Compare two TXT using C#

Highly accurate C# diff checker to compare TXT files and find differences between them

Our powerful C# SDK allows you to find the difference between TXT documents and save the results to a convenient format for viewing. To verify our product capabilities, compare TXT files using this C# library and see the differences.

Compare TXT in C#

Our .NET SDK is designed to give you the most accurate result, even though comparison is a complex function itself.

Sometimes you need to be sure that the document in the TXT format has not been changed, and if it has, you need to find out what the difference is. Just use our .NET diff tool to compare two TXT files and find differences in whole words or single characters. Moreover, if only one character in a word has changed, this word will be marked as changed entirely.

Now you no longer need to spend time manually comparing TXT documents, and you can quickly find even small changes and export such diffs to a document in a convenient format.

Try to compare TXT documents

Check out how our solution to compare TXT files using .NET SDK works. To achieve this, load the TXT files you want to compare and select the export file format – it will be automatically loaded after comparing.

Note that you need to accept all revisions in compared documents before calling the comparison method, as shown in our example:

await wordsApi.CompareDocument(compareDocumentRequest);

//  Download result document from cloud storage.
var downloadFileRequest = new DownloadFileRequest(fileResult);
var downloadFileResult = await wordsApi.DownloadFile(downloadFileRequest);
using (var fileStream = File.Create(fileResult))
