UNICODE与ANSI转换的MSDN上的例子

The following sample code is a function (GetFullName) that takes a user name and a domain name in the first two arguments and returns the user's full name in the third argument.

#include <windows.h>
#include <lm.h>
#include <stdio.h>
BOOL GetFullName( char *UserName, char *Domain, char *dest )
{
    WCHAR wszUserName[UNLEN+1]; // Unicode user name

    WCHAR wszDomain[256];
    LPBYTE ComputerName;
    struct _SERVER_INFO_100 *si100; // Server structure

    struct _USER_INFO_2 *ui; // User structure

// Convert ANSI user name and domain to Unicode

    MultiByteToWideChar( CP_ACP, 0, UserName,
        strlen(UserName)+1, wszUserName,
     sizeof(wszUserName)/sizeof(wszUserName[0]) );
    MultiByteToWideChar( CP_ACP, 0, Domain,
        strlen(Domain)+1, wszDomain, sizeof(wszDomain)/sizeof(wszDomain[0]) );
// Get the computer name of a DC for the domain.

    NetGetDCName( NULL, wszDomain, &ComputerName );
// Look up the user on the DC.

    if( NetUserGetInfo( (LPWSTR) ComputerName,
        (LPWSTR) &wszUserName, 2, (LPBYTE *) &ui ) )
    {
        printf( "Error getting user information.\n" );
        return( FALSE );
    }
// Convert the Unicode full name to ANSI.

    WideCharToMultiByte( CP_ACP, 0, ui->usri2_full_name, -1,
        dest, 256, NULL, NULL );
    return (TRUE);
}
