C#--異常--函數調用導緻堆棧不對稱

1、異常提示資訊為：函數調用導緻堆棧不對稱。原因可能是托管的 PInvoke 簽名與非托管的目标簽名不比對。

2、出現場景：這種異常大多出現在C#調用C++的動态庫時。

3、處理方法

把 [DllImport("winmm.dll", EntryPoint = "sndPlaySoundA",)]

改為[DllImport("winmm.dll", EntryPoint = "sndPlaySoundA" , CallingConvention = CallingConvention.Cdecl)]

//C#中引入C++ DLL庫
//[DllImport("bq80xrw.dll", EntryPoint = "GetAdapterFWVersion")]
[DllImport("bq80xrw.dll", EntryPoint = "GetAdapterFWVersion, CallingConvention = CallingConvention.Cdecl)]
public static extern int GetAdapterFWVersion([MarshalAs(UnmanagedType.LPStr)]string FWVersion);
