Question

我想从我的asp页面连接到mysql数据库。所以根据我的托管服务提供商告诉我使用连接字符串，其中服务器被指定为“localhost：3309”

Dim myConnection As MySqlConnection = New MySqlConnection("server=localhost:3309; user id=TID; password=TPWD; database=TDB; pooling=false;")

Dim strSQL As String = "SELECT * from Device_Data"

Dim myDataAdapter As MySqlDataAdapter = New MySqlDataAdapter(strSQL, myConnection)
Dim myDataSet As DataSet = New DataSet()
myDataAdapter.Fill(myDataSet, "Device_Data")

MySQLDataGrid.DataSource = myDataSet
MySQLDataGrid.DataBind()

但是当我运行此页面时出现此错误

[SocketException (0x2af9): No such host is known]

这是服务器问题吗？如果是，那么他们应该怎么做才能解决这个问题呢？当与服务器人员联系时，他们说这是我的编码问题..他们是对的吗？

Answer 1

MySQL ADO.NET Connector的

The correct connection string是

Server=localhost;Port=3309;Database=Test;Uid=username;Pwd=password;

Answer 2

尝试server=localhost; port=3309

SocketException：没有这样的主机
