That line throws a null exception...can you look at the line that threw the exception and know what the issue is?

Writing all of your code in one big Main function is faster than any of this "object-oriented" nonsense.

And using C or assembly will be much faster than this JIT-compiled C# nonsense.

for(int i =0; i< 100; ++i)
 {...}

int i;
for(i =0; i< 100; ++i)
 {...}

I would be a bit surprised if your first point was true. Please give me a couple examples of optimizations that depend on function size.

foreach(string x in y)
{
   x = x.Trim().ToLower();
   DoSomething (x);
}

function DoSomething(string s)
{
   if (s.StartsWith("hello"))
   {
       s = "test";
   }
}

foreach(string x in y)
{
   x = x.Trim().ToLower();
   if (x.StartsWith("hello"))
   {
       x = "test";
   }
}

var vidsWithOutPics = vidList.Except(vidsWithPics).Where(v => !v.IsAlternateTitle);

var inDuration = DiskFile.GetAll().Where(df => !df.HasDuration).Select(df => df.Video).Distinct();

var noSizeList = videoFiles.Where(file => file.Bytes < 0 && files.Contains(file.Location));

var inDuration = DiskFile.GetAll().Where(df => !df.HasDuration).Select(df => df.Video).Distinct();

var inDuration = Distinct(Select(Where(DiskFile.GetAll(), Video), HasDuration));

Would you like to write and debug "Except" each time you need it?
