Windows compare folders recursively2/1/2024 ![]() Public int GetHashCode(System.IO.FileInfo fi)Ĭreate a C# console application project, with using directives for the System.Linq and System.IO namespaces. reference identity, it is possible that two or more objects will produce the same ![]() Because equality as defined here is a simple value equality, not rules for IEqualit圜omparer, if Equals is true, then the hash codes must Return a hash that reflects the comparison criteria. Public bool Equals(System.IO.FileInfo f1, System.IO.FileInfo f2) of the files being compared and their length in bytes.Ĭlass FileCompare : 圜omparer This implementation defines a very simple comparison Keep the console window open in debug mode.Ĭonsole.WriteLine("Press any key to exit.") Select file).Except(list2, myFileCompare) Ĭonsole.WriteLine("The following files are in list1 but not list2:") For this example we only check one way. Find the set difference between the two folders. Var quer圜ommonFiles = list1.Intersect(list2, myFileCompare) Ĭonsole.WriteLine("The following files are in both folders:") Ĭonsole.WriteLine(v.FullName) //shows which items end up in result listĬonsole.WriteLine("There are no common files in the two folders.") The query executes immediately because it returns a bool.īool areIdentical = list1.SequenceEqual(list2, myFileCompare) Ĭonsole.WriteLine("the two folders are the same") Ĭonsole.WriteLine("The two folders are not the same") The problem is that in the second folder, the files are named very differently. that is defined in the FileCompare class. The first folder has duplicate files that exist in the second folder. identical file lists, based on the custom file comparer For Folder: Filter, if you want to compare all different types of file types, use. Do the same for the file or folder you want to compare in the 2 nd File or Folder space. This query determines whether the two folders contain in 1 st File or Folder, select Browse and choose the file or folder that you want to compare. ![]() IEnumerable list2 = dir2.GetFiles("*.*", System.IO.SearchOption.AllDirectories) įileCompare myFileCompare = new FileCompare() IEnumerable list1 = dir1.GetFiles("*.*", System.IO.SearchOption.AllDirectories) System.IO.DirectoryInfo dir2 = new System.IO.DirectoryInfo(pathB) String pathA = pathB = dir1 = new System.IO.DirectoryInfo(pathA) on a local drive and change these file paths. Create two identical or different temporary folders If you need to recurse into the subdirectories, you need to use a batch script using a FOR loop and the PUSHD and POPD command. Use a syntax like COMP c:\folder1 c:\folder2 to compare all files in folder1 with the content of folder2. In a real-world scenario, you should modify this comparer to perform a more rigorous equality check. To compare sets of files, use wildcards in data1 and data2 parameters. It just uses the name and length in bytes of each file to determine whether the contents of each folder are identical or not. The class is not intended for use in real-world scenarios. The FileComparer class shown here demonstrates how to use a custom comparer class together with the Standard Query Operators. The techniques shown here can be adapted to compare sequences of objects of any type.
