问题,我根据日期提取收件人,但是提取不到?
