This short tutorial shows you how to compare CSV files using C#. This guide contains complete information for comparing the CSV files, configuring the document comparison package, and working code snippet to demonstrate the implementation of the C# compare CSV files functionality. Below you can find steps to do a document comparison and a sample code.

Steps to Compare CSV Files using C#

1. Install GroupDocs.Comparison for .NET package from the NuGet package manager for comparing CSV files
2. Add a reference to the GroupDocs.Comparison namespace for implementing the comparison functionality for CSV files
3. Load the source CSV file by initializing the Comparer class
4. Call the Add method of the Comparer class for loading the target CSV file
5. Call the Compare method of the Comparer class for saving the resultant CSV file to the disk

In the preceding section, we have listed stepwise instructions to create the compare two CSV files in C# functionality. The Comparer class allows users to do the document comparison, first pass the source CSV file to its constructor, and then use Add method to load the target CSV file. Finally, the Compare method allows saving the output CSV document to the disk.

Code to Compare CSV Files using C#

We have used the points explained in the previous section for comparing CSV files and developed the compare two CSV files and highlight differences in C# functionality. To complete the document comparison in the above code snippet, we have consumed a few API calls of the document comparison package and this code does not depend on any other third-party software. Moreover, you may alter this example as per your specific requirement and run it on any operating system like MS Windows, Linux, and Mac OS that support the .NET environment.

We have discussed the detailed process of how to compare CSV files in C# and produced a functional example for it. Recently, we published an article on comparing images using C#, have a look at how to Compare Images in C# guide for more information.
