MySqlDataReader.GetStream() throws IndexOutOfRangeException

由 老子叫甜甜 提交于 2021-02-11 06:42:33

When selecting the password hash and salt from a user I need a way to convert the result back to a byte array.

I use msyql.data 8.08 and .net core to connect to mysql5.7.18 but following exception is being thrown: MySql.Data.MySqlClient.MySqlException:“The host localhost does not support SSL connections.” How to deal with it? I had the same problem today when moving from MySql.Data 7.0.7 to 8.0.8. I was able to move forward adding the "SslMode=none" in the connection string. You will endup with something like: server={0};user id={1};password={2};persistsecurityinfo=True;port={3};database={4};SslMode=none (replacing the values with your database details) And if you using a connection pool class, then
