我有一个C#应用程序,试图从该应用程序向C++函数发送参数。但是,我得到了错误(在主题中提到)
C#应用程序:
static class SegmentationFunctions
{
[DllImport("MyApplication.dll", EntryPoint = "fnmain", CallingConvention = CallingConvention.Cdecl, CharSet = CharSet.Ansi)]
public static extern int fnmain(string search);
}
}
public partial class MainWindow:Window
{
public MainWindow()
{
InitializeComponent();
string search = "test string here";
int scommand = SegmentationFunctions.fnmain(search);
}
C++文件.h
extern "C" QUERYSEGMENTATION_API int fnmain(char query[MAX_Q_LEN]);
C++文件.cpp
extern "C" QUERYSEGMENTATION_API int fnmain(char searchc[MAX_LEN_Q])
{
do something...
}
最佳答案
Dependency Walker可以向您展示从DLL中有效导出了哪些功能。您将能够看到您的fnmain
是否存在,或者是否是_fnmain
,或者名称中具有C++装饰。
