asp中的错误：图表控件
我在我的网站中使用图表控件。代码和图表控件在我的本地计算机上完美运行。但是当我将它部署在网络服务器上时，它给出了错误。我还将网站的版本更改为 4.0，并在 web.config 中给出了所有选项卡和引用。
错误是

在这里，我无法确切地找到为什么目录 c:\TempImageFiles 出现目录错误，因为我没有在整个代码中使用此路径。
请任何人帮助我解决这一问题。

Here, I cannot find exactly why the directory error is giving for directory c:\TempImageFiles as i havent used anywhere in my entire code for this path.
Please can any one help me on this.

将以下条目添加到 Web 配置的 appsettings 部分。
如果那里已经有一个条目，则用该条目替换它。
编辑
相反，您可以提供文件夹的路径
或者有 这里有一篇文章，应该会给你很多值得尝试的东西。
Add the following entry to the appsettings section of your web config.
If there is already an entry there then replace it with this one.
EDIT
Instead you could supply a path to your folder
Alternatively there is an article here that should give you lots of things to try.
