MySqlConnection链接mysql

 mysql默认编码

default-character-set = utf8mb4

 

导致

MySqlConnection connection = new MySqlConnection()

connection.ConnectionString = configFile["ConnectionStrings:WeiCloudDBQRTZ"];
connection.Open();//提示错误：Guid should contain 32 digits with 4 dashes

 

可以在在连接字符串中添加 OldGuids=true; 尝试解决一下：完整连接：

修改链接串：server=;uid=root;pwd=;port=3308;database=WeiCloudDB.QRTZ;charset=utf8mb4;Character Set=utf8mb4;OldGuids=true
