此应用程序在较早的服务器中运行良好，当我们将其移植到新服务器时，我们遇到了这个问题。这个错误背后的真正问题是什么？请建议

我们得到的错误如下：

Server Error in '/' Application.

Stream does not support writing.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

Exception Details: System.NotSupportedException: Stream does not support writing.

Source Error: 

The source code that generated this unhandled exception can only be shown when compiled in debug mode. To enable this, please follow one of the below steps, then request the URL:

1. Add a "Debug=true" directive at the top of the file that generated the error. Example:

  <%@ Page Language="C#" Debug="true" %>

or:

2) Add the following section to the configuration file of your application:

<configuration>
   <system.web>
       <compilation debug="true"/>
   </system.web>
</configuration>

Note that this second technique will cause all files within a given application to be compiled in debug mode. The first technique will cause only that particular file to be compiled in debug mode.

Important: Running applications in debug mode does incur a memory/performance overhead. You should make sure that an application has debugging disabled before deploying into production scenario.

感谢您在解决此问题方面提供的帮助。此应用程序基于 mysql db 构建，用于此站点的 asp.net 版本为 2.0
