项目执行的时候出现错误

There is already an open DataReader associated with this Command which must be closed first.

可以尝试在连接字符串中，加上
MultipleActiveResultSets=true

具体的原因和方案，探究中

MySql.Data.dll Nuget更新到 6.10.4 版本的(Core 2.0只支持当前版本), 再检查连接字符串是否正确

运行后报错这个，SqlSugar.SqlSugarException:“MySql.Data.dll Nuget更新到 6.10.4 版本的(Core 2.0只支持当前版本), 再检查连接字符串是否正确，Unable to connect to any of the specified MySQL hosts.”，您好，请问下这个要怎么改下哪里啊，mysql连接字符串已经改过了

发现一个问题，今天的代码拷下来，打开“权限分配”页面，页面中获取不到数据，后端报错

如上图

版本区别

master，NETcore2.2 有什么区别吗，master 是NETCore 2.2吗

单库情况下,ISqlSugarClient未按照MainDb设置的注入,而是注入第一个。

这里配置了MainDB，没有勾选多库。

这里根据配置的MainDB，创建了表结构和种子数据。

但是报了sqlsugar的错，这里显示Sqlite，错误位置在权限认证(接口)。

跟踪到BaseRepository里，_dbBase注入的是配置文件中第一个，而且不是按MainDb设置的注入。

关闭所有菜单无效

http://123.206.33.109:2364，这个演示地址里面，点击账户侧的关闭所有操作后，界面是关闭了，但是点击刷新又会全部显示出来了？

t4 模版有没有基于 mysql 的

Vschool.FrameWork T4好像不可以切换数据源，只能mssql 我想用mysql

ForEach 批量更新用户角色关系出错，已经连接打开，需要先关闭

LogAOP 异步代理的第二种方案（同时开启ids4与LogAOP后接口没有响应）

如题，调试的时候执行到AwaitTaskWithPostActionAndFinallyAndGetResult 方法的 await postAction();就直接结束了，请问怎么解决

SqlSugar 多个 dbcontext 要怎么注册实现

在日常的使用当中，有需求要连接多个数据库来操作。这时候要怎么去处理这个dbcontext呢？

后期有安排这方面的东西吗？

发现LogAop存在无法记录异常信息的问题

if (typeof(Task).IsAssignableFrom(type))
{
var resultProperty = type.GetProperty("Result");
dataIntercept += ($"【执行完成结果】：{JsonConvert.SerializeObject(resultProperty.GetValue(invocation.ReturnValue))}");
}
else
{
dataIntercept += ($"【执行完成结果】：{invocation.ReturnValue}");
}

        Parallel.For(0, 1, e =>
        {
            LogLock.OutSql2Log("AOPLog", new string[] { dataIntercept });
        });//多线程并行的for循环

方法无法执行到log记录

sqlsugar采用Oracle数据库连接时，插入操作时，本框架中主键自增时怎么处理的呢？

问下，感觉你这个框架，Services层，每个Service只能操作一个实体类，即Repository，这种在实际业务中不可能这么简单吧，一般都是几张表之间的操作，逻辑

基于AOP的Redis缓存

在数据insert或update之后，怎么把相关的Redis缓存清理掉呢

关于本项目在并发中出现数据库连接closed的问题。

【用sqlsugr有时候会报Invalid operation. The connection is closed】

【说明】：就是在异步多并发的时候，sugar实例偶尔会出现连接异常，并不是很常见，如果并发达不到一千以上，不用担心这个问题。

【更正】：有人提到这个问题，多半是自己没有更新SqlSugar 5.0.10+版本，请不要使用之前的版本，还一直压测说报错。

如果还不行
【最后的方案】
1、或者每次访问仓储中每一个方法的时候，都new一个实例，这样实例就不会丢失了。比如把BaseRepository的_db换成一个获取实例方法，每次都new一个，或者ISqlsugarclient注入改成services.AddTransient(o =>。
但是这样不利于事务提交，所以我不建议这么操作。

2、当然好像在同步中没有这个问题，想省事儿，改成同步也行。

部署到测试服务器后 POST请求的参数超过956个字符后容易报错: Reading is already in progress.

