Vb.net compare files in directory

I need to pick up one file in folder F1 and compare it with the same file in F2 and do it recursively to compare all files in F1 to compare the respective files in F2.

Input parameters to my application will be the path for folder F1 and F2 and than it will pick up each file one by one from path1 and will compare them with respective files at path2. I have an idea that you can go through the F1 folder to get the file names and folders recursively, for each file name, and then you can read both the content of file in the F1 and F2, therefore, you can do comparison for all the files in the F1 and F2.

Here is a recursive method which used for go through a folder, please check the code snippet below. GetDirectories sourceDir ; foreach string subdir in subdirEntries if File. The content you requested has been removed. Ask a question. The FileComparer class shown here demonstrates how to use a custom comparer class together with the Standard Query Operators. The class is not intended for use in real-world scenarios.

It just uses the name and length in bytes of each file to determine whether the contents of each folder are identical or not. In a real-world scenario, you should modify this comparer to perform a more rigorous equality check. Create a Visual Basic console application project, with an Imports statement for the System. Linq namespace. Skip to main content. Use the GetFiles String overload for a simple file search in a specified directory, without searching subdirectories.

You can use the wildCards parameter to specify a search pattern. To include subdirectories in the search, set the searchType parameter to SearchOption.

Use one of the FileSystem. GetFiles method overloads, supplying the name and path of the directory to search in the directory parameter.

The following example returns all files in the directory and adds them to ListBox1. The path is not valid because it is Nothing ArgumentNullException. The path exceeds the system-defined maximum length PathTooLongException.
