“/”应用程序中的服务器错误。

拒绝访问路径“$（sourceFolder）\基础\文章\序列化”。
**说明：**在执行当前Web请求期间发生未处理的异常。请查看堆栈跟踪以了解有关错误以及代码中错误来源的详细信息。
**异常详细信息：**系统.未授权访问异常：对路径“$（sourceFolder）\基础\文章\序列化”的访问被拒绝。

ASP.NET未被授权访问所请求的资源。请考虑将对该资源的访问权限授予ASP.NET请求标识。ASP.NET具有基进程标识（在IIS 5上通常为{MACHINE}\ASPNET，在IIS 6和IIS 7上通常为Network Service，在IIS 7.5上通常为已配置的应用程序池标识）。如果应用程序通过身份将是匿名用户（通常是IUSR_MACHINENAME）或经过身份验证的请求用户。
若要授予ASP.NET对文件的访问权限，请在文件资源管理器中右键单击该文件，选择“属性”并选择“安全”选项卡。单击“添加”以添加相应的用户或组。突出显示ASP.NET帐户，并选中所需访问权限的复选框。

我尝试了以下建议：
Problems with error: "Access to the path is denied."

**1）**开放式互联网信息系统（IIS）管理员
**2）**展开要修改的站点（单击名称旁边的加号）**3）右键单击您希望能够写入文件的目录，然后选择编辑权限****4）单击安全选项卡5）**单击组和用户列表下的编辑...**6）**从“组或用户名”中选择IIS_IUSRS请确保为“写入”选中了“允许”复选框。

ASP.NET is not authorized to access the requested resource when accessing temp folder
一个非常简单的解决我的问题的方法，在IIS中，我必须右键单击应用程序池并将.NET Framework V4设置为集成而不是经典/。另一个解决方案是将正在访问的特定文件夹设置为对需要它的用户进行读/写，这可以由唯一用户或组织内的一组用户完成
（https://stackoverflow.com/a/47503132/19587900）

**（1）我已转到wwwroot文件夹。右键单击“安全”选项卡。提供了IISUSER以设置对wwwroot文件夹的读写权限。（2）**已将应用程序池更改为单独的池，并将标识设置为应用程序池标识。

Iv尝试了其他的东西，但到目前为止没有成功
