MySqlConnection鏈接mysql

 mysql默認編碼

default-character-set = utf8mb4

 

導致

MySqlConnection connection = new MySqlConnection()

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

 

可以在在連接字符串中添加 OldGuids=true; 嘗試解決一下：完整連接：

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