Visualc#, like other development tools, can also call api functions of dynamic link libraries. Yes. Net framework itself provides such a service, which allows governed code to call ungoverned functions implemented in dynamic link libraries, including windowsapi functions provided by the operating system. It can locate and call the output function and organize its parameters (integer, string type, array, structure, etc. ) Cross interoperability boundaries as needed.

Declaration of dynamic link library function

The function of dynamic link library must be declared before use. Compared with VB, the declaration of C # function is more verbose. The former can be used directly after being pasted by apiviewer, while the latter needs some additional modification of parameters.
