Tempo fa avevo la necessità di usare delle Windows API (Application Programming Interface) in un mio progetto Visual C# che stavo implementando con Visual Studio 2005, facendo qualche ricerca in internet ho scoperto che con il Prompt dei comandi di Visual Studio 2005 (installato di default insieme ad Visual Studio) si poteva estrarre e quindi visualizzare la lista completa di API (o funzioni) contenute in un file DLL (Dynamic-Link Library) usando un apposita utility da riga di comando chiamata DUMPBIN.
Dumpbin contiene un apposito comando chiamato : /EXPORTS la sintassi completa per esportare tutte le API di una determinata DLL e :
Dumpbin /EXPORTS /OUT: Nome_File_output.txt %windir%\System32\Nome_File.dll
/EXPORTS ...............................(comando per l’esportazzione)
/OUT: Nome_File_output ........(parametro che indica il nome del file dove salvare la lista di API esportate dalla DLL)
%windir%\System32\Nome_File.dll (è il percorso dove è collocata la DLL, nel nostro caso in Windows\System32\Nome_Del_File.dll)
Le dll da dove si possono esportare le API sono molte, le principali sono :
User32.dll, Kernel32.dll, Shell32.dll, advapi32.dll, wininet.dll, netapi32.dll, ecc.
Un esempio di esportazione in un file è :
dumpbin /EXPORTS /OUT: User32.dll_.txt %windir%\System32\User32.dll
e l’output che si salva nel file chiamato User32.dll_.txt è esattamente questo :
Dump of file C:\WINDOWS\System32\User32.dll
File Type: DLL
Section contains the following exports for USER32.dll

Una volta individuata l’API che pensate che faccia al caso vostro fate una ricerca in internet per approfondire la sintassi di utilizzo e poi potete usarla nelle vostre applicazioni scritte in C# usando una semplice sintassi :
Innanzitutto dovete aggiungere la direttiva using:
using System.Runtime.InteropServices;
per poter usare DllImport(Nome_File) la sintassi finale di utilizzo è :
[DllImport("User32.dll")]
public static extern int MessageBox(int h, string m, string c, int type);
fatto questo potete finalmente utilizzare la vostra Windows API che nel nostro caso è la MessageBox(), nella dichiarazione come vedete dovete specificare la parola chiave extern per informare il compilatore che l’implementazione della funzione è per l'appunto esterna contenuta nella dll specificata nella DllImport, quindi a noi basta solo richiamare (subito dopo avere specificato in quale dll si trova) la sua interfaccia. 
E per finire usiamo questa benedetta API :
private void btnMessage_Click ( object sender, EventArgs e)
{
MessageBox (0,"API Message Box","API Demo",0);
}
Ciao a tutti e alla prossima
