У меня ошибка с моим кодом C # и MySQL.
Можете ли вы помочь мне решить это, пожалуйста?
Вот мой код:
try
{
using (MySqlConnection dbcon = new MySqlConnection(SQLConnectionString))
{
dbcon.Open(); // ERROR HERE
string sql = "SELECT * FROM scp_patreons";
MySqlCommand command = new MySqlCommand();
command = dbcon.CreateCommand();
command.CommandText = sql;
using (MySqlDataReader dr = command.ExecuteReader())
{
while (dr.Read())
{
string fullname = (string)dr["fullname"];
plugin.Info("Name: " + fullname + "");
}
}
}
}
catch (Exception ex)
{
plugin.Info("SQL_ERROR: " + ex.Message + "\n" + ex.StackTrace);
}
string SQLConnectionString = "Server=*; Database=*; User ID = *; Password=*; Pooling=false;SslMode=None;";
и я получаю сообщение об ошибке:
SQL_ERROR: The type initializer for 'MySql.Data.MySqlClient.MySqlConnectAttrs' threw an exception.