已经定位到问题所在:
Startup.cs
//记录请求与返回数据
app.UseReuestResponseLog();

如果注释后运行就不会出现上述问题

在 IPLogMildd.cs 报错行 72
导致进不到方法中

请问为何每个Repository(IUnitOfWork unitOfWork) 都要传递这个unitOfWork

XXXRepository通过反射加入容器，那这个 IUnitOfWork 肯定来源于容器依赖注入，IUnitOfWork 依赖于SqlSugarClient的ADO事务；这种传递是为何？也没见类内部使用啊。
如果想用跨方法事务，直接在构造方法注入即可，开启线程share，难道不传时，直接注入IUnitOfWork 会出问题？

Quartz 任务是否 IsStart 问题

1，当应用程序部署在iis 中，iis应用程序池有回收机制，回收之后quartz会全部停止，此时TasksQz表里的IsStart 字段将不再准确，
建议使用以下代码判断启动状态
public async Task GetJobState(TaskJobInfo model)
{
JobKey jobKey = new JobKey(model.rowId.ToString(), model.jobGroup);
var triggers = (await _scheduler.Result.GetTriggersOfJob(jobKey)).FirstOrDefault();
if (triggers != null)
{
return await _scheduler.Result.GetTriggerState(triggers.Key);
}
return TriggerState.None;
}

2，建议将task 从主程序中剥离出来，单独部署

mysql +sqlsugar 时间类型的字段 SugarColumn 设置可空 c#的时间字段不是可空类型

环境：sqlsugar+mysql
[SugarColumn(ColumnName = "approval_time", ColumnDescription = "审核时间"**,IsNullable =true**)] public DateTime approval_time { get; set; }
加上特性IsNullable =true 但是 DateTime 没有加？实体查询的时候会导致程序崩溃！是奔溃！不是报错哦！如果改成

[SugarColumn(ColumnName = "approval_time", ColumnDescription = "审核时间"**,IsNullable =true**)] public DateTime? approval_time { get; set; }
就没有问题

您好，如果我有一个CommonController通用方法想调用数据库的存储过程这个要写在哪里呢

Exception middle ware with serilog

I am not using Log4 dot net.insted of lo4.net i am using serilog

private static readonly log4net.ILog log =
log4net.LogManager.GetLogger(typeof(ExceptionHandlerMidd));

so please help me How to Configure serilog in Exception middleware

PermissionController /GetTreeTable 没有按照 OrderSort 进行排序，导致前端的显示效果不好

建议可以按照下面来进行处理一下
if (key != "")
{
permissions = permissionsList.Where(a => a.Name.Contains(key)).OrderBy(a => a.OrderSort).ToList();
}
else
{
permissions = permissionsList.Where(a => a.Pid == pid).OrderBy(a => a.OrderSort).ToList();
}

我在用JWT这步时报了一个错误

System.ArgumentException:“IDX12709: CanReadToken() returned false. JWT is not well formed: '[PII is hidden]'.
The token needs to be in JWS or JWE Compact Serialization Format. (JWS): 'EncodedHeader.EndcodedPayload.EncodedSignature'. (JWE): 'EncodedProtectedHeader.EncodedEncryptedKey.EncodedInitializationVector.EncodedCiphertext.EncodedAuthenticationTag'.”

疑似发现aop事务存在问题

起初是在自己的项目里，使用aop事务出现了This SqlTransaction has completed; it is no longer usable.的问题，后发现是在services层调用多个Repository层方法时，可能在services方法未执行完成的情况下，提交了事务。
后下载了博主的源码。也发现了类似的问题。

这里访问第一个数据访问层方法

然后就进了aop，接着断点就开始乱跳


在访问第三个数据访问层方法之前，工作单元就会提交事务(实际上也可能直接跟着图2继续执行下去)

接着就会报This SqlTransaction has completed; it is no longer usable.的问题
但是在我的项目里数据库操作是会成功的，用的是mssql
怀疑是否有可能是拦截器和service层并行了导致的，因为都是异步方法。
感谢群主开源，对.Net社区做的贡献。

autofac 组件在6.0版本出现注入失败问题

Castle.DynamicProxy.ProxyGenerationException: This is a DynamicProxy2 error: Target type for the proxy implements Castle.DynamicProxy.IProxyTargetAccessor which is a DynamicProxy infrastructure interface and you should never implement it yourself. Are you trying to proxy an existing proxy?
