示例1: GetMerit
private static Merit GetMerit(IBaseFilter filter)
{
Guid clsid;
int hr;
hr = filter.GetClassID(out clsid);
if (hr != 0)
{
return Merit.DoNotUse;
}
//check cache
if (_meritCache.ContainsKey(clsid))
{
return _meritCache[clsid];
}
//figure new value
try
{
RegistryKey filterKey =
Registry.ClassesRoot.OpenSubKey(@"CLSID\{083863F1-70DE-11d0-BD40-00A0C911CE86}\Instance\{" + clsid.ToString() +
@"}");
if (filterKey == null)
{
