错误:已有打开的与此 Command 相关联的 DataReader,必须首先将它关闭

原代码:

public void UpdatePermissionUserTypeByRightID(int rightID, string userTypes)
        {
            var targetList = ListAll().Where(s => s.rightID == rightID);

            foreach (var item in targetList)
            {
                item.permissionUserType = userTypes;
                //注意,如果子节点可见,则父节点一定可见
                //修改父节点权限,如果有父节点的话,注意要避免父节点中的角色ID重复
                if (item.parentID > 0)
                {
                    MenuNodes parent1 = getByID(item.parentID);
                    string tempPUserTypes = JimShared.GetNoOverlapStr(item.permissionUserType, parent1.permissionUserType);
                    parent1.permissionUserType = tempPUserTypes;                    
                }                
            }
            //!提交数据
            commit();
        }

修改后:(只是加了一个tolist())

public void UpdatePermissionUserTypeByRightID(int rightID, string userTypes)
        {
            var targetList = ListAll().Where(s => s.rightID == rightID).ToList();

            foreach (var item in targetList)
            {
                item.permissionUserType = userTypes;
                //注意,如果子节点可见,则父节点一定可见
                //修改父节点权限,如果有父节点的话,注意要避免父节点中的角色ID重复
                if (item.parentID > 0)
                {
                    MenuNodes parent1 = getByID(item.parentID);
                    string tempPUserTypes = JimShared.GetNoOverlapStr(item.permissionUserType, parent1.permissionUserType);
                    parent1.permissionUserType = tempPUserTypes;                    
                }                
            }
            //!提交数据
            commit();
        }
