小弟在写程序报如下异常错误，求高人指导
An error occurred while executing the command definition.See the inner exception for details .System,InvalidOperationException:The transaction associated with the current connection has completed but has not been disposed.The transaction must be disposed before the connection can be used to execute SQL statements
问题补充：
与当前连接相关联的事物已经完成，但尚未尚释放。必须先释放该事物，然后才能使用该连接来执行SQL语句。
