检测到PInvokeStackUnbalance

问题描述

嗨
我正在尝试使用第三方本机dll.在我的.net应用程序中.我正在使用c#.本机dll中的功能.具有以下声明:

Hi
I am trying to use a third party native dll. in my .net application. I am using c#. The function in native dll. has the following declaration:

void _stdcall pir_learnCCF( const char * serial, unsigned char state );

使用PInvoke Interop助手，我可以进行以下导入:

With the PInvoke Interop assistant I get the following import:

[DllImport("PIRLIB.dll", EntryPoint = "pir_learnCCF")]
public static extern void pir_learnCCF(
[InAttribute()] [MarshalAsAttribute(UnmanagedType.LPStr)] string serial,
byte state);

我有以下问题.使用PInvoke互操作助手时，我必须从非托管函数定义中删除"_stdcall"，否则助手会生成错误.在删除"_stdcall"之后，助手会生成上述使用语句，但是当我尝试调用该函数时，会检测到PInvokeStackUnbalance.第三方dll.具有其他功能，这些功能通常可以与Interop Assistant生成的导入语句一起使用.任何建议将不胜感激.

I have the following questions. When using PInvoke interop assistant I have to remove the "_stdcall" from unmanaged function definition, otherwise the assistant generates an error. After I remove the "_stdcall" the assistant generates the above using sentence but when I try to call the function I get the PInvokeStackUnbalance detected. The third party dll. has other functions which work normally with import sentences generated by the Interop Assistant. Any advice will be appreciated.

推荐答案

DllImport("PIRLIB.dll", EntryPoint = "pir_learnCCF", CallingConvention = CallingConvention.Cdecl)]
public static extern void pir_learnCCF(string serial, byte state);
