azure webjob连接到远程mssql实例。 拒绝访问

Question

Hi I want to use a web job to call the following code:

   using (SqlConnection con = new SqlConnection(ConfigStore.RemoteConnectionString()))
   {
       using (SqlCommand cmd = new SqlCommand(xxxxxx, con))
       {
           cmd.CommandType = CommandType.StoredProcedure;

           con.Open();

           SqlDataReader reader = cmd.ExecuteReader();
           if (!reader.HasRows)
           {

           }

           while (reader.Read())
           {

           }
           reader.Close();
       }
   }

Im getting the following error

How would I make sure that the azure can connect to this remote sql box?

How would I achieve this without compromising security?

Many thanks

Answer 1

This looks like an incorrect connection string. Can you debug what the ConfigStore.RemoteConnectionString() method returns and that it's a valid connection string?
