How Do I Read a CSV File in C Sharp? Your Complete Guide

When used appropriately, working with different programming languages can produce highly beneficial results. For example, an entrepreneur might be able to write a program in Python that can help them automate a large amount of work that they would otherwise be responsible for.

C# is one of the most common programming languages, and it can be used for a variety of different purposes. For those who are unaware, it’s entirely possible to read a CSV file by using C#. Let’s take a look at how you can do so.

What Is a CSV File?

A CSV file is a comma-separated values file. It’s possible to use this type of file with any programming language, and it will prove to be beneficial for doing things like merging multiple spreadsheets together.

You can also convert Excel files into CSV files, which are often used in web development scenarios. For example, if you’re trying to import different items into a shopping cart, it is possible to use one CSV per item. Once the files are combined together, you can use them to produce a unique shopping experience for your users.

How Can I Use C# to Read a CSV File?

In order to do this, you will need to add a reference in your C# code. In fact, there are two different ways to accomplish the task:

  • Use the System.IO library
  • Use a CSV class that is built into .NET Framework 4.5 or greater

The first option allows you to use a variety of different file types, including JSON and XML. However, the second option is more efficient when it comes to reading CSV files.

Once you’ve added a reference in your C# code (make sure to add System.IO), all you need to do is use the following type of method:

System.IO.StreamReader csvFile = new StreamReader(“fileName.csv”);

In the code above, csvFile is a variable that can be used to reference your CSV file. In order to make sure it works properly, you’ll need to open up a Visual Basic console or Visual Studio console.

NET Command Prompt and type “.” after the name of the file that you’re trying to open.

For instance, the following command will work:


From there, if you hit enter, the file should open up in your C# console and it will be read properly. Once you’re finished with the file, make sure to close it so that other programs can access the information stored inside of it.
