杭州交通信息网欧标德语等级考试:asp.net连接数据库，急用！
来源：百度文库 编辑：杭州交通信息网 时间：2024/05/03 05:26:57
每次在连接数据库时运行到 conn.open() 就停下来了．
连接数据库的语句是：
Dim conn As New SqlClient.SqlConnection
Dim cmd As New SqlClient.SqlCommand
cmd.Connection = conn
……
conn.ConnectionString = ConfigurationSettings.AppSettings("DSN_teacher")
……
cmd.CommandText = "select * from teacher_login where t_id ='" + TextBox1.Text + "'"
Try
conn.Open()
Dim reader As IDataReader
reader = cmd.ExecuteReader()
……
其中"DSN_teacher"是<add key="DSN_teacher" value="server=localhost; uid=teacher_access; pwd=8241; database=network_course"/>
没有报错，每次运行到conn.Open(),等一会儿后，就跳到catch了。拜托高人指点。
