偶尔访问“C:\Windows \TEMP\\”文件

在我的ASP.NET MVC应用程序中,当我尝试从Microsoft Reporting Services程序集打开或生成LocalReport时,有时会遇到以下错误:

Microsoft.Reporting.WebForms.LocalProcessingException: An error occurred during local report 处理。---gt; Microsoft.Reporting.DefinitionInvalidException: The definition of the report c:\eNETPU\www.根目录\报告\报告\待定 Microsoft.ReportingServices.ReportProcessing.ReportProcessingException: An unexpected error occurred in Report 处理。---gt; System.UnauthorizedAccessException: Access to the path 'C:\WINDOWS\TEMP\expression_host_b5ec9f67a3ab42cfb53a75588aed6f75.dll' is denied.

或

System.Web.HttpUnhandledException: 类型例外 被扔了。---gt; Microsoft.Reporting.WebForms.LocalProcessingException: An error occurred during local report 处理。---gt; Microsoft.Reporting.DefinitionInvalidException: The definition of the report 'Main Report' is invalid. ---gt; Microsoft.ReportingServices.ReportProcessing.ReportProcessingException: An unexpected error occurred in Report 处理。---gt; System.UnauthorizedAccessException: Access to the path 'C:\WINDOWS\TEMP\expression_host_a1670a6e6b96411790645cb12e50897d.dll' is denied.

What can be the reason? Most of the time it works so it's not security issue. How do I fix it?

这里是 what I've found but I'd not like to use "use fields instead of report parameters" solution.
