解决方案

昏暗sc1_currentmanuf的String = CTYPE（dlContacts.Items（0）.FindControl（selCurrentManuf），DropDownList的）。文本    昏暗更改为MyQuery作为字符串=SELECT * FROM c5_model，其中c5_manufid =+ sc1_currentmanuf

Dim sc1_currentmanuf As String = CType(dlContacts.Items(0).FindControl("selCurrentManuf"), DropDownList).Text Dim myQuery As String = "SELECT * FROM c5_model where c5_manufid = " + sc1_currentmanuf
