Sample Code:
C#
string infFile = <INF file full path>;
uint ErrorLine = 0;
IntPtr infHandle = SetupOpenInfFile(infFile, null, INF_STYLE_OLDNT | INF_STYLE_WIN4, out ErrorLine);
int iCode = Marshal.GetLastWin32Error();
if (infHandle.ToInt64() != INVALID_HANDLE_VALUE)
{
Console.WriteLine("INF file was opened successfully.");
INFCONTEXT Context = new INFCONTEXT();
if (SetupFindFirstLine(infHandle, "Manufacturer", null, ref Context) == true)
{
Console.WriteLine("Manufacturers list:");
string manufacturerName = "";
manufacturerName = manufacturerName.PadLeft(256, ' ');
Int32 requiredSize = manufacturerName.Length;
SetupGetStringField(ref Context, 1, manufacturerName, manufacturerName.Length, out requiredSize);
manufacturerName = manufacturerName.Substring(0, requiredSize-1);
Console.WriteLine(manufacturerName);
while(SetupFindNextLine(ref Context, out Context) == true)
{
manufacturerName = manufacturerName.PadLeft(256, ' ');
requiredSize = manufacturerName.Length;
SetupGetStringField(ref Context, 1, manufacturerName, manufacturerName.Length, out requiredSize);
manufacturerName = manufacturerName.Substring(0, requiredSize - 1);
Console.WriteLine(manufacturerName);
}
}
else
{
Console.WriteLine("Can't find [Manufacturer] section.");
}
SetupCloseInfFile(infHandle);
}
else
{
Console.WriteLine("Failed to open INF file. Error code - {0}.", iCode);
if (ErrorLine != 0)
{
Console.WriteLine("Failure line - {0}.", ErrorLine);
