User-Defined Types:

None.

Alternative Managed API:

Use System.Net.NetworkInformation.IPGlobalProperties.GetIPGlobalProperties().

Note that ScopeId is renamed to DhcpScopeName and EnableProxy is renamed to IsWinsProxy.

Notes:

Returns a FIXED_INFO struct.

Tips & Tricks:

Please add some!

Sample Code:

IntPtr infoPtr = IntPtr.Zero;

int infoLen = Marshal.SizeOf(typeof(FIXED_INFO));

int ret;

while (true)

{

    infoPtr = Marshal.AllocHGlobal(Convert.ToInt32(infoLen));
    ret = GetNetworkParams(infoPtr, ref infoLen);

    if (ret == ERROR_BUFFER_OVERFLOW)
    {
        //try again w/ bigger buffer:
        Marshal.FreeHGlobal(infoPtr);
        continue;
    }

    if (ret == ERROR_SUCCESS)
        break;

    throw new ApplicationException("An error occurred while fetching adapter information.", new Win32Exception(Convert.ToInt32(ret)));

}

FIXED_INFO info = (FIXED_INFO)Marshal.PtrToStructure(infoPtr, typeof(FIXED_INFO));
