我试图实现这段代码（不幸的是，网站已经关闭，所以我不得不在互联网档案中挖掘）。
我在 RenderDot 函数中遇到错误：
PInvokeStackImbalance was detected
Message: A call to PInvoke function 'testing_graphs!testing_graphs.Graphviz::agmemread'
has unbalanced the stack. This is likely because the managed PInvoke signature does
not match the unmanaged target signature. Check that the calling convention
and parameters of the PInvoke signature match the target unmanaged signature.
该怎么办？这里有一个示例应用程序- 也许有人有它？
