ASP.NET Chart:我的web.config出了什么问题.我无法显示图表

Question

我刚刚创建了一个网页,其中包含一些带有几个数据点的准直图表进行测试.在localhost上,图表按预期显示没有问题.但是当我部署到我的webhost时,我得到了500 - 内部服务器错误

500 - Internal server error.
There is a problem with the resource you are looking for, and it cannot be displayed.

这是Visual Studio上传的web.config.你能告诉我这个web.config中有什么缺失或错误吗？appSettings在C:中看起来很可疑,但是如何更改呢？谢谢.

<?xml version="1.0"?>
<configuration>
<appSettings>
<add key="ChartImageHandler" value="storage=file;timeout=20;dir=c:\TempImageFiles\;" />
</appSettings>
<system.webServer>

  <remove name="ChartImageHandler" />
  <add name="ChartImageHandler" preCondition="integratedMode" verb="GET,HEAD,POST"   path="ChartImg.axd"  type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler, System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />

试试这个链接 http://asifhuddani.wordpress.com/2010/10/07/chart-control-asp-net-4-0-and-iis-7-problem/

然后删除dir = c:\ TempImageFiles \; 来自web.config
