.NET 4.0中的异常. [英] exception in .net 4.0.

问题描述

大家好，

当我尝试使用以下代码时

Hi all,

When i try to use below code

ChartType = "line";
           chart1.ChartAreas["Default"].AxisX.ArrowStyle = AxisArrowStyle.SharpTriangle;
           chart1.ChartAreas["Default"].AxisY.ArrowStyle = AxisArrowStyle.SharpTriangle;

我收到以下异常，可能是什么问题?

在"ChartAreaCollection"中找不到名称为"Default"的图表元素.
----预先感谢---------

I get the following exception, what could be the problem ??

A chart element with the name ''Default'' could not be found in the ''ChartAreaCollection''.
---- thanks in advance ---------

推荐答案

确保图表区域集合中确实存在名为"Default"的区域图1.
要么完全丢失，要么名称不同.

Make sure an area named ''Default'' does exist in the chart areas collection of chart1.
Either this is completely missing or the name is different.

在WinForms设计器中设计图表时，必须修改名为ChartAreas的属性.创建的默认区域称为默认".您似乎已将其更改为其他内容.因此，您可以做的是:在代码中更改默认"或仅将设计器中的图表区域重命名为默认"

When designing your chart in the WinForms designer, you must modify the property called ChartAreas. The default area that is created is called "Default". You seem to have changed it to something different. So what you could do is: Change "Default" in your code or just rename the chart area in your designer to "Default"
