c＃无法连接到任何指定的MySQL主机

Question

I am trying to connect MySQL database on remote host htttp://www.tasiheel.com .

This is my code

try
    {
     string addClientQuery = "insert into clients values(null,@name,@sender,@user,@pass,@date)";
     MySqlConnection conn = new MySqlConnection("Server=http://tasiheel.com;Database=xxxxxx;Uid=xxxx;Pwd=xxxxx;");

     MySqlCommand addClientCmd = new MySqlCommand(addClientQuery, conn);
     addClientCmd.Parameters.AddWithValue("name", clinetNameTXT.Text);
     addClientCmd.Parameters.AddWithValue("sender", senderNameTXT.Text);

     addClientCmd.Parameters.AddWithValue("user", userNameTXT.Text);
     addClientCmd.Parameters.AddWithValue("pass", userPassTXT.Text);
     addClientCmd.Parameters.AddWithValue("date", DateTime.Now);
     conn.Open();
     addClientCmd.ExecuteNonQuery();
     RadMessageBox.Show("تم اضافة البيانات بنجاح");
     }
 catch (MySqlException ex)
     {
     MessageBox.Show(ex.Message);
     }

but I got the following error when trying to open connection

Unable to connect to any of the specified MySQL hosts

I can access the databse form php page on the server, but I can't from c# winform

I have enabled the remote database access by adding % to database privileges.

Any help for this?

Thanks

Answer 1

Try to change your connection string:

From:

Server=http://tasiheel.com;Database=xxxxxx;Uid=xxxx;Pwd=xxxxx;

To

Server=http://tasiheel.com;Port=3306;Database=xxxxxx;User ID=xxxx;Password=xxxxx;

Answer 2

Try to enter the IP of the remote server in the connectionstring as described in another answer.

Make sure your MySQL (where it has installed) allow remote connection. If database is on same server as code, you should better use localhost as Server (this will also save round trip to own server)
