问题描述：

我有制作饼图的要求。我使用了syncfusion，并在.aspx页面中注册，并在.aspx.cs页面中使用了库。虽然我试图运行它显示错误。我如何解决它？ enter image description hereSyncfusion饼图错误

我们已经分析了查询。我们试图用提供的代码片段复制报告的场景，但不幸的是我们无法复制它，我们怀疑程序集在您的最后没有在web.config文件中正确引用。我们准备了一个样本，其中我们已经提供了有关您的代码片段的饼图。由于我们不知道您的数据源，因此我们已将随机数据提供给图表并呈现它。按照以下步骤呈现图表。

所需要的渲染器图表控制DLL的在下面列出。

  • Syncfusion.Core.dll
  • Syncfusion.Chart.Base.dll
  • Syncfusion.Chart.Web.dll
  • Syncfusion.Shared.Base.dll
  • Syncfusion.Shared.Web。 DLL
  • Syncfusion.Tools.Web.dll

然后在Web.config文件中添加以下命名空间。

<configuration> 
    <system.web> 
    <compilation > 
     <assemblies> 
     <add assembly="Syncfusion.Chart.Web" /> 
     <add assembly="Syncfusion.Chart.Base" /> 
     <add assembly="Syncfusion.Shared.Web" /> 
     <add assembly="Syncfusion.Tools.Web" /> 
     <add assembly="Syncfusion.Shared.Base" /> 
     <add assembly="Syncfusion.Core" /> 
     </assemblies> 
    </compilation> 
    </system.web> 
</configuration>

添加处理程序在Web.config文件来呈现网页图表。

<handlers> 
     <add name="syncfusion_generate" path="syncfusion_generate.ashx" verb="*" 
       type="Syncfusion.Web.UI.WebControls.Chart.ChartWebHandler,Syncfusion.Chart.Web"/> 
</handlers>

供参考的样本可以从下面找到。
