Updating an access file using c

We do not want to go with creating connection and check connection availability and do not want to be dependent on another server because it’s time-consuming.Just for example, if a project has no database connectivity and would like to store single user information, here we can use a JSON file to store such data.After reading file data, first, parse the JSON data using JObject. Once you get JObject, which is nothing but an array, we can directly access all data points to pass key.

I added new rows to the Customers table with Customer Id, Customer Name, and Company Name (named Tst ID, Lana Jackob, and Mindcracker Inc., respectively). Adding data using a Data Adapter's Update method Listing 5-49 shows an example that edits row data.

So, create a console application in Visual Studio using C# and add a JSON file named "user.json".

Add the following line of code inside the file so that we can perform CRUD operation on this.

Therefore, this JSON file contains user information like user id, name, address, experiences etc.

The next code will show you the process to selecting user data, updating the existing data, inserting the new experience, and deleting the user experience. private string json File = @"C:\Users\mk9\Documents\visual studio 2015\Projects\Json Add And Update\Json Add And Update\user.json"; Before you proceed further, you need to add reference for Newtonsoft.

As you saw in the Data Table, Data Row, and Data Column sections at the beginning of this article, you can use the Delete method of a Data Row to delete a row.
