Connection String for MySQL in C#.Net2.0
-
I am not able to connect to a remote MySQL server on C#.Net. The server is not accepting the request of opening the database. :( I think the connection string is going somewhere wrong: <add key="ConnectionString" value="SERVER =IP add; HOST=localhost; PORT=portNo; DATABASE=dbname; UID=userId; PASSWORD=pass;Connection Lifetime=0;"/> I dont know where im going wrong. Please correct me if someone knows the correct string to connect to a MySQL db thru C#.Net2.0 Thanks

Show us the code fragment you are using to access the connection string, and the code fragment you use to open the connection to the DB. (Not the whole program, please, just the relevant bits)
Real men don't use instructions. They are only the manufacturers opinion on how to put the thing together.

Connection Terminated unexpectedly. I would like to add here that now I have installed a local MySQL Server and restored one of the table to fetch data form it. But still I am not able to connect to the database locally also from C#.Net2.0 :(. When the code reaches to mySQLCon.open(), then it fires the above exception. Connection String:"Server=localhost; PORT=80; Data Source=ecampust_opensis; User Id=root; Password=;" Thanks

Now the exception is coming as: {MySql.Data.MySqlClient.MySqlException: Unable to connect to any of the specified MySQL hosts ---> System.Net.Sockets.SocketException: The requested name is valid and was found in the database, but it does not have the correct associated data being resolved for

Check your database server: Do you have the Named Pipes protocol enabled in the Network setup? (apparently .NET Sockets likes both Named Pipes and TCP/IP) Also check your firewall at the server - it may be rejecting port 80.

My guess is that you have the wrong port number. Port 80 is normally reserved for HTTP traffic (web browsers/servers).

Hey dear Griff, I would like to ask you here that "As MySQL is open source and there are many articles for connecting the .Net application with MySQL db, and no where I have found that someone have specified this Named Pipes protocol thing in order to connect to MySQL dB although I have checked firewall. As our client is the owner of the MySQL Database, I think some dB level permission is to be granted in order to access the dB remotely. What do you say dear Griff on this? Thanks

Dave KreskowiakHey Dave, I am checking the connection locally, so i think the port must be 80 (for all local servers).

The port number has nothing to do with the server being local or not.

"Thinking" is not allowed in this business. You either know what the port is, or you have to find out.

Hey dear Griff, the error is coming as "Connection unexpectedly terminated". I am just going sick over this issue :(. Kindly help someone.
