c# - Visual Studio 2017中的Pythonnet

我试图在微软Visual Studio 2017社区中以窗口形式使用Pythonnet运行Visbrain，但我遇到了下面的一些问题。
环境
1）Pythonnet版本：v2.3.0
我从Visual Studio 2017社区的“Manage Nuget Package”下载了这个。
2）Python版本：Python 3.6.5（amaconda3）
已经在环境中pip install pythonnet。
3）操作系统：Window 7，64位
4）.net框架：4.0
===
尝试运行以下代码：

private static void button_Click(object sender, EventArgs e)
{
    using (Py.GIL())
    {
         dynamic myVisbrain = Py.Import("Visbrain");
    }
}

调试时
来自program.cs

Application.Run(new Form1()); // crashes here

错误消息：

Exception thrown: 'System.BadImageFormatException' in System.Windows.Forms.dll
An unhandled exception of type 'System.BadImageFormatException' occurred in System.Windows.Forms.dll
Could not load file or assembly 'Python.Runtime, Version=2.3.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. An attempt was made to load a program with an incorrect format.

想问一下，这里有什么问题，怎么解决。谢谢您。

最佳答案

检查“Python.Runtime”的引用
它可能指向32位版本，而您使用的是64位版本

\packages\pythonnet_py27_dotnet.2.3.0\lib\net40\x86\Python.Runtime.dll

把它改成

\packages\pythonnet_py27_dotnet.2.3.0\lib\net40\x64\Python.Runtime.dll

应用程序应该可以工作。
