运行 VB.Net 图表示例未使用 .NET v4.0.30319 编译
Running VB.Net Chart Example Not Compiling with .NET v4.0.30319
我正在尝试使用命令行从此处使用 MSChart 控件编译示例程序：

VB 编译器然后抛出错误 "Type Chart is not Defined" 我已经在上面的代码中做了 "Imports System.Windows.Forms.DataVisualization.Charting"
Chart1 对象的声明也存在一些问题。
感谢任何帮助。
您需要更多参数才能 vbc.exe。
我将您的程序复制到 VS2015 中作为 "WindowsApplication3" 并针对 .NET Framework 4.5.2、任何 CPU、调试模式编译它，并获得以下命令行来编译它：

您应该能够看到您需要哪些部件，或参考Visual Basic Command-Line Compiler了解详情。
最后我想出了如何使用命令行进行编译：
