I have two `List<FileInfo>` and I want to return the common `FileItem` between them.

```
List<FileInfo> outputList = new List<FileInfo>();
outputList = list1.Intersect(list2).ToList();

```

However, I'm getting back an empty List.

Both the lists contain `FileInfo`'s found by 

```
System.IO.DirectoryInfo dir = new System.IO.DirectoryInfo(startFolder);
IEnumerable<System.IO.FileInfo> fileList = 
dir.GetFiles("*.*", System.IO.SearchOption.AllDirectories);

```

And filtered by queries.
