error LNK2001-use C functions in managed assembly class

In an managed assembly class, I need to use malloc() and other C functions. But when compiling, it generated errors like

error LNK2001: unresolved external symbol "void * __cdecl malloc(unsigned int)" (?malloc@@$$J0YAPAXI@Z)

HashCPP error LNK2001: unresolved external symbol "unsigned int __cdecl wcstombs(char *,unsigned short const *,unsigned int)" (?wcstombs@@$$J0YAIPADPBGI@Z)
If change Configuration Type from Dynanic Library (.dll) to
Static Library (.lib), I could compile it without an error.

But I need to use these functions in dynamic library, so that the libraray can be used by other languages like C#, VB.NET.

Please help

Thanks
Keith
