A function call causes a stack asymmetry. The reason may be that the managed PInvoke signature does not match the unmanaged target signature.

When C # introduces an external unmanaged class library, there are times when "the call to the PInvoke function causes stack asymmetry." The reason may be that the managed PInvoke signature does not match the unmanaged target signature "error.

This problem is usually resolved by adding the attribute callingconvention=callingconvention.cdecl to the DllImport tag.

Such as:
[DllImport ("AutoAnalyse.dll", entrypoint= "Measure", Callingconvention=callingconvention.cdecl)]
public static extern string Measure (string Basekey, string project);
