Summary

Enumerates all of the wireless NICs currently plugged into the system.

- The string that is returned is localized (seems to use the system language).

I needed to enumerate the installed code pages on a Windows machine, and wanted to present the possible encoding interpretations to a user via a ComboBox. By using the Win32 API ::EnumSystemCodePages() via PInvoke, and the System.Text.Encoding.GetEncoding() static method, I could get the mapping from the code page to an Encoding instance which returns "pretty" names like 'Japanese (Shift-JIS)'.

private static extern System.IntPtr GetCommandLine();

.

The original GetCommandLine function returns a pointer to a buffer allocated and owned by the operating system. When marshaling strings as return types, the interop marshaler assumes it must free the memory that the original LPTSTR type pointed to by the function. To prevent the marshaler from automatically reclaiming this memory, the managed GetCommandLine prototype returns an IntPtr type instead of a string. The Marshal.PtrToStringAuto method copies the unmanaged LPSTR type to a managed string object, widening the character format, if required.

.

System.IntPtr ptr = GetCommandLine();
