LINQ链接数据库出错(There is already an open DataReader associated with this Command which must be closed first )
LINQ: There is already an open DataReader associated with this Command which must be closed first
在Linq to SQL和Entity Framework,使用Linq查询数据的时候会出现错误:There is already an open DataReader associated with this Command which must be closed first 。
解决方案:
在数据库连接串上添加MultipleActiveResultSets=true。
