C# call C Dll methods

[alag20]

Hi,
I am trying to use a dll written by 3rd party which has the following 4 methods.

__declspec(dllexport) UINT IniReadI (LPCSTR szS1,LPCSTR szE1,int nD1,LPCSTR szF1)
 
__declspec(dllexport) int IniReadS (LPCSTR szS1,LPCSTR szE1,LPCSTR szD1,LPSTR szRB,int nSOB,LPCSTR szF1)
 
 

Can someone please tell me how can i use these from .Net. I know i will need to use DllImport. Any help or example will be appreciated as it is very urgent:)


Thanks in advance.

HI,
Just add the declaration for the method in your class , add attribute of Dllimport[..] to that method . once you did it.. call that method where inside that class.You can google the usage of DllImport attribute .

Thanks

Thanks.... I tried that and DllImport says entry point not found.

I added an extern "C"{ decl.... } and it seems to do the trick...


Thanks
