由于异常，无法从C＃应用程序访问MySQL：“拒绝访问用户'root'@'localhost'（使用密码：YES）”

Question

I am making a simple application and while connecting it to the MySQL Database I have running using WAMP Server, it is throwing an exception and can't connect.

An unhandled exception of type 'MySql.Data.MySqlClient.MySqlException' occurred in MySql.Data.dll

Additional information: Authentication to host 'localhost' for user 'root' using method 'mysql_native_password' failed with message: Access denied for user 'root'@'localhost' (using password: YES)

I have tried changing the users, database names but still nothing works.

The string I am using for establishing the connection is

string MyConnectionString = "Server=localhost;Database=testdb;Uid=root;Pwd=root1234;";

Please Help. I have a project due on Monday morning.

Answer 1

I got it now. The problem was I had installed MySQL Community version and also had MySQL in WAMP so very probably they both were causing conflicts. I uninstalled both and reinstalled WAMP. That worked.

Answer 2

You can create user in MySql

 CREATE USER 'username'@'servername' IDENTIFIED BY 'password';

or using phpmyadmin select database and create a new user or update password

If you are using wamp xamp like packs be carefull becouse if you change root password phpmyadmin would be break;

i suggest create a new user and give root previlliges to that user and NEVER USE root user in production

good luck.
