c# - 如何在asp.net中使用mysql连接远程数据库？

Question

protected void Button1_Click(object sender, EventArgs e)
{
    try
    {
        string MyConString = "SERVER=http://10.54.3.208:8080/Ager/person;" + "DATABASE=agero;" + "UID=root;" + "PASSWORD=root;";
        MySqlConnection con = new MySqlConnection(MyConString);
        //MySqlConnection command = con.CreateCommand();
        con.Open();
        string s = "select * from boopathi where STU_ID =@sid and STU_PWD =@pwd";
        MySqlCommand cmd = new MySqlCommand(s, con);
        cmd.Parameters.AddWithValue("@sid", TextBox1.Text.ToString());
        cmd.Parameters.AddWithValue("@pwd", TextBox2.Text.ToString());
        cmd.ExecuteNonQuery();
        MySqlDataReader dr = cmd.ExecuteReader();
        while (dr.Read())
        {
            if (dr.HasRows == true)
            {
                Server.Transfer("WebForm1.aspx");
            }
        }      
        //close connection
        con.Close();

    }
    catch (Exception ex)
    {
        Response.Write("An error occured: " + ex.Message);
    }
}

在本地主机中它工作得很好。一旦我设置了远程链接而不是本地主机。它不再连接了。我收到类似无法连接到任何指定的 MySQL 主机的异常。

尝试一下:-

MySqlConnection c = new MySqlConnection("server=10.54.3.208; database=agero; uid=root; pwd=root");

或

string MyConString = "SERVER=10.54.3.208;" + "DATABASE=agero;" + "UID=root;" + "Pwd=root;";
