解决方案

该文件夹的应用程序池授予权限。所以，你会去到C：\ FileStorage文件夹在Windows和编辑权限，并添加IIS APPPOOL \ appPoolNameHere作为一个用户，然后给它充分的权限

希望有所帮助。

修改的

分步说明...

- 开放Windows资源管理器

-browse到你的文件夹

- 右单击该文件夹并选择属性。

-On安全选项卡上单击编辑

- 单击添加

- 下层位置，确保它指向本地计算机，而不是域

- 对于对象的名称，下面进入，但你的应用程序池的名称替换MyAppPool ...

IIS APPPOOL \ MyAppPool

- 设置权限为完全，或只加写，或任何你需要的。

I simply have a web api application on IIS server that simply writes to text file on C:\FileStorage\test.txt however when I call this webservice I get the internal 500 error, after expanding the error,I get the following error, how do I grant write access to this web service on IIS server?

"ExceptionMessage": "Access to the path 'C:\\FileStorage\\test.txt' is denied.",
"ExceptionType": "System.UnauthorizedAccessException",
"StackTrace": "   at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)\r\n   at 

Grant permissions for that folder to the application pool. So you'd go to the C:\FileStorage folder in Windows and edit permissions, and add IIS APPPOOL\appPoolNameHere as a user, then give it full permissions.

Hope that helps.

EDIT

Step by Step Instructions...

-Open Windows Explorer

-Browse to your folder

-Right click the folder and go to Properties

-On the Security tab click Edit

-Click Add

-Under Locations, make sure it is pointing at your local machine, not a domain

-For the object name, enter below but replace MyAppPool with the name of your application pool...

IIS APPPOOL\MyAppPool

-Set the permissions to Full, or just add Write, or whatever you need.
