const int MAX_PATH = 260;
const int RAS_MaxEntryName = 256;
[StructLayout(LayoutKind.Sequential,CharSet=CharSet.Auto)]
struct RASENTRYNAME {
public int dwSize;
[MarshalAs(UnmanagedType.ByValTStr,SizeConst=RAS_MaxEntryName+1)]
public string szEntryName;
[MarshalAs(UnmanagedType.ByValTStr,SizeConst=MAX_PATH)]
public string szPhonebook;
public int dwSubEntry;
}
Sample Code:
int cb=Marshal.SizeOf(typeof(RASENTRYNAME)),entries=0;
RASENTRYNAME[] entryNames=new RASENTRYNAME[1];
entryNames[0].dwSize=Marshal.SizeOf(typeof(RASENTRYNAME));
//Get entry number
uint nRet=RasEnumEntries(IntPtr.Zero,IntPtr.Zero,entryNames,ref cb,ref entries);
if(entries==0) return;
_EntryNames=new string[entries];
entryNames=new RASENTRYNAME[entries];
for(int i=0;i<entries;i++)
{
entryNames[i].dwSize=Marshal.SizeOf(typeof(RASENTRYNAME));
}
nRet=RasEnumEntries(IntPtr.Zero,IntPtr.Zero,entryNames,ref cb,ref entries);
for(int i=0;i<entries;i++)
{
_EntryNames[i]=entryNames[i].szEntryName;
}
