P\Invoke 签名错误

发布于 2024-12-13 10:18:02 字数 691 浏览 0 评论 0原文

当我尝试使用带有以下函数的 p\invoke 的函数时出现错误

声明

extern "C" __declspec(dllexport) HRESULT Get_GetLastHR(HANDLE);

定义

HRESULT Get_GetLastHR(HANDLE _xmlParser ){
return ((FCEXMLParser*)_xmlParser)->GetLastHR();
}

VB.Net 中使用的 p\Invoke 签名

Public Shared Function Get_GetLastHR(ByVal param0 As System.IntPtr) As Integer

*错误*

*对 PInvoke 函数“FeeCalculator!FeeCalculator.FeeEngine.FeeEngineMethods::Get_GetLastHR”的调用有堆栈不平衡。这可能是因为托管 PInvoke 签名与非托管目标签名不匹配。检查PInvoke签名的调用约定和参数是否与目标非托管签名匹配。*

使用的签名是否有问题？

I am getting error when I was trying to use function using p\invoke with following function

declaration

extern "C" __declspec(dllexport) HRESULT Get_GetLastHR(HANDLE);

definition

HRESULT Get_GetLastHR(HANDLE _xmlParser ){
return ((FCEXMLParser*)_xmlParser)->GetLastHR();
}

p\Invoke signature used in VB.Net

Public Shared Function Get_GetLastHR(ByVal param0 As System.IntPtr) As Integer

*ERROR*

*A call to PInvoke function 'FeeCalculator!FeeCalculator.FeeEngine.FeeEngineMethods::Get_GetLastHR' 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.*

Is there any problem with the signature used?
